1^ in head; ventral i}{ in head; base of anal i%" in head; caudal 

 peduncle rather slender, its least depth 2^ in head; scales rather 

 deeper than long; lateral line decurved, complete. 



Color rather light brownish, with a lateral plumbeous band,

This species resembles Nototropis lutrensis, differing, however, from 

 it in having a better developed lateral band, a faint caudal spot, 

 and a larger eye. Spawning time the latter part of May. (Forlon, — 

 name of the river from which the type was taken.)
