56 NORTHERN ZOOLOGY. 



between the pectorals and gill-openings, having the form of a piece of Greek money. 

 It has thirty-one vertebrae and the same number of lateral scales. The four dorsal 

 spines are serrated. The Kamtschatdales collect it to serve as food for their dogs, 

 and they also prepare excellent white soup with it for themselves. 

 G. Noveboracensis is, as the name indicates, a New York species. 



It has a very strong resemblance to the G. trachurus, its most obvious peculiarities being 

 the narrow dorsal plates, the more prominent keels of the tail, and the position of the lateral 

 line, which is nearer to the back.

This species, which has also an armed tail, inhabits Newfoundland. It has a 

 more elongated form, and more slender spines than its European representative. 

 Its lateral scales amount to thirty-three, and its colour throughout is blackish.

This Stickleback is said, by Dr. Mitchill, to inhabit the salt waters of New 

 York, and to consort with the Killifish, or Cyprinodons. M. Pilaye sent it from 

 Newfoundland to Cuvier. It is one of the smallest of the genus, Dr. Mitchill 

 assigning it a length of scarcely an inch, and the Newfoundland specimen mea- 

 suring only seventeen lines. 



It is distinguished from the other species by a sharp flat tooth on the external base of each 

 ventral spine, the European species having simply an enlargement there. Notwithstanding 

 its name, it has three dorsal spines, the third being small and joined to the soft dorsal.
