larger one is profusely covered with small dark spots. One specimen 

 from Los Amates, Guatemala, is of a verj^ light uniform color. No 

 dark or light bars are present on any of these specimens. Two speci- 

 mens in the Museum collection from South America have quite a differ- 

 ent coloration ; one is a very dark brownish color crossed by narrow 

 yellowish bars, which are less than half as wide as the interspaces ; on 

 the other the yellow bars are much wider and nearly as wide as the 

 interspaces. The darker bars are more or less interrupted by partial 

 light yellow bars. 



This species is reported as ver^'' scarce in the head of the outlet of 

 Lake Amatitlan. It is very tenacious of life and so is prized for the 

 aquarium. It is also regarded as a ver}'' superior food fish.
