THE NAUTILUS. delesy 
Cassis cameo Stimp. One sea-worn specimen on the ocean beach. 
Semicassis sulcosus Brug. var. inflata Shaw. Rare. 
Dolium galea Linn. Several broken shells. D. perdix is not 
found here. 
Pyrula papyratia Say. A few sea-worn specimens. 
Natica pusilla Say. Common. 
Natiea duplicata Say. Common. 
Sigaretus perspectivus Say. Not common. 
Sigaretus maculataSay. Rare. I believe that this is identical with 
S. Martinianus Phill., of the West Indies. The only apparent 
difference is that the revolving brown bands of S. martinianus are 
irregularly divided into maculations by broad longitudinal lines 
which usually represent rest periods in the growth of the shell and 
are frequently on S. martinianus. 
Pyramidella conica C. B. Ad. Several specimens. 
Littorina irrorata Say. Common. 
Littoria seabra L. var. lineata Gmel. Common on the sea wall 
but much smaller than those from the southern part of the State. 
Cerithium atratum Born. Common around Marsh Island. 
Cerithidea scalariformis Say. Common along the marshes west of 
the city. 
Cerithiopsis greenii C. B. Ad. Common. 
Cerithiopsis terebralis C. B. Ad. Common. 
Triforis nigrocinctus C. B. Ad. Common.

A WORD TO YOUNG COLLECTORS. 
BY JOSIAH KEEP. 
We ought to feel a great veneration for the men who have gone 
before us, and who spent so much time and strength in preparing 
the way for those who were to follow. Whenever we take up the 
label of a shell and see the abbreviation “ Linn.” following the specific 
name, how it carries our thoughts back to the great Swedish natu- 
ralist who did so much to simplify the nomenclature and enlarge the 
domain of science.
