THE BROOK TROUTS OR CHARS. 479 
duction may be a success, and this hope was realized, for they proved 
satisfactorily hardy, and on December 3, 1883, about 600 eggs were taken 
by Commissioner Hodge. 
There are three other little known fishes of this group, now under study 
by Dr. Bean. 
Salvelinus Rossti, which occurs in the Arctic Ocean about Boothia Fe- 
lix, has recently been detected by him in the province of Quebec, Canada. 
It is a very large species, reaching more than two feet in length, accord- 
ing to Richardson. The best distinguishing character is the shape and 
striation of the opercular bones. 
Another is Salvelinus arcturus, which has been taken in Victoria Lake 
and Flocking Beach, Arctic America, and is the northernmost salmonoid 
known. This he remarked may be one of the forms of stagnalis, but 
specimens with red spots are still unknown. Last of all is the Sunapee 
Trout, S. Agasszi/, a form little understood, occurring in Sunapee Lake, 
N. H., which is being investigated by Prof. Quackenbos, Col. Hodges and 
Dr. Bean.
