in length between five and six inches : it is the same fish, of which an individual 
was brought home by the former Expedition, and was named by Dr. Leach. 
This species is very nearly allied to the Gadus Virens of authors, from which, 
however, it may be distinguished by the third dorsal fin being larger than the 
two anterior, whereas in the Virens the middle one is the largest : the lower 
jaw also rather exceeds the upper; the tail is slightly forked. — D. 14*, 16, 19.

Merlangus ? 
Three individuals, fifteen inches in length, of a species of Merlangus, were 
found in the ice which covered the harbour in which the ships wintered ; 
they were frozen in the ice near its surface, and it was supposed must have 
been dead on the water when the frost set in ; they were so much decayed 
that it was not possible to identify the species. The lower jaw was ob- 
served to exceed the upper a very little ; both jaws were armed with teeth, 
the hinder ones of the lower jaw being tricuspidate ; it could not be de- 
termined whether the species is cirrated. — P. 18. V. 6. D. 13, 19, 20.

Liparis Communis. 
Several individuals were taken in the trawl on the west coast of Davis’ 
Strait, in latitude 70 degrees. They differed in no respect from the unctuous 
Sucker of our coasts. 
Blennius Polaris. 
B. imberbis, pinnis anali, caudali, dorsalique, unitis. 
The individual here described was found on the shore of North Georgia, ' 
where it had been left by the ebb tide, in September 1819, It bears a very 
near resemblance to the description and figure of the B. Viviparus, in Muller's
