since 1893, when it was first noticed there. Nash (1908) reports it as 

 occasionally taken in Lake Superior. 



9. Leucichthys cyanoptera Jordan and Evermann. — Found in deep 

 water of Lake Superior (Jordan and Evermann 1911). 



10. Leucichthys zenithicus (Jordan and Evermann) .—This form ac- 

 cording to Jordan and Evermann (1911) and H. ~Sl. Smith (1894), 

 occurs in deep waters of Lake Superior. 



11. Leucichthys manitoulinus Jordan and Evermann. Manitoulin 

 Tullibee. — North channel of Lake Huron and perhaps in Lake Superior 

 according to Jordan and Evermann (1911). 



12. Cristivomer namaycush (Walbaum). Lake Trout. — No lake 

 trout were found by the writer, but there is abundant evidence that they 

 occur at least in the deep water near Vermilion. Mr. N. A. Wood got 

 one w^eighing fifteen pounds about a mile out from Vermilion in the 

 summer of 1914. John Clarke informed the writer that they frequent 

 the shoal at times, and other reliable testimony as to their occurrence 

 there was obtained. A number of plantings of the species have been 

 made at Whitefish Point and Grand Marais. 



The lake trout is a well-known predator. The one taken in 1914 by 

 Mr. Wood had five sculpins, each about three inches long in its stomach. 

 Nash (1913) states that they eat herrings, young whitefish, and other 

 soft-finned fish. Mr. John Clarke saj^s that they spawai in fall in five or 

 six feet of water where the bottom is gravelly in Lake Superior. Nash 

 (1908) states that the spawTiing season in Lake Superior commences 

 early in October. 



13. Cristivomer namaycush siscowet (Agassiz). Siscowet. — This sub- 

 species is said to live in Lake Superior, in water from three hundred to 

 nearly five hundred feet deep. Jordan and Evermaim (1911) state 

 that, "It is never seen in shallow water." It is doubtful if it should 

 be included in this list. 



14. Salmo gairdneri Richardson. Steelhead Trout.- — These trout 

 have been planted in streams tributary to Lake Superior and are said 

 to frequent the open lake. Nash (1908) states that they have been 

 introduced in Lake Superior with marked success. 



15. Hiodon tergisus Le Sueur. Toothed Herring.^ — Probably occurs 

 in Lake Superior. Nash (1908) states that it ranges to Lake Superior. 



16. Alosa sapidissima (Wilson) . The Shad. — Mr. Robert Carlson re- 

 ports taking one at Whitefish Point. Nash (1908) says ''it was formerly 

 abundant in the lower Ottawa but has abandoned that river and its 

 occurrence within our boundaries is now only accidental. 



17. Pimephales notatus (Rafinesque). Blunt-nosed Minnow. — Re- 

 corded from Sault Ste. Marie by Meek and Clarke ( 1 902). j^^^ Found in
