THE BROOK TROUTS OR CHARS. 477 
extensively salted at Kadiak in the sea-run condition under the name of 
Salmon Trout. Examples of twenty-four inches in length are known. 
The Greenland Trout, Salvelinus stagnalis, a native of Arctic 
America, is believed by Bean to be, with little doubt, the ‘‘Sea Trout’’ 
of Labrador, and of Canada. It rivals the Atlantic Salmon in size, and 
has no near connection with the ‘‘ Sea Trout’’ of Europe. It is interest- 
ing to know that the anglers have probably been in the right and the 
ichthyologists wrong in regard to this interesting species, concerning 
which as yet we know very little. Hallock and others of our anglers 
have described its qualities as an angling fish very fully. S. stagnalis 
occurs in the lakes of Greenland. The National Museum has specimens 
from Disko, taken by Ensign Dresel, and from Labrador, obtained by 
Turner. 
THE OQUASSA OR BLUE BACK TROUT. 
Salvelinus oquassa inhabits the lakes in Western Maine; thence intro- 
duced into New York and New Hampshire. This is, says Bean, a small 
species, not known to exceed ten inches in length from existing collections. 
It is probably a land-locked form of S. stagnalis, and specimens of much 
larger size may be expected. Its distribution, also, will be found to be 
more extensive. 
Closely related to the Oquassa is the Saibling, introduced into Massa- 
chusetts, New York, New Hampshire and Wisconsin, which, according 
to Bean, so closely resembles some of our native Chars as to make its 
recognition difficult A hybrid between the Saibling and our common 
Brook Trout has further increased the trouble of identification. 
This form, whether it be regarded as a single species or several related 
species, is distributed over all of Northwestern Europe, and possibly also 
over a portion of Asia, although, since the Asiatic representatives of the
