Represented southward by 



3!)4a. ABRAMIS CRTSOLEUCAS BOSCI (Cuvier & Valenciennes). 



Head4; depth 3; eye 3. D.8; A. 15 to 17; scales 8-43 to 50-2; teeth 

 5-5. Scales larger, the anal fin more elongate, and the male with brighter 

 colors. Body moderately elevated, very strongly compressed ; head rather 

 broad and flat between the eyes; mouth small, quite oblique, the maxil- 

 lary barely reaching the eye; eye very large and prominent, anterior. 

 Dorsal fin short and very high, almost falcate, well back; anal fin high 

 and long. Scales rather large, the lateral line running very low. Color 

 pale olive, with silvery luster; lower fins red in the males in spring. 

 Length 12 inches. Rivers of the South Atlantic States ; abundant from 

 the James to the Altamaha and St. Johns ; intergrading with the typical 

 form. (Named for M. Bosc, a French naturalist and collector, consul at 

 Charleston toward the end of the eighteenth century.)

This genus has the general character and appearance of CUola and 

 PimepJiales, the dentition and the structure of the fins being the same; 

 the teeth, however, are rather more strongly hooked and with deeper 

 grinding surface. It differs in the structure of the jaws, which are pro- 

 vided each with a hard cutting plate, in appearance similar to that of 

 Dioclon, the sharp, bony edge being surrounded by the usual lip. First 

 ray of dorsal separated by membrane, and spine-like, as in CUola and 

 Pimephales. Alimentary canal short. Peritoneum white. Psendo 

 branchiae present. Lateral line complete. Anal fin small. Spring males 

 with tubercles and dark pigment as in Fimephales. We place this genus 

 and CUola in the neighborhood otNotropi*, on account of the shortness of 

 the intestines, but it is likely that their real relations are with Pime- 

 phales, and that the reduction in the length of the alimentary canal is a
