SHIRAS EXPEDITIONS TO WHITEFISH POINT. 153 



On tlie preparation of this list the writer made manj- inquiries of 

 meml)ers of the Life Saving crew at VermiUon and of others famiUar 

 with the aquatic hfe there, who were willing and capable of giving 

 reliable information; and he has examined the literature pertaining to 

 Lake Superior fish, and has corresponded with ichthyologists who 

 might furnish facts concerning the aquatic l^iota of the region. Chiefl}^ 

 from these sources the data given in the following hypothetical list has 

 been obtained. 



1. Acipenser ruhicundus Le Sueur. Lake Sturgeon.— Sturgeons are 

 said to visit the shallow water of Lake Superior near Vermilion, and 

 Mr. John Clarke informed the writer that they used to run up the 

 Tahquamenon River which enters Whitefish Bay. Records of sturgeons 

 in Lake Superior are given by Smith and Snell (1885), who say that they 

 are captured there but seldom marketed. Cox (1897) states that they 

 are often taken in Lake Superior. Townsend (1902) reports 711 

 pounds taken from Lake Superior in 1899 with pound and trap nets, 

 and asserts that they are not as common in Lake Superior as in the 

 other lakes. 



2. Amia calva Linnaeus. Dogfish. — Air. Robert Carlson reports 

 that the dogfish or bowfin is caught at Whitefish Point. 



3. Leucichthys harengus ardurus Jordan and Evermann. — -This 

 subspecies was recently described by Jordan and Evermann (1911). 

 The type specimen is from Knife River, Duluth, Minnesota. It is 

 possible that all L. harengus of Lake Superior belong to this subspecies. 



4. Leucichthys eriensis (Jordan and Evermann). — Recorded from 

 Port Arthur, Lake Superior, by Fowler (1911). 



5. Leucichthys supernas Jordan and Evermann. Cisco of Lake 

 Superior. — The species was described by Jordan and Evermann (1911). 

 It is said to be a deep water form, living in water 300 feet or over in 

 depth. Absence of information concerning the habits and character- 

 istics of the young of this and other Leucichthys of Lake Superior, 

 makes it impossible to determine whether or not this species is repre- 

 sented in the hosts of little herring that school in the shallow water of 

 Lake Superior near Vermilion. 



6. Leucichthys prognathus (H. M. Smith.) Cisco of Lake Ontario. — • 

 Xash (1908) reports this fish from the Great Lakes except Lake Erie, 

 and it is recorded from Devil's Isle, Lake Superior, by the Bureau of 

 Fisheries at Washington (Michael 1904). 



7. Leucichthys johannae (Wagner). — Found in Lake Superior, ac- 

 cording to Wagner (1910). 



8. Leucichthys nigripinnis (Gill). Blackfin of Lake ^Michigan. 

 The blackfin is said to be common in Whitefish Bay. Townsend 

 (1902) states that 36,818 pounds have been taken in Whiti^fisli Bay
