CHARTER*
Mina Qaboos, the premier seaport in the Sultanate
of Oman, lies adjacent to the capital city, Muscat,
on the southern shore of the Gulf of Oman,
During the fall of 1987, a small area of the port
(less than 100 meters square) was dredged from a
depth of about 31h meters to a depth of 5 meters,
Clamshell dredges removed 7,000 cubic meters of
spoil which were transported by barge and dumped
in deep water clear of the port entrance.
The bottom was gray muddy silt overlying compacted gravel. It seemed unlikely that such unattractive and sometimes evil-smelling
material could pos-
sibly harbor any form of marine life. Close examination, however, ~howed .it was the ~raveyard of a
startling number and variety of marine mollusks,
many classified as "rare."
Most of the shells are in the local "bible" for
shell collectors - Seashells of Oman, by Donald
and Eloise Bosch (HSN June 1983). Some remarkable surprises were revealed when the location and
the number of each species we found was related to
the distribution
and rarity given in Bosch. Many

shells dredgedat Mina Qabooshad only been found
previously at Masirah Island, some 400 kilometers
down the coast, and some were "rare," even at
Masirah. Finds that gave particular pleasure were
Latirus bonnieae, named after the Bosch's daughter
Bonnie, and Harpa ventricosa - albeit only 67
As mentioned earlier, the area dredged was a
graveyard,and with only two exceptions- one of
which was a lovely Cypraea grayana of 75 mm -
millimeters!
The rarity values given in Bosch may need some
revision. For example, Conus generalis maldivus
were plentiful although describedas "uncommon"
at Masirah and "rare" at Muscat. The so called
"uncommon" Conus quercinus, Conus tessulatus
and C. betulinus were common, particularly C. betulinus.
Sizes of shells recovered were also interesting.
Those given in Bosch are the largestthey had found
at the time of going to press. Some of the shells
found at Mina Qaboos were records by that standard, notably a Conus terebra thomasi of 90 mm, a
Conus textile of 125 mm, a Ficus subintermedia of
87 mm, and the common Turritella cochlea of
105 mm.
Even more exciting were the shells (table 2) not
listed in Bosch. Donald Bosch and Kathleen Smythe
helped in identifying these shells. Most are in Doreen Sharabati's Red Sea Shells. These are an extensioninto the Gulf of Oman.
were in good condition, notably Conus betulinus
and C. quercinus; others were in poor shape,particularly Conus vexillum and C. terebra thomasi.
All cowries recoveredwere in poor condition except
one Cypraea annulus of 30 mm which might have
beencollected live.
I spent seventeen afternoons' 'trudging the
sludge" on the dredgebarge. The earlier days were
the most rewarding, since most shells were on or
near the surfaceof the original bottom. As dredging
got deeper, the number and variety of shells fell off
to almost zero.
The entire exercisewas intensely interesting, indeed exciting, as rare shell after rare shell was
found in a location where they were previously unrecorded. Although the quality of specimenswas
generally poor and - from a collector's point of
view disappointing- the knowledge acquiredadds
all shells recovered were dead. Many were filled
with cemented sand making interior cleaning difficult. The exterior condition varied - some cones

The Hawaiian Malacological Society awarded
cash prizes, certificates, and letters of commendation to eight junior and senior high school studentsat the 31st Hawaii StateScienceand Engineering Fair in Honolulu early in April. The money
came from a special fund establishedten years ago
by Mr. & Mrs. E. R. Cross.
The "big winner" was Phuoc Thieu Do, a
tenth-grade student at McKinley High School in
central Honolulu and a recent arrival from Southeast
Asia. His project was "Immunological and Biological Comparison of Toxic and Non-Toxic Shellfish," using samples of imported mollusks of
known toxicity.
To assurethe nontoxicity of his "control" shellfish (anotherbrand of imported meat), young Do ate
some himself. He felt no symptoms, he reported.
He received $50 in cash, plus an award certificate
and a letter of encouragementfrom the Society. A
comparableletter goes to his school and his teacher,
KatherineTaniguchi.
Cash awards also went to Jon Tokuhara ("The
Effect of Tidal Zones on Different-size Nerita
picea"), Deanna Akahoshi \'Micromolluscan
Assemblagesat Shallow Water Sites"), Randolph
Jose (' 'The Effects of Light Intensity on Photosynthesis in Plakobranchus ocellatus "), Daniel
Kurisu and PeterSeiokajointly ("Biological Control
ofCorbicula Clams"), and Janelle David and Ronlynn Sato jointly ("Does an Octopus have Fingerprints?").
Three of the winning studentswere invited to set
up their displays or make short reports on -thepr0jects at coming meetingsof the Society.

about 44 mm, are
found at elevations of about 6,000 feet near the
large town of La Trinidad.. central Benguet. [See
map HSN October 1987 p 13.]
The body of the snail is light brown throughout,

SHELL NEWS

Helicostyla montana is one of the smallestof the
mountain Helicostyla, averaging around 63 mm in
length. The body of the snail is slightly pebbled,
and is a light brown, darkening near the head. The
tentacles are medium brown, with lighter tips and
black eyes. The bodies of some snails are darker
than others; and, when this is the case, the shells
are also somewhatdarker.
Helicostyla montana is nearly always found in
isolated mountain areas and is seldom found near
population centers. It has been collected only in
mountains at about 8,000 feet in northern Benguet
and in Ifilgao provinces. In their mountain homes
the snails station themselveson large trees at about
15 to 20 feet, in clusters on both tree trunks and
lower branches.In a terrarium, the snails climb to
the highest possible point, affix themselvesthere.
and usually remain stationaryuntil they die.
The shell of H. montana is small, averaging
about 28 mm. The shells are more elongated and
rougher than the other mountain Helicostyla. The
usual color is light or medium brown, lighter on
top. Some varieties are solid brown; others are
marked with a single light brown band of hydrophanousperiostracumjust below the periphery; and
other forms are much more heavily marked with
hydrophanousperiostracumon the final whorl. The
outer lip and the outer edge of the white columella
are coveredwith dark brown.
12, ACHATINA FUUCA (BOWDlCH, 1822)
In size, A. fulica is almost equal to Helicobulinus vidali [HSN November 1987 p 7], averaging about 104 rom. A. fulica, however, is a wider
snail with foot widths up to 50 mm. Almost all of
the body is black, with only the tentaclesbeing dark
brown. The entire body is heavily grained,and there
are deep, oddly placed indentationsat the edge of
the wide, flat foot. About one week after birth, the
snail's body is medium gray, with lighter tentacles,
and are about sevenrom in length. The shell, which
is about five rom long is round, glassy and translucent, is coveredwith black and white spots.
Ackatina fulica was introduced into the Philippines in 1942, reputedly as a food supplementfor
the JapaneseArmy. Today, they can be found in
great quantities around populatedplaces throughout
the mountains of northern Luzon. They are not
known from higher elevationsbut are usually found

Roland Houart has chosento set up his home and
dedicate his leisure time to the study of Muricidae
in a peaceful and picturesquevillage north of Louvain, the famousUniversity town in Belgium.
As a teen-ager,after taking over a budding collection from his elder brother, he developed a keen
interest in mollusks. Muricidae appealed to him
more than any other family but, he soon ran into
identification problems. Houart realized that if he
wanted the right answers, he had to do in-depth
researchhimself.

Dr.
New Orleans,
one of the world's leading experts on muricids, put
it: . 'He labors among molluscs for the sheer joy of

An inspec-
tor of schools for the Belgian Ministry of Education,
Houart has a full time job, but one that leaves him
enough time to delve into the mysteries of maIacology as a dedicated amateur.
It took only a few years to assemble a vast and
comprehensive library
of reference literature pub-
lished on muricids. Houart became acquainted with
Dr. Emily

book on Murex classification.

[HSN April 1985], and since then they often work
on speciesin close cooperation.Houart also receives
fri~ndly support from professorBen Tursch (Universite Libre de Bruxelles) who worked in PapuaNew
Guinea for many years. Many other professional
malacologistsin the United States,Europeand Australia keep in touch also; Houart gratefully acknowledgesthem all.
Roland Houart is now a scientific collaborator to
the Royal Institute of Natural History of Belgium.
As such, he has accessto holotypessent on loan by
other museums. Collectors from all countries send
him study material, field observation data, and
many specimensfor identification. When an undescribed speciesturns up, more specimenshave to be
found; this can be difficult with deep water species.

Between 1979 and 1986 Houart described45 new
speciesand one genus, Ponderia. He describedhis
first Murex as Chicoreus subtilis in 1977 but, becauseDr. Shikamaof Japanhad describedthe same
species as Pterynotus orchidifloris
in 1973,
Houart's name cannot be used. Dr. Vokes says,
"Such are the perils of nomenclature."
A steadfastand dedicatedworker, Roland Houart
deservesour recognition and appreciation. He has
no time for other hobbies, no time for holidays. AIl
his trips abroadare to natural history museums.His
understandingwife patiently acceptsthe competition
of Muricidae in her husband'slife.
I once asked this prolific author whether he had
ever thought of compiling all his accumulated
knowledge into an easy reference book for lazy
collectors. With his natural gentlenessand genuine
modesty, Houart said. . . surely, surely he had
considered it! But not just yet, one day after he

laboratory, Aquarius. with living and sleeping quarters at a Sa-foot depth on the sea floor of the Salt
River Canyon off St. Croix, the US Virgin Islands.
It is about the size of a small recreation vehicle.
The main chamber has laboratory equipment, computers, sleeping quarters and a modern galley.
Scientists will be able to live and work nearly indefinitely
at the bottom of the sea as they conduct

I am a young shell collector and need help with
this delightful
hobby. Is there a listing of species
and other information that would assist me in learning more about the shells of this area? I would
appreciate any assistance that you can give me.

in the 5,000 to 6,000 foot range. In a terrarium A.
fulka, like H. vidali, are active, constantly searching for food, and eating everything available. In the
wild A. fulica are associatedwith a native vegetable, cayote/sayote(Sechium edule), feeding on the
leaves of the plant. When equal amounts of cayote
leaves, cabbage and lettuce are placed in a terrarium, the lettuce would disappearfirst, the cabbagesecond,and the cayote leaveslast. .Whenfood,
particularly pungent lettuce, was placed in the terrarium, A. fulica, as well as other species,converge
on the food container. This probably indicates that
terrestrials have a sense of smell. To provide the
snail with a senseof smell may be the function of
the smaller pair of tentacles.
The shell of a fully grown A. fulica is solid and
large, averagingabout 70 mm, but generally with an
unfinished lip. The cream color shell is heavily
marked with red-brown axial streakswhich is nearly
solid on the body whorl. The apertureis ovate and a
pearly gray-white within.
Helicostyla leucophaea subfenestrata is one of
the rarest of all Philippine terrestrials. The snail is
found only in remote areasat elevationsof 7,5(}{}to
8,500 feet in the mountains where the three provinces of Benguet, Ifugao and Mountain meet, and
never near population centers. A mountain climber
collected several H. leucophaea subfenestrata at
around 9,000 feet on Mt. Pulog, the highest peak in
Northern Luzon.
The snail bodies, which averageabout 67 mm in
length, are dark brown, with darker head and tentacles. The body is comparativelysmooth and evenly
grained. In its mountain abode,H. leucophaeasubfenestrata have been found living on parasitic
plants, which are living on pine trees. In a terrarium, the snails act like typical Helicostyla, climbing to the highestpoint of the tank and moving little
thereafter.
The shell of H. leucophaea subfenestrata is
solid, elongated,and nearly all brown. It is usually
covered with a heavy coating of lighter brown hydrophanous periostracum placed in axial streaks.
Some specimens are further decorated with light
brown bands of hydrophanousperiostracum. The
base is a shiny red-brown, and the white columella
and lip are edged with shiny brown. The aperture

interior is usually a milky white. H. leucophaea
subfenestrata is similar to, and is probably closely
related to, H. montana, but the animal of this terrestrial is always larger and darker and the shell is
always much larger than that of H. montana.

One cowry, found in Tonga three years ago, continued to defy identification [using Burgess, 1985,
Cowries of the World] even when all others had
found their niche. Gordon Verhoef, publisher of
Burgess' book, was here last week, and helped us
with the shell.
It most nearly fits the description of Cypraea
bernardi but has much finer teeth. Gordon feels that
it is a new species.So, it looks like Tonga will be

so, considering the great variability
of the latter and
the close resemblance of the two species. However,
when 1 kept finding both species living side by side
and could separate them without hesitation, I had to
give them a closer look.
Columbella dysoni differs from C. mercatoria in
the following
points: it is a smaller species (12 to
14 mm) than C. mercatoria (18 to 22 mm); it has a
higher spire in comparison to the total length of the
shell; it has 11 to 12 denticles on the outer lip

TROPICAL LANDSHELLS OF THE
WORLD.By Brian Parkinson, with Jens Hemmen

REVIEWED By ALLAN ffiNTON
"Landsnails have for too long been considered
the poor relatives of marine molluscs," notes HMS
member Brian Parkinsonin his foreword to Tropical Landshells of the World. "Those familiar with
the dull and inconspicuousspecies living in their
suburbangardens in temperateclimates are usually
unaware that in the great rain forests of the world
dwell many glorious snails that rival any marine
speciesin color, patternand sculpture.
'The rain forestsof the world are disappearingat
.
a horrendousrate, many thousandsof hectaresbeing
felled each day. Whole islands in the tropics have
been completely stripped of vegetation and all the
creaturesthat once dwelt there have gone forever.
Landsnailsare among the fauna most vulnerable to
loss of habitat. To give publicity to these animals
and the dangers facing them, books are urgently
neededand to fill a little of this gap this book was
written. "
Tropical Land Shells of the World contains
maps of the tropical zonesand variations of vegetation, with chapters dealing with the five major
zones. There are excellent color photographsof live
specimensand of their natural habitat and regional
and generalbibliographies.
The plates are grouped and indexed to permit the
reader a ready referenceto zoogeographicalzones,
and there is a comprehensivegeneral index in alphabetical order of species, subspecies,subgenera
and genera.
Because of the systematic presentation and the
clear par-excellenceof the colored illustrations, this
book will be invaluable to both the researching
taxonomist and to the amateur collector of these
often beautifully colored and sculpturedshells.
[The copy at the Bishop Museum in Honolulu, is
beautifully illustrated but poorly bound, The index
explanation is confusing since it refers to table
numbersinsteadof plate numbersand plate numbers
are used throughout the book. Incidentally, at least
three genera and seven speciesused by JamesBarnett in his HSN series, "Land Snails of the Mountains of Northern Luzon," are not mentionedin this
book. TB]
DISCLAIMER
The HSN does not want to give the impression
that it "validates" ANY newly proposedtaxon. It
merely reports that they are newly published. The
editors do not have time, inclination or knowledge
to voice an opinion as to their biological validity.
This shouldbe left up to specialistsin eachgroup.
