liotel, 7 miles northeast of Oswego, and Marsh creek. In the 

 St Lawrence river basin he and Barton A. Bean obtained the 

 joung in Racket river, Norfolk N. Y., July 18 and in the St 

 Lawrence river, 3 miles below Ogdensburg, July 17. In the Lake 

 Ohamplain basin these two collectors secured young and half 

 ^rown specimens in the Saranac river, at Plattsburg July 28, 

 1894. 



The w^riter received specimens from Canandaigua lake in 

 November of 1896 and 1897, and seined the young in Bronx river 

 in August 1897. The small mountain form was secured from 

 Saranac lake in November 1897. It is conspicuous for its small 

 size and its red color. The Canandaigua lake suckers, received 

 in November 1896, throve in captivity till July 1897, when the 

 -warm water killed them. 



Color brownish, olivaceous above, silvery below; the young 

 are much blotched and marked on sides and back. It is occas- 

 ionally caught on the hook. Young ones, in captivity, though 

 they always grub about, and though they take food offered 

 them, do not thrive and gradually starve. They remain wild 

 and take alarm easily and often leap out of their tank. This 

 species enters slightly brackish water. Eugene Sndth?-

The stone roller has a peculiar physiognomy. The head is 

 flattened on top, the interorbital space is concave and the fron- 

 tal b©ne short, broad and thick. The body is subterete, its 

 depth being contained four and on-e third times in the length 

 without caudal or equal to length of head. The eye is rather 

 small, being contained three times in length of snout; mouth 

 large, lips well developed and strongly papillose; fins all large;
