FISHES OF NEW YORK 



305 



Examples of unspotted mascalonge were received at the New 

 Tork aquarium from Chautauqua lake, N. Y. which belongs to 

 the Ohio river drainage system. It appears that the typical 

 spotted form also inhabits the Ohio basin, but occurs rarely. Mr 

 Annin sent one individual Dec. 4, 1895, and two on May 4, 1896; 

 from these three were obtained the following notes and measure- 

 ments in inches.

In all the specimens the maxilla extends to below the front 

 «dge of the pupil. The gill rakers are mere clumps of spiny 

 tubercles. In the two males the diameter of the eye is con- 

 tained from four and one third to five times in the length of the 

 snout, an^ from 10 to 11 times in the length of the head. 



In the individual of Dec. 4, 1895, the lateral line tubes are 

 distributee! over various parts of the sides without much regu- 

 larity except in the median line. There are no black spots. 

 About 20 entire, blotchlike, irregular cross bands and several 

 jparts of bands and blotches intervening. The lower third of
