35. Cekatichthys labrosus, Cope. 



Spec. nov. 



This is a peculiar species of slender i)roportions. The top of the head 

 is gently decurved to a muzzle which scarcely overhangs the thick, pro- 

 jectile upper maxillary arch. The mouth is entirely horizontal, and the ex- 

 tremity of the maxillary bone attains the line of the orbit. The latter 

 enters the length of the head 3.75 times, and is just exceeded by the inter- 

 orbital width. The head enters length to origin caudal fi'om 4 to 4.5 

 times. Front arched in transverse section. Depth 5.5 times in length. 

 The dorsal line is nearly plane, and the elevation of the first dorsal rays 

 is contained twice in the length from its base to the anterior rim of the 

 pupil: it stands over origin of ventral. Scales large 6 — 34-5 — 4. Radii

This fish is silvery from the middle of the sides downwards. Tn some 

 specimens there are numerous blackish scales above the lateral line, which 

 are arranged so as to form indistinct cross-bars in life; in other specimens 

 the color is quite transparent, indicating two varieties. The latter are 

 frequently a little more slender than the former. 



The beards of this species are relatively longer than in any other spe- 

 cies of the genus. The prominent lips remind one of Phenacobius. The 

 species is not uncommon on the bottom in clear and rapid creeks which 

 flow into the upper waters of the Catawba River, in Macdowell and Burke 

 Counties, IST. Ca. 



36. Cekatichthys hypsikotus, Cope. 



Spec. nov. 



This little species has a stout robust form. The head and muzzle are 

 broad and flat; the muzzle is not pi'ominent; the mouth is inferior and 

 horizontal; the maxillary just reaches the line of the orbit. The form is 

 characterized in the genus by the gradual elevation of the dorsal line to 

 the base of the first ray of the dorsal fin, and its rather abrupt descent 

 from that point. The base of this fin is thus oblique and the distal out- 

 line is vertical; the posterior ray being less than half as long as the ante- 

 terior. This produces a characteristic appearance. The head is short 

 and enters the length 3.75 times, equalling the depth. Body compressed. 

 Orbit 3.5 times in length head, and once in inter-orbital space. Lips, es- 

 pecially inferior, thin; beards small. Scales, 4-5 38-41 3. Teeth
