FISHES OF THE SANTEE BASIN. 25 



rather shorter than the long muzzle, placed nearly midway in head, 

 about 3 in head. 



Mouth rather large, inferior, the lips much thickened, Sucker-like ; 

 upper jaw extremely protractile ; the lower with a conspicuous internal 

 fringe of papillae. 



Barbels extremely long, probably longer than in any other of our 

 Cyprinoids ; their length to | the diameter of the eye. 



Scales moderate, pretty closely imbricated, 5-40-3 ; 15 or 16 in front 

 of dorsal. Lateral line continuous, slightly deflected forward. 



Fins rather small, high, and short. Dorsal 1, 8, originating slightly 

 behind the base of the ventrals, as in C. labrosus and C. monaclius. Anal 

 1, 7. Caudal deeply forked, its peduncle long and slender. 



Coloration, in spirits, quite pale ; a small, round, black spot at base * 

 of caudal : dorsal scales dark-edged : some dark points along caudal 

 peduncle, forming a dark stieak: muzzle punctate. Large specimens 

 with a large dark patch on the last rays of dorsal, as in C. monaclius 

 and the species of Codoma : base of dorsal fin with dark points. Cheeks 

 and opercles silvery. 



In the spring, the male fishes are profusely tuberculate on the head 

 and neck, and the fins are flushed with crimson. Teeth 1, 4-4, 3, hooked, 

 without masticatory surface. 



Tbe largest specimens taken were nearly three inches long, but most 

 were less than two. 



This species is abundant in Sahula River. It appears to be distinct 

 from C. labrosus, that species having larger scales and some other points 

 of difference. C. labrosus, monaclius, and zanemus differ from their con- 

 geners in the backward position of the dorsal and in the greater devel- 

 opment of the lips. 



24. CERATICHTHYS LABROSUS Cope. 



Ccratichthys labrosus COPE (1870), Proc. Am. Philos. Soc. 458. 



Professor Cope found this species not uncommon in the upper waters 

 of the Catawba. We did not find it in the Saluda or the Ennoree. 



25. CERATICHTHYS HYPSINOTUS Cope. 



Ccraticlilhys hypsivotw COPE (1870), Proc. Am. Philos. Soc. 458. 



This species is not uncommon in the Saluda. Breeding males are 

 violet-tinted, and the fins are quite red. The head is more or less rosy 

 and tuberculate above. This species has a very small barbel, and might 

 easily be taken for a Hydroplilox of the rubricroceus type.
