THE - CONCHOLOGISTS’ - EXCHANGE. 
NECROLOGY. 
Joseph Wilson, M. D., U.S. N., died March 
Ist, 1887, aged 40 years. Dr. Wilson was 
connected with Perry’s expedition to Japan, and 
was much interested in Natural History. He 
also made many contributions to the Cabinet of | 
the Academy of Natural Sciences of Phila. 
He was the author of a work entitled “ Naval 
Hygiene,” published in 1879, a book of much 
merit. 
Dr. J. C. McCormick, Conchologist and 
Archeologist, of Strawberry Plains, Tenn., 
was killed on the 4th of Oct.,1887, by the col- 
lapse of an Indian mound which he was ex- 
ploring. 
VALVES. 
About 300 species of cowry (Cyfrea) are 
found in tropical and sub-tropical seas. 
Ovulum ( Volva) secale, Sowerby, a native of 
the Bahamas, feeds upon the polyps of Pero- 
gorgia setosa, Linn. 
The type specimen of Aulimus Rossitert, 
Brazier, New Caledonia, is deposited in the 
Cabinet of the Academy of Natural Sciences, 
Philadelphia.

line from top, please read coves for caves; and 
on 27th line, 2d column, the word venezws 
should be read instead of revives. ;

The British Government levies a tax of £2 
or $10 upon each specimen of Cyprea auran- 
fiw, Mtn., obtained for export. This accounts 
for the high prices at which this fine shell is 
held. 
Owing to the brittleness of Phastanella bult- 
motes, Lamarck, (a highly polished and very 
beautiful Australian shell related to 77ochus), 
it is very difficult to obtain perfect specimens. 
Mr. E. W. Roper, of Revere, Mass., upon a 
recent visit to Bethel, Me., reports that he found 
Planogyra asteriscus, (originally discovered 
there by Mr. Edward S. Morse, of Salem, 
Mass.), Hyalina ferrea, exigua, chersina, and 
lineata, Vitrina, limpida; Carychium exig- 
uum, Vertigo Gould, and simplex; Pupa 
fentodon and others. He found all these shells 
in the same kind of localities as Mr. Morse 
described 25 years ago. At Portland, Me., he 
reports having found the minute Seea pla- 
norbis, Rissoa occulens and Purpura lapillus. 
The following extract from Prof. Keep’s in- 
| teresting ‘‘West Coast Shells,” is a true index 
of the prevailing style: ‘At length I struck 
“upon a spot where a little stream of water was 
“oozing out from the bank of sand. As I 
“scraped away the surface, | saw something. 
“which would have made me dance for joy 
“had I not been weighed down by the long 
“boots. For there, in very truth, was a live 
“Olive, ( Ofivella biplicata, Sby.), with its grace- 
“ful shell shaped like Figure 20, and a beauti- 
“ful pearl-colored body. It quickly withdrew 
“this into the shell and closed the aperture 
“with a very insignificant scale, which seemed 
“*to be an apology for an operculum.”
