NORTHERN ZOOLOGY. 



no lustre. Were these scales to become tumid they would assume the granulated appear- 

 ance noticed in the account, of the Bathurst Inlet fish. The top of the head is covered 

 with smooth skin on which there are many black specks. The pectorals almost touch below, 

 and include an acutely elliptical space between their origins and the gill-openings. The anal 

 is attached to a compressed, acute, and somewhat projecting portion of the tail. In other 

 respects the description of the Bathurst Inlet fish applies exactly to those from Newfoundland. 

 The rays vary in different specimens, as may be observed in the following table.

In all, the last ray of the dorsal is divided to the base, and that of the anal nearly so. The 

 caudal is much forked.
