The amount of variation in this species, shown by the material at hand, 

 is exhibited in the following table : 



This species appears to be rather common in the larger lowland streams 

 and bayous of Louisiana and Mississippi. It probably does not reach a 

 large size, adult examples being less than 6 inches long. It is not used 

 as food, but is of considerable value as bait in the catfish fishery of the 

 Atchafalaya River and its connecting lakes and bayous. Length 4 to 6 

 inches, (atchafalayw, from the type locality.) 



Signalosa atchafalayce, EVERMANN & KENDALL, Bull. U. S. Fish Comm. 1897 (Feh. 9, 

 1898), 127, pi. 7, fig. 4, Atchafalaya River, Melville, Louisiana. (Type, No. 48790.

Page 425. The statement that Pomolobus mediocris does not ascend 

 rivers to spawn is not correct. This species is known to ascend the St. 

 Johns River, Florida, at least as far as Lake Monroe, during the winter. 

 They usually run somewhat earlier than the shad.

 55, 16 in a crosswise series; scutes 21 + 15 ; vertebra 54; gill rakers 56 

 to 68. Body deep; back gently and evenly arched from tip of snout 

 to origin of dorsal fin, thence descending in a regular curve to base of 

 caudal fin ; ventral outline nearly straight from tip of mandible to ven- 

 trals, and also from there to base of caudal. Head small, snout pointed ; 

 upper lip with a small notch, into, which fits the tip of the slightly pro- 

 jecting lower jaw; maxillary narrow; cheek much deeper than long; 

 teeth on tongue and maxillary scarcely perceptible. Origin of dorsal 

 nearer snout than base of caudal, the fin low, the longest ray shorter than 

 the base, or about equal to snout and eye; base of anal somewhat greater
