THE NAUTILUS. 67 
A NEW GASTROPOD FROM NEW JERSEY.! 
BY H. A. PILSBRY. 
At the regular weekly meeting of the Academy of Natural Scien- 
ces of Philadelphia, October 18, 1892, Mr. H. A. Pilsbry exhibited 
a series of specimens of a large species of Chiysodomus, belonging 
to the subgenus Sipho, which he had received from Messrs Witmer 
Stone, Chas. LeRoy Wheeler and John Ford. He stated that the 
specimens were cast upon the shore during severe gales from the 
south east, and were evidently derived from a submarine stratum 
which was disturbed and broken up at those times. Associated with 
the Chrysodomus were examples of Buccinum undatum, Urosalpinx 
cinereus of extraordinary dimensions, and Chrysodomus (Sipho) 
Stimpsonii, the latter being well developed and typical in sculpture- 
The age of the deposit cannot be definitely settled at present, but 
the evidence at hand indicates that it is post-pliocene. 
The following description of the new species was offered : 
Curysopomus (S1pHo) Sroner (Pl. Il, figs. 1, 2, 3,). Shell 
obese-fusiform, rather thick and solid, with strongly convex whorls 
separated by deep sutures. Sculpture consisting of strong spiral 
cords, equal on young specimens and on the spires of adults, but 
which alternate with smaller intermediate cords on the body-whorl 
in full grown specimens. A young shell therefore has about 20, an 
adult 40 spirals upon the body-whorl. The aperture is oval: the 
canal is strongly curved to the left and backward. 
Length 72, greatest diam. 45 mm.; length of aperture and canal 
51mm. The largest individual measures, length 100, breadth 64, 
length of aperture 73 mm. Both of these, as well as all specimens 
seen, have lost several of the earlier whorls; so the length of a 
perfect individual would be proportionately greater. 
The more prominent features of this species.are the swollen form, 
deep sutures, the strong spiral sculpture, and the strongly recurved 
canal. 
The localities whence specimens have been obtained are as 
follows: Point Pleasant, N. J. (Witmer Stone); Sea Isle City, N. 
J. (John Ford, Oct., 1892); Cape May, N. J. (C. LeRoy Wheeler, 
1891.) 
Prof. A. E. Verrill of Yale College very kindly compared spec- 
imens of this species with the collection under his charge (a collec- 
tion vastly richer than any other in mollusks of the north-west 
Atlantic.) He writes as follows: 
“T have made a careful comparison of the Sipho sent by you with 
our series.
