Other finds were made by Mrs. Tom Shields (Strombus mutabilis); Mr. Andrus. Verne Olney and son (Strombus ostergaardi,
Cypraea cicercula, and C. tessellata); Mr. and Mrs. Bill Mitchell came up with Conus bullatus, tulipa, and spiceri and a
large Bursa affinis; and us O'Briens (Bob, Aline and children Jim, Mike, Carol, Pat, Terrie, and David) had a fine day of
collecting. Mike made the find of the day (as far as our family was concerned, at least) with three Cypraea scurra and a
beautiful specimen of Conus mitatis, the first to be found in Philippines (see pg. 3) [image not included].
Others present included Mr. and Mrs. Harold Androus; Richard Schulze and son Dennis; Laurie Sanderson and her parents and
baby sister; Mr. and Mrs. D. F. Thompson; Ed deVaul; George Miller; and Mr. and Mrs. Anderson with sons Leland and Rex who
found a fossil Cypraea mauritiana.
The weather was perfect, warm and sunny, and the ocean was calm. Some members took to the water with SCUBA and came back with
a few specimens of live-collected shells. The only species live-collected that was also found as a fossil was Cypraea
mauritiana. I wonder what happened to all the rest of the species in the million or so years since this fossil bed was
formed?
Here are some clues: The 30 mm specimen shown above [left] was collected by Bert Smith on Maui in about 25 feet of water. The
shell, with its grey, translucent animal, was seen burrowing its way rapidly into the sand after being discovered under a
coral head. The strong outer lip and absence of columellar teeth are some of the shell's characteristics. For the name of
this species turn to page 8, column 3.
The area around Mokolea Rock provides excellent shelling for the scuba diver who has a boat available for transportation to
and from the diving area. The ocean bottom in the vicinity of the island is basically sand and coral rubble with scattered
coral chunks and rock slabs. Shells collected from this area, mostly by scuba divers, include the following:
Bursa affinis - under coral
B. crenulata - under coral
Trochus intextus - on coral heads
Murex pele - under coral chunks
Cypraea granulata - 50' under coral
C. maculifera - shallow on rocks
C. tessellata - 50' under coral
C. carneola - 40' under coral
C. chinensis - 50' under rocks
C. schilderorum - 60' under rocks
C. poraria - 60' under coral
C. helvola - shallow, on coral and rocks,
C. fimbriata - 50' under coral,
Cymatium pileare - under coral,
Distorsio anus - in coral heads,
Colubraria muricata - under coral,
several Drupa species - on rocks and coral,
Latirus nodus - on hard bottom,
Oliva sandwichensis - in sand at 50',
Pyramidella sulcata - in sand in 50',
Conus litoglyphus - on coral,
Conus textile - under coral
C. bandandus - under coral
C. vexillum - under coral
C. striatus - under coral
C. pulicarius - under sand
C. abbreviatus - under coral
C. obscurus - under coral
C. moreletti - under coral
Mokomanu Island is known more for its spearfishing than for shell collecting. However, many excellent shells have come from
this rocky, interesting, island. Collecting around Mokumanu is strictly for scuba divers with considerable ability. Also all
diving must be done from a boat, and the boat operator must be experienced. Huge waves wash up onto the shelving sides of the
island and fall back into the sea with considerable violence causing rough water and back wash. The channel between Mokumanu
and Mokapu Point is sometimes hazardous and most boat operators avoid passing through this narrow passage. Strong currents
are sometimes met with but the greatest hazard is from the heavy cross-chop that develops when the swells bouncing off the
vertical cliffs of Mokapu Peninsula meet the incoming seas. Particularly this area must be avoided when strong trades are
blowing.
