Robert Bell, Jr. (Canadian Naturalist and Geologist, iv, p. 210, 

 1859) records "a specimen corresponding nearly with Bell's descrip- 

 tion" of Crangon sculptus, from off Cape Chatte, Gulf of St. Lawrence, 

 but was probably mistaken in the identification of the species, having 

 had most likely Crangon boreas, or perhaps one of the species of 

 Sabinea.

Two distinct species have been confounded under the name septem- 

 carinata. In one of these the rostrum as seen from above is short 

 and obtusely rounded at the tip, and the extremity of the telson is 

 subtruncate and armed with a series of eight or more spines or stout 

 setae ; in the other species the rostrum is acutely pointed and the 

 telson terminates in an acute tip, with one or two spines each side. 

 Sabine's original description and figures show very plainly that he 

 had the first of these species, and to this species also Kroyer's figures 

 and descriptions, above referred to, apply. I have, however, received, 

 from Professor G. O. Sars of Christiania, both species under the name
