The amount of variation in tlii« t^iiecies, shown by the material at haml, 

 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 jirobably 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 

 AtchafaLiya Kiver and its connecting lakes and bayous. Length 4 to 6 

 inches, {atchafalaya', from the type locality.) 



Siijnalosa atchafalaym, Eveemann & Kendall, Bull. IT. S. Fish Comni. 1897 (Feb. 9, 

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

Page 425. The statement that Pomolohiis mediocris does not ascend 

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

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

 They usually run somewhat earlier than the shad.

 projecting. ALABAM.S:, 693(a).

 55^ — 16 in a crosswise series; scutes 21 -f- 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- 

 iecting 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 ec^ual to snout and eye; base of anal somewhat greater
