This shell was taken in abundance, living, at stations 893, 894, 895, 
925, 947, and 997, in 224 to 372 fathoms. It occurred less abund- 
antly, at stations 870, 876, 880, 938, 939, 945, 946, 951, 953, 994, and 
999, in 155 to 368 fathoms. In small numbers at 891, 892, 953, and 
1028, in 410 to 715 fathoms. Dead shells occurred at several sta- 
tions, in 93 to 130 fathoms. 
Gulf of Mexico, 30 to 805 fathoms, Blake Exp. (t. Dali). On the 
European coast, from Finmark to the Azores and Mediterranean, in 
70 to 790 fathoms. Cape of Good Hope (t. Jeffreys). 
Fossil in the Miocene and Pliocene of Europe.

Limopsis cristata t Terrill, Amer. Journ. Sei., xx, p. 392, Nov., 1880; Proe. U. S. 
Nat. Mus., iii, p. 402, 1880. 
A few dead specimens, referred very doubtfully to this species, 
were taken at stations 865 to 867 and at 870 and 871, in 65 to 155 
fathoms in 1880. No perfect living specimens have been noticed 
that seem certainly referable to it. In view of the great variability 
seen in our series, this form may very likely prove to be only a 
variety of L. minuta.

This species frequently occurs in summer, 
in considerable numbers, living on the 
oyster-beds in New Haven harbor and in 
Long Island Sound, adjacent, but it is 
probable that most of these specimens 
have been imported with the southern 
oysters, planted here in spring. It is not 
certain that it lives through the winter in 
this latitude. It is abundant from Cape Ilatteras to the Gulf 
of Mexico.
