NOTES ON SOME FRESH-WATER FISHES FROM MAINE. 
367 
Type, No. 50828, U. S. N. M., a male 222 mm. (nearly 9 inches) long, from thoroughfare between 
Mud and Cross lakes, Maine, October 23, 1901. Cotype No. 2746, U. S. F. C. 
Named for Hon. Henry 0. Stanley, one of the commissioners of inland fishes and game of Maine. 
The males of this species are conspicuously marked with the white tubercles, and many, though 
not all, of the females have them to a lesser extent. In this respect they resemble Coregonus vAUiarit- 
soni, but otherwise differ markedly. The tables of proportional measurements do not reveal a great 
many characteristics to distinguish this fish from its closely- related cogener, C. labradoricus, of the 
same waters. But to the eye, specimens compared may be readily distinguished by the sharper, less 
truncated snout, shorter appearance of the head, having more the general appearance of C. quadrilater- 
alis, yet differing from this in conspicuous details, such as body less slender, shape of head, less curved 
profile, less compressed snout, and larger mouth, etc. 
Then again, it is of much smaller adult size than C. labradoricus, which in the same waters 
attains a weight of 5 pounds. In the breeding season it is more conspicuously and characteristically 
tuberculated, and the height of the spawning season on the same grounds is one month earlier. On 
the average there are more gillrakers, which are considerably longer than in the other species. 
A female 230 mm. (a little over 9 inches) in length contained 3,447 eggs. 
This fish abounds in the chain of Eagle Lakes, and is doubtless a conspicuous item in the menu 
of salmon, togue, and trout. Reports of small white-fish from other parts of the State indicate that 
this species may be common in other waters. It is never, or very seldom, seen, except in breeding 
season, but very likely could be caught with line-meshed gill nets made of fine twine if set in deep 
water. It is an excellent pan fish.
