NOTES ON SOME FRESH-WATER FISHES FROM MAINE. 
361 
The Lunkasoos Lake specimens are much smaller than the type — about the size of the cotype, but 
of much darker coloration. The lateral stripe is black; top of head, snout, and opercles black; scales 
outlined with black on back and indistinctly on sides. No spots on dorsal fin of any specimen, but 
on some specimens a dusky shade on front base of dorsal is distinguishable. There seem to be 
about 28 scales before the dorsal, which in some specimens is situated farther back than in the type, 
midway between pupil and base of caudal. Peritoneum black; intestine slightly more than 1.5 body 
without the tail. Pores on 6 to 12 or more scales. Front ray of dorsal not reaching tip of last ray 
when depressed; front of anal just about reaching tip of last rays.

Notropis bifrenatus (Cope). Bridled Minnow. 
This little minnow, collected by Cope in the Schuylkill River and described under the name of 
Uybopsis bifrenatus, has not previously been recorded east or north of Massachusetts. In 1898 it was 
found in abundance by the writer in Sebago and Little Sebago lakes. It inhabits quiet, weedy coves, 
streams, “bogs” or “logans.” It seems to attain a length of not over 2 inches. The form is very 
similar to that of the members of N. heterodon group of minnows. The lateral line is very incomplete, 
usually on 5 or 6 scales. Anterior rays of dorsal and anal, when depressed, extending considerably 
beyond last rays; anal somewhat falcate. 
Color after preservation in formalin and subsequently in alcohol generally as follows: Scales on 
back finely dotted with dark brown, most intense on edges; dark-brown line from top of head, which 
is of a like color, to front of dorsal, less distinct from dorsal to upper base of caudal; a broad, shiny black 
stripe from snout through eye to base of caudal, where it ends in a small jet-black spot; fins all pale. 
In life, while in the water, the back seems of brick-red hue.

Cottus gracilis (Heckel). 
In a small brook tributary to Aroostook River, utilized by the State hatchery at Caribou, Me., 
for fish-cultural purposes, Mr. John A. Story, who is connected with the State Fish and Game Commis- 
sion at that place, collected a good series of Cottus for the writer, who has never observed finer or larger 
specimens elsewhere. It seems to be locally known in the region as “rock cusk,” deriving' its name
