MUSQUAN RIVER WHITE-FISH. keke 
‘94. CoREGONUS LABRADORICUS Richardson. 
Musquan River White-fish; Labrador White-fish; “ Whiting ” of 
Lake Winnepiseogee. 
Coregonus labradoricus, RICHARDSON, Fauna Boreali-Amer., iii, 1836, 206.—GUNTHER, 
Cat. Fishes Brit. Mus., vi, 176, and of authors generally. 
Coregonus nechantoniensis, PRESCOTT, Amer. Journ. Sci. Arts, xi, 1851, 342. 
Description.—Body rather elongate, compressed, the back not elevated; head rather 
long and slender, compressed ; mouth rather small, the jaws equal, the maxillary reach- 
ing to the front of the pupil; maxillary bone broad, rather short, its supplementary 
piece ovate; tongue with about three series of distinct small teeth; mandible reaching 
middle of eye; eye large, 42 in head; supraorbital bone long and rather narrow ; 
bluish black above, silvery below ; scales with dark punctulations; fins all dusky; dor- 
sal fin high in front, the last rays short; gill rakers slender; head 4% in length; depth 
44; D.11; A. 11; scales 9-80-8. Length about 15 inches. 
Habitat, Great Lake Region to the Adirondacks, White Mountains and northward, 
in cold, clear lakes. 
Diagnosts.—This species may be known from the Common White-fish 
by its slenderer body, larger mouth and evidently stout small teeth, the 
form of the mouth readily separates it from the ‘‘ Lake Herring” and its 
relatives. 
Habits.—Little distinctive is recorded of the habits of this species. It 
is very abundant in Canada and northern New England, but I have 
seen no specimens from Lake Erie, and do not know that it occurs there. 
It is said to rise to the fly in the Canadian Lakes.
