Purplish gray; lower parts whitish. Pectorals, ventrals and anal vermilion. Eye pale 

 golden. Head, especially behind the eyes, iridescent gold and puqile tints. Caudal was 

 chiefly vermilion in life. 



The fish is a male with ripe milt. There are numerous small tubercles on the scales of the 

 sides above and below the lateral line. 



37. Coregonus clupeiformis (Mitchill). Whitefish. — A single young individ- 

 ual, caught in a gill-net at Wilson, Niagara County, N. Y., in Lake Ontario, was 

 forwarded by Mr. James .\nnin, Jr., for identification. 



38. Coregonus labradoricus {Richardson). Labrador Whitefish. — This spe- 

 cies is frequently confused with the common whitefish of the Great Lakes {C. clitpci- 

 formis), especially itt waters into which fry of the latter fish have been introduced. It 

 is also mistaken sometimes for the black-fin whitefish {Argyrosorniis iiigripinnis) ; but 

 a glance at the jaws should correct that error speedily. From the common whitefish 

 it may readily be distinguished by the lingual teeth (unfortunately not always present) 

 and its compressed back, as well as its small size. 



A male and a female were received through Mr. James Annin, Jr., from Upper 

 Saranac Lake on November 16, 1895. Both fish were nearly spent. They were sup- 

 posed to be the common whitefish. A male from Chazy Lake arrived through the 

 same source on November 22, 1895. It was doubtfully called •' black-fin whitefish." 

 At that time the fish had left the spawning beds and were in deep water. On June i 7, 

 1896, a female 1954 inches long was shipped by Mr. Annin from Canandaigua Lake.
