Fusos calus
It should be the Malacological trend to consolidate nomenclature and not separate, and separation should be done only if the
characteristics of the new species or subspecies are constant in large series (not 16 shells) of shells, and peculiar to the
new subspecies only. This does not apply at all in the case of C. chinensis amiges and the situation of tagging a new name to
every ecological variation, is getting ridiculous. I am convinced that my article will not stop Mr. Cate from naming another
dozen new subspecies before giving up his malacological hobby, however, it is only fair, that if we have to read Cate's
inconclusive arguments in favor of his new subspecies, we should be permitted to express our own arguments against accepting
his new subspecies. Furthermore, it stimulates scientific thinking, and will show to Mr. Cate that we do not accept every
subspecies he dishes out from his conveyor belt.
In The Veliger, Vol. 5, No. 2, pp. 74 77, Crawford Cate made an attempt to restore the old subspecific name amiges to current
usage. It is unfortunate that he based his differentiating comparison on specimens from the Philippines only, and did not
take into account specimens of C. chinensis (which the Schilders call C. chinensis variolaria Lamarck, 1810) from Mauritius.
The morphological relationship, despite the greater distance from Philippines, is closer by far between variolaria
(Mauritius) and amiges (Philippines), then it is between C. chinensis, sensu stricto (Philippines) and amiges.
As Crawford Cate pointed out in his article, Melvill & Standen's specimen of amiges was a single, dead shell of unknown
locality. Melvill and Standen's contention that amiges could have come from the Philippines Archipelago was a mere
presumption and by no means zoogeographical reasoning, for the specimen could have just as well come from Mauritius. Once the
locality of a holotype of a species or subspecies is unknown, it is useless to guess where its origin might have been.
The Schilders in their nomenclatural system accept (4) races or subspecies of C. chinensis, which are as follows: C.
chinensis chinensis Gmelin, 1791, (32/61, 17:16). C. chinensis violacea Rous, 1905 (31/63, 15:15), C. chinensis variolaria
Lamarck, 1810 (32/64, 15.16), and C. chinensis sydneyensis Schilder & Schilder, 1938 (35/63, 15:14). The figures in brackets
signify the following: Length in mm., width as a % of length, mean number of labial teeth as reduced to a shell 25mm. in
length: mean number of columellar teeth also reduced (see Schilder, Zool. Anz. Bd. 92, H. 3/4, 1930). The Schilders'
statistical figures were obtained by personally examining 250 specimens of C. chinensis from different localities.
Getting the live Lima scabra was quite an experience, too. They were back in holes in a rock wall and under small loose
rocks. We held on to the larger rocks, with our feet on a little ledge that dropped off to 20 feet or more. Neither Mary nor
I are good enough swimmers to venture in water over our heads but we sort of forgot about that as we saw the red and white
tentacles waving about. We'd reach for the shell which would snap shut and retreat in the rocks. Some were attached by a
byssus and some were free swimming. We were both pretty leery of reaching in after it so if it got more than a couple of
inches back, we thought of moray eels and what have you, left that one and looked for one easier to get.
It was very warm and we think we'll plan future trips for cooler weather. Still, if we hadn't gone this summer, we might not
have gotten the Cyphoma and Lima.
P. S. Our Fort Myers Shell Club was organized in November 1962 and has 36 members. Mary Hartman mentioned above is secretary
and I am president. We have a very congenial group and are enjoying the club very much.
