FISHES OF NEW YORK 497 



James Annin jr of Caledonia sent two individuals Ap. 23, 1896, 

 for identification. They furnished the following notes and 

 measurements in inches.

The pyloric caeca are long and loaded with fat. The male is 

 brassy; the female gray and whitish. 



In November of 1896 and 1897 Mr Annin shipped adult individ- 

 uals from Canandaigua lake by express without an attendant, 

 and there was scarcely any loss of fish in transportation, though 

 the journey lasts 12 hours. 



The blue pike of Lake Erie, or white salmon of the Ohio river, 

 was formerly distinguished by name from the common pike 

 perch, but is now considered unworthy of a separate name. This 

 is a very small variety seldom exceeding 15 inches in length and 

 a weight of 2 pounds. The dorsal has 14 spines and 20 rays. 

 The spines are rather lower than in the pike perch, the colora- 

 tion similar, but the adult is bluish or greenish and has no brassy 

 mottling. The fins are darker, and there is a trace of a band 

 along the dorsal, besides the black blotch on the hind portion. 



Jordan & Evermann say of this variety: "The name sal- 

 mo n e u m has been applied to the so called ' blue pike ' origin- 

 ally described from the Ohio river, but more common in the Great 

 lakes, particularly Ontario and Erie. It is smaller and deeper 

 in body than the ordinary v i t r e u m and different in color, but 

 it is not likely that any permanent distinctions exist, this 

 species, as usual among fresh-water fishes, varying largely with 

 the environment and with age."
