 The Asia. 



Several coloured drawings of adult and young fishes. Two stuffed 

 specimens. 



22. Oreinus hodgsonii. 



The Long-nosed Asia. 



Three coloured drawings and one stuffed specimen 21 inches long. 

 D. 2/7, A. 7. Snout much produced, longer than the part of the 

 head behind the orbit. The height of the body is one-fifth of the 

 total length (the caudal fin not included), the length of the head 

 one-fourth. Scales very small. The dorsal fin is short and elevated, 

 rather higher than the body below ; the second spine is very strong, 

 serrated posteriorly*. The origin of the dorsal fin is exactly on the 

 middle between the extremity of the snout and the base of the caudal 

 fin ; base of the ventral below the middle of the dorsal. Coloration 

 as in the common Asia (^Oreinus maculatus}. 



23. Oreinus, sp. 



Two coloured drawings and pencil sketches of the mouth. 



We are not able to refer this fish to a known species ; it appears 

 to be allied to Barbus diplocheilus of Heckel (Fische v. Kaschmir, 

 t. 10. f. 1), having a similarly serrated upper lip ; but the Nepalese 

 species is more elongate, has somewhat smaller scales, and the snout 

 considerably more produced. The greatest depth of the body equals 

 the length of the head, and is one-fifth of the total (the caudal fin 

 not included). The dorsal fin is somewhat higher than long and 

 than the body below, and occupies nearly the middle of the back ; 

 the ventral is inserted below the hinder third of the dorsal fin. The 

 figure shows nine dorsal and five anal rays. Brown above, each 

 scale with a dark dot, the dots being very well marked on the back 

 of the tail. The lower parts silvery. 



24. Oreinus, sp. 



One coloured drawing and sketches of the mouth. 



This is a third species which we believe to be new, but we abstain 

 from naming it as long as we have no actual specimens for exami- 

 nation ; the scales are of moderate size, larger than in any of the 



* This spine is injured in the specimen, but its size may be clearly seen in the 

 drawings.
