Natural History of the Hudson's Bay Territories. 55 



have been accidental, or it may have been there for breeding 

 purposes, many sea ducks having recourse to fresh-water 

 lakes for this purpose. A circumstance of greater interest, 

 however, is, that it is not the common eider, but the Kams- 

 katchan species Somateria V. nigrum, distinguished by a 

 black mark in the shape of the letter V under the chin, and it 

 is the first time that this species has been recorded as being 

 taken east of the Rocky Mountains. Its occurrence in Great 

 Slave Lake certainly does not necessarily imply that it is to 

 be found in Hudson's Bay and the east coast, but it may be 

 so, and I would direct the attention of my friends there to it. 

 It is so easily identified by the black V under the chin that 

 if it occurs there I think we may now be certain of ascertain- 

 ing the fact.

This is the American representative of our common teal. 

 Sir J. Richardson remarks that the only difference he could find 

 between the common teal and its American representative 

 was, that the English bird has a white longitudinal band on 

 the scapulars which the other wants. The American bird has 

 usually a transverse broad white bar not possessed by the 

 English. He makes the two species only varieties, but other 

 authors have followed Pennant, and rightly (as it appears to 

 me) kept them distinct. The female specimen sent me, how- 

 ver, wants the transverse white bar, and Sir John refers to 

 a specimen (he does not say whether male or female) in the 

 Hudson's Bay Company's Museum which wants it.
