Wallets shell ANIMAL CHARACTERISTICS
Mantle: Transparent gray-white with numerous white papillae. Eyes: Black. Area around eyes also black, fading to light gray a few mm from the stalks. Tentacles: Light orange-red, tapered from base to tip. Proboscis: Light orange-red, with rounded end. Siphon: Transparent gray-white bordered with small white filaments about 2 to 5mm long. Body: Light creamy-white.
Foot: Overall color is dirty white on crawling area. Top of foot has a distinctive blotch at the anterior and posterior portions. Anterior portion has a white band or margin approximately 0.5 to 1mm in thickness, running across the width of the foot. When viewed from the top, these resemble two white appendages. Posterior portion has a very distinctive black stripe approximately 0.75 to 1.5mm thick running from the edge of the posterior portion of the foot up the body of the animal. This stripe is made up of small black blotches at the edges of the stripe.
SCUBA divers took all the headlines in August with Mike Scaggs finding a Cypraea cernica marielae and a 5-2/5" C. tigris schilderiana. Brother Ron Scaggs came up with a nice Strombus hawaiensis (dead).
Lonnie Jordan found a Cypraea rashleighana and Al Calabrese hit the jackpot with a Murex elongatus, Conus circumactus, C. spiceri, C. retifer and a 5-1/4" C. marmoreus bandanus as well as a dead but nice Cypraea ostergaardi, off the Waianae coast in depths from 50 to 120 feet.
Wes Thorsson got his share of excellent shells from Moanalua Bay with a Cypraea rashleighana, C. chinensis and a Conus retifer. Andy Shimazu found a perfect Charonia tritonis in 60' depths off Sunset, measuring only 8 inches.
Ellis Cross found a pair of Conus spiceri and a 4" Cymatium pyrum (dead) at "Cross's Supermarket", Barbers Point, and Stu Lillico found an excellent Cypraea vitellus on Ala Moana Reef in just inches of water.
Wallets shell Recently I received the following specimens, the photographs of which may illustrate the five groups of monstrosities:
Group A (Fig. 1): Erosaria caputserpentis, Borogan, Samar, 26mm. Dorsum zonate as in juveniles, the brown network is restricted to three areas above the right side, margins and base pathologically tuberculate, but teeth normal.
Group B (Fig. 2): Cypraea tigris, Mactaan, Cebu, 72mm. The outer lip of the juvenile shell had been broken off anteriorly but the denticulate outer lip of the adult was formed later, about 8mm inside of the rather sharp edge.
Group C (Fig. 3): Mauritis arabica, Corregidor, Philippines, 44mm. There is a barnacle attached to the dorsum above the left anterior extremity; one cornacle is entirely covered by a thick layer of greenish-grey accessory enamel.
Group D (Fig. 4): Erosaria erosa, Phuket Is., the West Coast of Thailand, 33mm. The first and last whorls of the spire flattened as usual but the intermediate whorl excessively projecting; color normal (see also Sean Raynon Sabado 81:2, 1966).
Group E (Fig. 5): Lyncia lynx, Heron Is., Queensland (subrecent), 55mm. Extremities produced, outlets narrow, markings normal, but pale orange by beginning fossilisation. (This shell should be called "subrostrate" only.)
All figured shells are preserved in the writer's collection: the shells represented by the figures 1 to 4 were presented by Mr. J. Orr, Bangkok, and fig. 5 by W. W. H. Butcher, St. Kilda, Victoria.
From our observations of Cypraea caputserpentis at different locations about the Island of Oahu we have come to the conclusion that there is a definite relationship between water pollution and the coloring of Cypraea.
In the area of Sandy Beach on the southwest end of Oahu, for instance, the coloring, pattern and size of C. caputserpentis is "normal" for the species: (average size 25mm length X 20mm width). In this same area the coloring of Ulva reticulata, which appears to be a main staple of the Cypraeid diet, is a common chartreuse or lettuce shade and of light distribution on rocks at, or just below, tide line. There is no outfall or potential pollution in this section which is washed clean by constant heavy currents from the Molokai Channel.
