FISHES FEOM EASTERN CANADA. 

 BY HENRY W. FOWLER. 



Within the past few years the Academy has received several 

 collections from different localities in the eastern and maritime 

 provinces of the Dominion. They have been submitted to me for 

 study, and as several interesting or new records were found among 

 them, this paper is offered as a slight contribution to science. 

 Acknowledgment is here expressed to those who made the collec- 

 tions, and also for such field notes as are appended. 



Lake Cassette. 



This is one of the Rimouski series of lakes in Rimouski County, 

 Province of Quebec. Another connected lake is Long Lake, in the 

 same region. From these waters a number of fresh chars were 

 obtained by Mr. J. E. V. Titus, in September of 1911 and 1912. 

 Salvelinus fontinalis (Mitchlll). 



Two rather well-marked varieties occur, which were thought to 

 be distinct by the fishermen, distinguished locally as the "brook 

 trout" and the "gray back." 



The first of these is of variable color, from very dark to quite 

 light or tan, or even pale brown. Dark examples are quite 

 olivaceous. Red on lower sides ordinarily of deep crimson. In 

 weight they range from one-half to six pounds and four ounces. 

 They are said to spawn in late October, or from late September till 

 late October. Li Touradiff Lake examples occur all quite black on 

 the back, in fact dusky-olive, and with the red of the lower sides 

 swarthy. Possibly this is due to the numerous submerged conifers, 

 besides other timber in the lake, which renders the water and the 

 fish dark. 



The gray-back is distinguished by the alleged variety of its steel- 

 gray color, the blotches and markings appearing very distinct. It 

 does not show red on its lower sides. The old females are known 

 as "bull-dogs," on account of their snub-noses. It reaches a length 

 of eight to eighteen inches, a weight of about three and one-half 

 pounds, and spawns later than the ordinary trout, or in October 

 and November.
