INVERTEBRATE ANIMALS OF VINEYARD S )UND, ETC. G97 



Sable, 8 fathoms. Not observed on the eastern part of the coast of 

 Maine, nor in the Bay of Fundy. Very common in Long Island Sound, 

 Buzzard's Bay, Vineyard Sound; along both shores of Long Island; 

 New Jersey, and southward ; low-water to 12 fathoms. Southern part 

 of Saint George's Bank, 20 fathoms, (S. I. Smith). 



Fossil in the Post-Pliocene of North and South Carolina; and in the 

 Pliocene of South Carolina. 



Linne gave " Pennsylvania " as one of the localities for his A. epliippi- 

 um, and, therefore, probably confounded our shell with the European 

 species, as most subsequent writers have done. Gould has well described 

 our species in its different states, under the names quoted above, fig- 

 ures 499 of the second edition (our figures 241,242), represent the ordi- 

 nary adult form, which is everywhere abundant on the southern shores 

 of New England. The specimens from Eastport, Maine, referred to A. 

 ephippium by Gould, were undoubtedly the smooth or squamose variety 

 of the following species.

 498. 



Long Island to Labrador, and northern coasts of Europe. Off Ston- 

 ington, Connecticut, 4 to 5 fathoms rocky ; off Gay Head, 10 fathoms, 

 scarce ; very common in Casco Bay, Bay of Fundy, and northward, low- 

 water to 80 fathoms. Greenport andMontauk, Long Island (S. Smith). 



Varieties of this species occur frequently in the Bay of Fundy and 

 Casco Bay, in which the aculeate scales are more or less abortive, or 

 even entirely absent, leaving the surface either nearly smooth or irregu- 

 larly squamose, but such varieties are easily distinguished from the 

 young of the preceding species. 



This may possibly be a variety of the true epMppium of Europe, as 

 supposed by many writers, but 1 believe it to be perfectly distinct from. 

 A. glabra.

 southern part of the Gulf of Saint Lawrence, at Prince Edward 

 Island, in Northumberland Straits, and Bay of Chaleur. Not found 

 along the eastern shores of Maine, nor in the Bay of Fundy. Abundant
