136 FIELD COLUMBIAN MUSEUM ZOOLOGY, VOL. III. 



Salvelinus fontinalis (MitchiH). Brook Trout. 



We collected a few specimens of this species in Trout Creek 

 and at Sault Ste. Marie. It is widely distributed over Ontario, 

 but is usually confined to the streams. Specimens are occasion- 

 ally taken in Muskoka Lake. 



Salmo irideus Gibbons. Rainbow Trout. 



This species is introduced into streams of Michigan. A large 

 number of eggs are hatched each year at Sault Ste. Marie. 



Lucius lucius (Linnseus). Common Pike; Pickerel. 



This species is known as pike in Ontario. The pickerel of 

 that region is Stizostedion vitreum. It is not found in Muskoka 

 Lake nor in Gull Lake. It is reported as common down the 

 river below the second falls about 4 miles below Bala. The 

 muskallunge conies up the river within 8 miles of Bala. Rock 

 bass and big-mouthed black bass are reported to be in the river 

 from 6 to 8 miles below Bala. 



At Chapleau this species was very abundant. In trolling a 

 distance of about 3 miles around a small lake we caught 36 fish 

 about 15 to 19 inches in length. There are no black bass or wall- 

 eyed pike in the lake at Chapleau, and so this species, together 

 with the whitefish found here, is depended upon to furnish sport 

 for the angler and fresh fish for the inhabitants. 



We saw none of this species except at Chapleau. 



UMBRID^. 



Umbra lirni (Kirtland). Mud Minnow. 



One specimen taken at Gravenhurst. Common in bayous of 

 a small creek near Bala. 



PCECILIID.E. 



Fundulus diaphanus rnenona (Jordan & Copeland). 



Cross bars 14 to 17; scales about 48; dorsal fin with a narrow 

 black bar on its lower half; a black spot at base, and another at 

 tip of last rays; common. Orillia.
