TULLIBEE. 885 
Description —Body stout, fusiform, compressed; head stout; mouth large, the lower 
jaw projecting; eye rather large, longer than snout, about four in head; teeth very 
- minute asin C. artedi, but appreciable on premaxillaries and tongue; gill-rakers very 
numerous, long and slender; lower fins long; color dark bluish above; sides silvery, 
with dark punctulations; fins all blue-black ; head 44; depth 32; D. 10; A. 12; scales 
7-86-6, Length, 15 to 18 inches ; average Sin 14 pounds. 
Habitat, deep waters of Lake Michigan. Not yet noticed in Lake Erie. Especially 
abundant in Grand Traverse Bay. 
Diagnosis.—From the Lake Herring, the larger size, stouter form, and 
especially the deep blue-black color of the lower fins readily distinguish 
it. | 
Habits.—This species is as yet known only from the deep waters of 
Lake Michigan where it is found in company with Coregonus hoyi. It is 
occasionally seen in the markets of Chicago, sometimes in considerable 
numbers. Its qualities as a food fish are probably similar to those of the 
W hite-fish. :

' Description Body short, deep, compressed, shad-like, the dorsal and ventral curves 
similar; caudal peduncle short and deep; head conic, compressed, much as in C. nig- 
ripinnis ; mouth large, the maxillary as long as the eye, extending past the front of the 
pupil, its supplemental bone narrowly ovate, with prolonged points ; jaws equal when 
closed ; eye large, as long a3 snout, four and a half in head; preorbital narrow; supra- 
orbital elongate, rectangular; scales anteriorly considerably enlarged, their diameter 
half larger than the diameter of those on the caudal peduncle; color bluish above; sides 
white, punctate with fine dots; each scale with a silvery area, these forming a series of 
distinct longitudinal stripes; head 4; depth 2; D. 11; A. 11; scales 8-74-7. Length, 
18 inches. 
Habitat, Great Lakes and northward. 
Diagnosis —The Tullibee has the deep, compressed form of the Shad, 
with the projecting lower jaw of the Lake Herring. These particulars 
distinguish it at once from the other White-fishes. 
_ Habits.—Scarcely anything is known of the habits of the Tullibee. It 
is certainly not abundant in any of the Great Lakes, although probably 
occuring in all of them. I once received a photograph of a Tullibee, from 
Dr. H. Sterling, of Cleveland, Ohio. The specimen had been taken in 
Lake Erie and Dr. Sterling informed me that it was known to the fisher- 
men as the “ Mongrel White-fish,” they thinking it to be a hybrid 
between the White-fish and the Lake Herring.
