282 SEVENTH KKI'OKT OF THE FOREST, FISH AND GAME COMMISSION. 



Dr. Evermann collected two specimens in Black Creek, tributary of Oswego River, 

 at Scriba Corners, N. Y., July 17, 1894. Dr. Meek found it very common about 

 Cayuga. and Montezuma, N. Y., but did not observe it near Ithaca. In the market 

 of New York, according to DeKay, the Chub Sucker makes its appearance in Octo- 

 ber, November and December. Specimens were seined in Bronx River in August, 

 1897. 



A young example sent from near Princeton, N. J., by Prof. Ulric Dahlgren in 

 September, 1897, showed the following voluntary change of color: When it arrived, 

 it had the broad, longitudinal median band well developed and the vertical bands 

 obsolete; but soon after it was placed in a tank it obscured the longitudinal band 

 entirely and developed the vertical bands. 



The food of the Chub Sucker consists chiefly of minute crustaceans, insect larvae 

 and aquatic plants. 





STRIPED SUCKER. 



25. Striped Sucker (Minytrema mclanops Rafinesque). 



Minytrema melanops JORDAN, Bull. 12, U. S. Nat. Mus. 138, 1878; BEAN, Fishes Penna., 

 28, pi. 21, fig. 32, 1893. 



The Striped Sucker, also called Soft Sucker, Sand Sucker, and Black-nosed 

 Sucker, is found in the Great Lakes and south to South Carolina and Texas. In 

 Pennsylvania it is limited to Lake Erie and the Ohio Valley. In New York it is to 

 be expected in Lake Ontario and its tributaries, and should also occur in Chautau- 

 qua Lake. 



The Striped Sucker grows to a length of 18 inches. Old males have the head 

 tuberculate in the breeding season in the spring. The species is very readily 

 distinguished by the dark stripes along the sides produced by spots at the base of 

 each scale. In the young of this sucker there is no lateral line but in adults it is 

 almost entire. This sucker prefers clear, sluggish waters and grassy ponds. It
