 almost terminal; snout blunt; top of head and snout flat; scales 

 rather large. Males and females of about equal size; first three anal 

 rays make the tube of the slightly prolonged anal of males. One 

 has the entire anal rolled up in such a way that no rays are visible, and 

 has a three-fingered tip. The alimentary canal is shorter than the 

 length of the body and does not appear to contain any mud.

 easily detached; diameter of eye less than length of snout, almost 2

 thirty, and those of the posterior part of the median lateral row with 

 peculiar dark central pits or holes. Origin of dorsal nearer the tip 

 of caudal rays than the snout, and slightly in advance of first anal 

 rays (e.xcept in two of the younger specimens). Almost cylindrical

 body is compressed. All fins colorless; rather broad darkish lateral 

 band more or less complete in adults, but broken into blotches' in 

 young; dorsal side dusky, and a dusky band below distinct lateral 

 band; ventral surface yellowish white. 



This specimen was caught under stones in rapid water, where it 

 acts like Characidium.
