22 to 35 in lateral line to caudal base and 2 more on latter; 6 scales 

 above 1. 1., 4 below, predorsal scales 15 to 18, snout 3^ to 3f in 

 head; eye 3 to 3|; maxillary 2f to 3|; interorbital 3^ to 3f . 

 Body well compressed, rather deep, also head. Muzzle conic, 

 length | its width. Eye large, slightly larger than snout, less than 

 interorbital. Maxillary reaches eye. Upper lip opposite eye center, 

 jaws equal. Interorbital convex. Teeth 1, 4 — 4, 1, hooked, 

 with grinding surfaces. Lateral scales rather narrowly imbricated, 

 predorsal smaller, though without crowded appearance. Scales 

 with 6 to 18 apical marginal striae, circuli coarse. Dorsal origin 

 well behind ventral origin or slightly nearer caudal base than 

 snout tip. Color in alcohol pale grayish, sides of head and lower 

 surface with bright silvery-white tints. Median lateral plumbeous 

 streaks along side of caudal peduncle. Edges of scales on back 

 slightly dusky. Four examples, 55 to 65 mm. long. 



This is the southern deeply-bodied ally of Notropis photogenis 

 and occurs chiefly in the Santee Basin. Though said to be abundant 

 locally we secured only the few examples described above, all 

 with abnormal fins and one with an abortive snout, snub-nosed. 



Hybopsis kentuckiensis (Rafinesque). Young one. 



Gambusia affinis (Baird and Girard). Very common. 



(2). Later in the day we visited Fair Forest Creek, also basin 

 of the Broad River, near Arkwright, Spartanburg County. This 

 is a clear brook where we explored, flowing over a rocky and gravelly 

 bottom. All the rocks were of moderate size. The stream was 

 without any submerged aquatic vegetation, except a little eelgrass 

 in its lower reaches which contained many craw-fishes (Cambarus). 



Notropis lutipinnis (Jordan and Brayton). 



Head 4; depth 3^ to 4; D. in, 7, i; A. in, 6 or 7,i; scales 37 in 

 lateral line to caudal base and 2 more on latter; 7 scales above 

 1. L, 4 or 5 below; predorsal scales usually 17: snout 3^ to 3| in 

 head; eye 3| to 3|; maxillary 2| to 3|; interorbital 2| to 

 2|. Body well compressed deep. Head compressed, short. 

 Muzzle conic, length about f its width. Eye rather large. Mouth 

 moderate, lower jaw slightly included. Maxillary reaches eye. 

 Interorbital convex. Teeth 2, 4 — 4, 2, hooked, with grinding 

 surfaces. Upper surface and sides of head finely tuberculate. 

 Scales all well exposed, slightly crowded before dorsal. Scales 

 with radiating apical striae conspicuous, 11 to 15, circuli coarse. 

 Dorsal origin behind ventral origin, about midway between snout 

 tip and caudal base. Color in alcohol with all fins, at least 

 basally, bright yellow. Males largely with body flushed with 

 pink to reddish. Broad black lateral band very conspicuous, 

 though best defined along caudal peduncle side ; bordering above 

 a gamboge-olive streak. Twenty examples, 47 to 53 mm.
