greatest abnndance in tlie swift streams of the South, frequenting 

 especially the rapids or "shoals", and often throwing itself from the 

 water in its endeavors to reach some higher rock-pool. It is too small 

 and the flesh spoils too (juickly to be much valued for food, but great 

 numbers are caught for " lun " by negroes and boys. The largest speci- 

 mens which I have seen were taken in the Chattahoochee, and are about 

 ten inches in length : ordinary individuals are four to six inches long.

This species is well marked by the peculiar form of the under li[>, 

 which is quite small — a narrow, regular crescent following the boundary 

 of the mandible, not full, as in the species previously note«l, ror with 

 the sides folding so as to meet on the middle line, as in the remaining 

 species (excepting ihalassinum). Specimens from Morth Carolina in the 

 National Museum correspond well to Professor Cope's description, except 

 that the back is rather more elevated than one would infer from Pro- 

 fessor Cope's remarks. The dorsal rays are 12 and 13 instead of 11.
