Head 4.34; depth 4.2; eye 4; snout 4; D. 8; A. 10; scales 7-39-4, about 15 

 before dorsal. General form much like that of Hybognaihus; body only 

 moderately compressed, dorsal and ventral outlines slightly arched; head 

 lather small, pointed; mouth small, a little oblique, the maxillary scarcely 

 reaching anterior border of orbit, lower jaw slightly included; snout equal 

 to eye; eye in axis of body. Fins all rather small; origin of dorsal slightly 

 behind vertical at insertion of ventrals; free edge of dorsal fin somewhat 

 concave, the anterior rays about equal to length of head; pectoral short, 

 slightly falcate, the longest rays about 1.4 in head ; ventrals shorter than 

 pectoral, barely reaching vent; anal similar to dorsal, the rays shorter; 

 caudal widely forked, the middle rays 2.5 in the outer, the lobes as long as 

 head, the lower lobe slightly longer than the upper; scales moderately 

 imbricated, the exposed portions not deeper than long; lateral line com- 

 plete, somewhat decurved. Teeth 2, 4-4, 2 or 1, rather weak, hooked, and 

 with small grinding surface. Intestine short; peritoneum silvery. 



General color light straw ; middle of side with a broad, well-defined sil- 

 very band from upjter end of gill-opening to middle of base of caudal fin, the 

 anterior half lying wholly above the lateral line, the posterior jiortion lying 

 partly below it; this silvery band bounded above l)y a narrow dark border; 

 cheeks and opercles silvery; a darkish band along median line of back; fins 

 all plain straw-color or pale lemon. 



Fourteen examples of this species, 2 to 3 inches in length, were obtained 

 from the Atchafalaya River at Melville, La., by Mr. Fred. M. Chamberlain, 

 for whom the species is named. 



25. Notropis louisianae Evermann. 



Type, No. 48902, U. S. Nat. Mus. ; cotype. No. 708, U. S. F. C. Type locality, 

 Atchafalaya River, Melville, La. Collector, Fred. M. Chamberlain. 



Head 4.5; depth 5.6; eye 3; snout 3; D. 8; A. 11; scales 7-37-3, 19 or 20 

 before the dorsal. Teeth 1,4-4, 2, little hooked; peritoneum silvery, with 

 numerous minute round black specks. Body long and slender, back not 

 arched; head short but pointed; mouth rather large, oblique, maxillary 

 scarcely reaching orbit ; lower jaw somewhat included ; eye large, equal to or 

 greater than snout. Fins rather small ; origin of dorsal far behind insertion 

 of ventrals, its longest rays 1.4 in head; pectorals short, their length equal 

 to height of anal; ventrals very short, 2 in head, caudal deeply forked; 

 scales firm, moderately imbricated; lateral line complete, gently decurved. 

 Color pale; side with a faint plumbeous band; back and upper part of sides 

 with numerous dark specks chiefiy on the margins of the scales, thus forming 

 cross-hatchings; a narrow dark vertebral band on caudal peduncle. Length 

 2.5 inches. Known only from the Atchafalaya River, Louisiana. 



This species resembles Notropis dilectiis, but has a much smaller mouth, 

 blunter snout, and is less silvery along the side. 



26. Notropis venustus (Girard). Two specimens from Michelli. 



27. Notropis iiotemigonoides Evermann. Two specimens from Michelli and 11 



from ponds near Beaumont. 



28. Anguilla chrysypa Rafinesque. Baldwin Lodge and Atchafalaya River, though 



not abundant. Considered excellent catfish bait by the Atchafiilaya River 

 fishermen. 



29. Hiodon alosoides (Rafinesque). Toothed Herring; LaQuesche; "Slicker." One 



specimen from Melville; seen at other places along the Atchafalaya River, 

 where it is used as bait in the catfisli fishery. The specimen from Melville 

 agrees exactly with more northern examples. 



30. Dorosoma cepedianum exile .Jordan iS: Gilbert. Hickory Shad; "Shad." 



Rather common in the Atchafalaya River, where it is of considerable impor- 

 tance as bait. Four specimens from Melville. Doubtless occurs in most 

 waters of this region.
