Fishes of the Yangtszc-Kiang. 431 



Eye rather small, shorter than the snout, one fifth of the 

 length of the head, and exceeding the width of the interorbital 

 space. Head rather compressed and higli behind, with broad 

 snout, and with the lower jaw prominent. The maxillary 

 extends to the vertical from the front margin of the orbit. 

 Gill-membranes attached to the median line of the isthmus. 

 Vertical fins lower than the body ; caudal fin rounded, equal 

 in length to the pectorals, which are three fifths of the length 

 of the head. Light-coloured, with broad, indistinct, darker 

 cross bands on the sides. Dorsal and caudal fins indistinctly 

 spotted with brown ; no spot at the base of the pectoral fin. 



This species, of which there is only one specimen in the 

 collection, 2\ inches long, is allied to Eleotris potamophila^ 

 but readily distinguished from it by its narrow, scaleless, 

 interorbital space. I do not know of any other species of 

 this genus extending equally high up in fresh water. 



Crossochilus monticola. 

 D. 11. A. 8. L. lat. 42. L. trans v. 7/7. 



Lips not fringed, the lower with a firm, sharp, horny cover j 

 four barbels, of which the lower are nearly as long as the 

 eye and the upper minute. The height of the body is two 

 sevenths and the length of the head two ninths of the total 

 length (without caudal). Eye of moderate size, two ninths 

 of the length of the head, two thirds of that of the snout, 

 and rather more than half the width of the interorbital 

 space, which is convex. Snout obtuse in front, with pits in 

 which probably horny tubercles are secreted during tlie 

 breeding-season. Mouth transverse, inferior. The origin of 

 the dorsal fin occupies nearly the middle between the end of 

 the snout and the root of the caudal ; root of the ventral fin 

 opposite to the fourth, fifth, and sixth dorsal rays ; pectoral 

 fin a little shorter than the head, reaching nearly to the origin 

 of the dorsal fin. Four longitudinal series of scales between 

 the lateral line and the root of the ventral fin. Caudal fin 

 deeply cleft, as long as the head. Coloration uniform. 



A single specimen, 7 inches long, was obtained by A. 

 Henry, Esq., in a mountain-stream fiowing into the Ichang 

 gorge of the Yangtsze River. 



Pseudogohio productus.
