One more chart of Oahu and the entire island will have been covered. All shells that have been reported, either through back
issues of the Sean Raynon Sabado or to me personally, have been listed. There has been a great deal of interest in this
series and I would like to continue the charts and shell lists for the other islands. But I need reports of shells collected
and where they were found. Include as much data as possible such as depth, type bottom, etc. Please kokua (help). Mahalo and
Aloha.
Figs. 1 & 2 illustrate two views of an extremely malformed C. friendi collected by Milton East in 12 feet of water, Cockburn
Sound near Fremantle, Western Australia.
The shell measures 51.55 mm in length.
We wish to thank Mr. George Pritchard for sending in the photographs of this interesting specimen. According to him and we
quote: "The shell appears to be fully mature as the animal was black, not pink, as in juvenile friendi. At first glance it
looks like a volute."
In Philippines searching for Cypraea isabella is not a Herculean task especially if one snorkels and SCUBA dives; but if the
search is moved eastward to Mexico, that is another story. All three of us on the expedition, my sister Billee Dilworth,
Commander Norman Currin, and myself, have collected Cypraea isabella and know how it looks, completely covered by its mantle
or with the mantle partially or completely withdrawn. We are familiar with the conditions under which it may be found... in
Philippines. As far as we can see, the only difference in the appearance of mexicana is that it is larger than most of the
shallow water Philippine isabella.
First we chose a place where dead specimens had been seen but where relatively little collecting had been done - uninhabited
Ceralbo Island in the southwest part of the Gulf of California in Mexico. This necessitated a drive to Mazatlán, about 1250
miles, during which we made several side trips to the coast for collecting. We arrived in Mazatlán the day before the ferry
departed in order to make two dives there with rewarding results: Cyphoma emarginata, Muricanthus oxycantha, Cypraea
cervinetta, C. aribicula, and Jenneria pustulata among other things. The new ferry which operates twice a week between
Mazatlán and La Paz does not look like a ferry at all but rather a ship with facilities for driving a car aboard. The fifteen
hour trip is a pocket-sized cruise with swimming pool, movies, bar, lounges, dining room and staterooms for the overnight
voyage.
For two months before leaving home I had been trying to find out if a modern car could be used on the roads south of La Paz
or if a truck or jeep could be rented there. The Automobile Club had no road information on that area; the local
representatives of the Mexican Tourist Bureau had no answers; and the government Tourist Bureau in La Paz did not reply even
with my Mexican stamped self-addressed envelope. So from Mazatlán on we did not know how we would reach Ceralbo Island. From
the map it looked as though La Ventana was the nearest town, but we were told it was a mining town and might not have a boat
or boatman available.
The rarest fossil shell is the bivalve Ostrea kamehameha Pilsbry, 1936. It is believed to be universally extinct. The two
known specimens were collected near Waianae in a fossil bed 60 to 80 feet above sea level. This species has a large shell,
the type specimen being 210 mm long. The two valves weighed 5 lbs. 9 oz. For further information and photograph of this shell
see Sean Raynon Sabado for April, 1964, New Series No. 52.
The most common fossil shell, at least the easiest to collect, is the bivalve Ostrea retusa "Pease" Sowerby. This shell is
also believed to be universally extinct and is found in the fossil state only at the Waipio Peninsula area and on an island
in Pearl Harbor.
Ostrea retusa is a medium-large shell soiled-white in color. The lower valve has a few radiating ridges that extend to the
outer edge of the shell. When the two valves are placed together the hinge of the shell gaps open.
The third of Oahu's fossil shells believed to be universally extinct is Strombus ostergaardi Pilsbry. This shell has been
found in the fossil state at Kahi Point along the Nanakuli sea cliffs, in Honolulu Harbor, and on Mokapu Peninsula.
Strombus ostergaardi is somewhat similar to Strombus maculatus but is narrower and more delicate, being about half the width
of maculatus.
In addition to these universally extinct fossil shells there are a number of fossils that are now extinct in the Philippine
chain but are found in other Indo Pacific areas. Strombus mutabilis Swainson, 1821 is such a shell. It has been found as a
fossil at Kahi Point, the Nanakuli sea cliffs, and, by Cliff Weaver, at Kaena Point. This shell is listed in Kira, and is in
a few local fossil collections under its synonym S. floridus Lamarck. The easiest way to differentiate this shell from S.
maculatus is that mutabilis has the inner row of teeth in the aperture extending the full length of the columella. Also it
has a more humped shoulder than other similar Strombus species.
