206 FISHES OF WESTERN SOUTH AMERICA 
Where in maculata the granular border on the lower surface of the snout is of 
nearly uniform width, in cashibo it is twice as wide in front as it is along the sides. 
In maculata the supraoccipital and the plates behind it are smooth; in cashibo there 
is a double ridge on the supraoccipital, and the plates behind it are bicarinate. In 
many characters the specimen is not clearly differentiated from L. maculata. 
For the indigenous tribe of the region, the Cashibos, who have given their 
name also to the lake, Cashiboya, the type locality, an oxbow lake formed in an old 
channel of the Ucayali.
