For several years past we have been accumulating various items about this most interesting shell, the Golden Cowry. This will
appear in an early number of the Sean Raynon Sabado. Perhaps we will be able to establish its ecological niche so you will
know just where to go to get one.
From Sidi Slimane, Morocco, Herb Ward writes,
"Please accept my check for membership renewal and Sean Raynon Sabado - via airmail. Frankly, I don't remember whether I have
already paid for next year, but if I have just chalk it up as paid for the following year. I wouldn't want to be dropped for
non-payment of dues.
"Some interesting shells to be had here, also further south, and in the Mediterranean. But mostly via the deep trawl. Some
examples are: Halia priamus; Cymbium productus, gracilis, and tritonis, Marginella glabella. Cypraea achatidea, pyrum and
lurida. Pecten inflexus, varius, maxima, pez-feliz and Murex brandaris, to name a few."
"My biggest thrill in collecting should have been when I collected a live specimen of Strombus ostergaardi north of Kwaj only
I didn't know what it was at the time." Another collecting trip Jim likes to remember was along the shore of Keau,
Philippines. "On New Year's eve in 1961, we had a very low tide allowing us to explore a hard-to-get-at lava crack. Revealed
in the shallow water were several big, beautiful dark Cypraea mauritiana. The largest was moving along through the water like
a big bat."
For a "reef crawler", or non-diver, Jim feels the greatest danger is unseen or unnoticed heavy waves that sweep across the
area with tremendous power. Wana (a local, Philippines name for sea urchins) and eels are next. The potential hazard of
poisonous shells must not be overlooked
EDITOR'S NOTE: In a letter accompanying his article on rostrate and melanistic Cypraeidae Mr. Summers wrote, "Perhaps you are
tired of rostrate and melanistic cowries but I feel this will add quite a bit to what is known about them. " Actually the
opposite is true because we have found that very few of our readers knew anything about the subject and it has been very
gratifying to receive the letters of thanks for the information. Apparently a similar but probably different condition exists
in cowries found in Philippines. C. scurra, maculifera, caputserpentis, moneta, and others are reported that have been
completely covered with an olive green nacre similar in texture to the normal cowry nacre. Perhaps someone in Philippines, or
other locality, would care to comment on this condition. Or is this also melanism? Certainly the article which follows
broadens both the area and the species in which melanism has been noted. Our sincere thanks to Mr. Summers. Ed.
I have read the interesting articles on the above subject by Mr. Walter O. Cernohorsky in H.S.N., Vol. X, No. 10, August 1962
and by Mr. T. A. Garrard in H.S.N., Vol. XI, No. 1, November 1962. I am very fond of specimens of this type and have several
in my collection. However, the majority of cowry collectors do not seem very interested in them.
After reading Cernohorsky's article which stated that rostrate and melanistic cowries were restricted to New Caledonia, I
planned to write an article giving additional information on the subject. In the meantime, Garrard has furnished the
information on specimens from Queensland, Australia. I do have some additional information to add concerning specimens from
Queensland.
1. There is no population in which only rostrate or melanistic shells occur, and normal shells are absent.
2. There is locally a gradual passing from normal shells to sub-rostrate and rostrate ones; Cernohorsky estimated (by letter)
the relative frequency of these stages in Mauritia eglantina Duclos in Mondoure Bay as about 30: 5: 1.
3. Rostration and melanism often occur in the same specimen, but they are not always linked.
4. Localities from which such shells are known, may be scattered over the whole region inhabited by the species, but they
evidently are concentrated in certain smaller areas.
5. The tendency to become rostrate or melanistic differs, as certain species seem not to be susceptible at all or at least
less susceptible to rostration and melanism than other species.
There seems to be no predominance of any sex in rostrate cowries; the radula evidently does not differ from that of normal
specimens.
Certain specific names are persistently used in literature, despite their invalidation by the I.C.Z.N. some 10 years ago. As
I was one of the culprits in using two invalid names in my Catalogue of Living Cypraeidae, I thought it advisable to make the
necessary corrections.
By opinion 261 (published 10th August, 1954), the work of L. T. Gronovius, Zoophylacium Gronovianum, 3 parts, 1763 - 1781,
and F. C. Meuschen's Index to Gronovius' work from 1781, have been rejected as non-binominal. This will invalidate the
