ANALYSIS OF THE SPECIES OF MICROPTERUS. 
a. Mouth moderate, the maxillary in adult not extending beyond eye; scales small, 
about 11-74-17 ; young more or less barred or spotted, never with a lateral

rather large, about 7-68-16; last spine of dorsal short, so that the fin is almost 
divided in two ; young with a blackish lateral band Salmoides, 26.

Habitat: Lake Champlain, Manitoba, and southward to Kansas, on 
both sides of the mountains from James River southward, chiefly in 
clear lakes and running streams. 
Etymology : To M. Dolomieu, a naturalist, of Paris, at the end of 
the last century. As the synonymy of the two species of Micropterus 
is now well established, I have nothing new to offer concerning them. 
For a complete account of both species of Micropterus see HeushalFs 
excellent “Book of the Black Bass,”
