were a few young whitefish and other species. These young 

 herrings were, in all probabiHty, the same species as the adults 

 taken from the deeper shoal, but since there are at least four other 

 Leucichthys in Lake Superior (L. swpernas, L. cyanopterus, L. zenithicus, 

 and L. tullibee), whose young are apparently unkno^vn in this body 

 of water, it is possible that they also have young representatives on 

 the shoal. 



The coloration of one of the large herrings from Station 2, just as it 

 was taken from the water, was as follows: upper parts, yellowish olive, 

 except for a porcelain green streak just back of the dorsal fin; lower 

 parts white, with light pinkish lilac reflections on the sides; dorsal and 

 caudal fins olive; lower fins white. The very small herrings caught 

 close to shore were similar in color to the large ones, but they were 

 paler and more silvery on the sides. 



Many lake herrings are caught at the Whitefish Point fishery. Mr. 

 Carlson reports sixty tons taken there in 1914. They Constituted the 

 chief food fish for residents of Vermilion during the time the writer was 

 in the region, and they are of much importance to these people. Many 

 of them were discarded as unfit for food on account of parasitic worms 

 in them. These were of two types: nematodes in coiled masses in 

 the coelome and cestodes embedded in the flesh of the back. 



Four small ones were examined as to their food, which was found to 

 consist entirely of entomostracans, chiefly Cyclops viridis hrevispinosus. 



Forbes (1888) and Juday (1907) give notes on the food of Lake 

 Herrings. G. B. Goode (1884) considers them great destroyers of 

 whitefish eggs. 



4. Leucichthys tullibee (Richardson)? Tullibee. — A tullibee was taken 

 by a fisherman at Station 2, in a gill net (Plate XXVIII). In depth of 

 body, size of eye, and number of branchiostegals, it is more like L. 

 manitoulinis than L. tullibee, but it is most like the latter in length of 

 head, maxillary, and anal fin and in the number of gill-rakers and 

 scales before the dorsal fin. It, therefore, seems best to assign it to 

 the species tullibee, but not with positiveness, because these char- 

 acters are apparently variable (see table page 33, Jordan and Ever- 

 mann 1911), because either species may be found in Lake Superior, 

 and because the writer is able to examine but one specimen of tullibee 

 and is unable at present to compare this with type specimens. 



The following descriptive notes were made on this fish: Length, 

 10.6 inches; length to base of caudal fin, 8.5 inches; depth in length (to 

 base of caudal) 3.3; adipose fin in eye, 1.3; eye in head 4.4; caudal 

 peduncle, 2.5 in head; head in length, 4.3; dorsal fin with 12 developed 

 rays; anal with 12 rays; scales in lateral line, 74; branchiostegals, 8;
