Etymology, telestes, perfect. 
This genus as here understood includes a very wide range of forms, agreeing in having

grinding surface; dorsal more or less posterior, usually behind the ventrals; scales 
moderate or sinall, the lateral line complete; caudal fin without a great number of re- 
current rudimentary rays ‘The species are numerous in Enrope, Asia, and Western 
Amorica. Thesingle species thus far noticed ia Ohio, baloags to the subgenus Clinos-

small; fins short and high, the dorsal somewhat behind ventrals; lateral line decurved ; 
color dark bluish, the scales mottled with paler; sides with a broad black band; belly 
more or less silvery; the front half of the lateral band bright crimson in spring males, 
the belly and lower fins more or less reddened, a dark vertebral band; head 4; depth 
5; D.8; A. 9; scales 10-70-55 teeth 2, 4-5, 2. Length 4 inches. 
Habitat, Great Lake Region and Ohio Valley. 
Diagnosis.—The great size of the mouth and the small size of the scales 
distinguish this species from all other minnows found in Ohio. 
Habits.—This is one of the most brilliant of our minnows. It fre- 
quents clear, cold streams, and is therefore more abundant in the tribu- 
taries of the lake than in those of the Ohio River. It is unsurpassed as 
an aquarium fish.
