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 Sornateria 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. Eichardson 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.
