Their owners all are dead ; 
The mighty ships that brought them rot on shore ; 
Yet still that murmur lingers at their core, 
And Fancy’s light across their tropic bed 
Is shed. 
OUR NEW CATALOGUE OF MOLLUSCA. 
Last October we issued a catalogue of shells of 
120 pages, illustrated with 86 photo-engravings, 
depicting the more important families. 
This catalogue is by no means a mere price list 
of shells and alcholic mollusca; but contains 
much reading matter both of scientific and gen- 
eral interest. 
The species listed are all arranged after the most 
modern method of classification. 
The sub-kingdom is characterized in a page of 
description, compiled from the best and most re- 
cent writings on the subject; then follow more or 
less extensive descriptions, as their importance or 
peculiarities demand, of the classes, sub-classes, 
orders, sub-orders, families, sub-families, genera 
and not unfrequently even of species. 
The aim has everywhere been to make use of 
the latest and most approved nonmenclature, 
classification and characterizations. For this pur- 
pose much use has been made of Tryon’s “Struc- 
tural and Systematic Conchology,” Woodward’s 
“Manual” and Huxley’s anatomical works. With 
few and unimportant exceptions all families of the 
mollusca are represented. The type-species usu- 
ally heads the series except in cases of long lists of 
species, which, for greater convenience of refer- 
ence, have been arranged alphabetically. 
An important feature is the Glossary, giv- 
ing the derivation of nearly 2,000 Generic and 
Specific names. 
In addition to this there is a supplement enumer- 
ating about 500 species received too late for em- 
bodiment in the systematic catalogue. This has 
been thrown together in alphabetic order, as being 
the most easy for reference. 
The catalogue at the date of its issue, October 
15, 1885, included nothing that we did not then 
have on hand. Since then our stock has received 
severaHmportant, and many minor, additions, so 
that it is now larger than when the catalogue was 
issued, although, of course, some few species 
noted are not now on hand. 
ADDITIONS TO STOCK. 
The most notable addition to our stock since 
issuing the catalogue is a fine series of shells from 
the West Indies of the families Cyclostomidse and 
Helicinidse. In the former family of those whose 
chief habitat is the West Indies, our series em- 
braces the genera Ctenopoma, Choanopoma, 
Chondropoma, Cistula and Tudora. 
Of Helicinidse we have a splendid series of 
specimens of the genera Helicina, Trochatella and 
the smaller germs Proserpina. We have not yet 
catalogued these, but a manuscript list of them 
will be sent to anyone wishing to purchase.

IMPORTANT SHELLS. 
In our collection, of those which are particu 
larly worth noticing for their rairity or peculiarly 
perfect condition, we beg to call attention to the 
following: 
Spondylus pictorum. 
We have lately received a fine lot of this mag- 
nigcent shell, ranging in size from four to eight 
inches in extreme width and varying in color 
from pure white through delicate pink, orange, 
the various shades of red to deep purple. These 
are all fresh, live specimens and are in very fine 
condition. 
Pluronectia japonica. 
This remarkable member of the Pectens, with 
differerently colored valves, one highly colored, 
the other white, we have represented by large 
perfect shells. 
Lingula anatina. 
We have this shell in alchol with the muscular 
peduncle entire and attached. This genus is in- 
tereresting as being one of the oldest known 
forms of organic life. The genus is found fossil 
in the Lower Silurian. 
Guilfordia triumphvans. 
One of the most wonderful of the Imperators, 
with its extremely flattened form, carinated body- 
whorl extending into from 5 to 8 spines nearly 
three inches long. 
Murex senegalensis calcar. 
This is a rare Japanese Murex now for the first 
time offered to American collectors. 
Ranella pulchra. 
In this species the Ranella form reaches its 
extreme development, the lateral varices being so 
much extended that the width of the shell exceeds 
itsjthickness in the ratio of 4 to 1.
