4. Schizothorax progastus (McClell,). 



McClell., Ind. Cypr., pp. 274, 343, pi. 40, fig. 4. 



Hah. — Lake Tali Fu, Yunnan. 



One female specimen (damaged). 



Reported from the Himala^^as, from the headwaters of the 

 Ganges to Sadi3'a in Upper Assam. This species has not been 

 before reported from Yunnan ; l)Ut Yunnan is separated onty by 

 the district of Kachin (Upper Burma) from the mountainous 

 districts of Upper Assam whence the species was first reported. 



5. Labeo yimnanensis , sp. nov. 

 (Plate i, figs. I, la, ib.) 



Br. iii ; D. Ill 11 ; P. 17 ; V. 9 ; A. II 5 ; C. 19 ; L.l. 43. 



Length of head 4 J, height of body 3 J, length of middle 

 (shortest) rays of the caudal fin 12^ and outer (longest) rays nearly 

 4, and the length of caudal peduncle (the distance between the 

 posterior root of anal fin and the middle of the root of caudal) is 

 contained 4 times in the total length. 



Shape. — Dorsal profile almost a straight line from the end of 

 snout to the nape except for two slight concavities, one just above 

 the snout and the other a little behind the orbit. From the neck 

 to the anterior root of dorsal fin the profile is highly conv^ex, from 

 the anterior root of the dorsal fin to the root of the caudal the 

 profile is concave the concavity being very deep over a black 

 blotch on the middle of the caudal peduncle. The ventral profile 

 is almost a straight line from snout to cloaca, but from cloaca to 

 caudal it is somewhat convex though the curvature has no corres- 

 pondence to the concavity of the upper side. 



Snout. — Short, compressed and rather pointed but not project- 

 ing beyond the jaws, the terminal portion mostly covered with 

 tubercles. 



Barbels. — None, but flat thin processes or flaps like stumps 

 of barbels are found hanging inside at the angles of the mouth. 



Eyes. — Adipose circular eyelids, 3^ diameters in the length of 

 the head, i^ diameters from the end of snout and little less than 

 2 apart. Interorbital space slightly convex. 



Lips. — Loose in the mouth which is inferior, semioval and 

 less than one-third in the length of the head ; the inner double fold 

 of the hp is cartilaginous. The upper lip is cut in edges. 



r^c^/^.— Pharyngeal 5, 4, 2 ; 2, 4, 5. The size of an individual 

 of the outermost row is i| of each of those in the middle row and 

 double of each of the inmost row. 



Air-bladder. — Thick and large, divided into two unequal 

 chambers by a constriction, the anterior being the shorter and 

 much the broader of the two. 



Fins.— The dorsal arises three scales anterior to the vertical 

 from the ventral, and twentj^-two scales behind the nape and much
