The eggs of this species are very small and almost fill the 

 whole ot the abdominal cavity. 



Diplophysa papilloso-labiata is known only from the Tarim 

 river-system (Eastern Turkestan). The longest specimen in our 

 collection is 105 mm. in length without including the length of 

 the caudal fin.

This species is represented in our collection by several young 

 and half-grown specimens. It closely resembles Nemachilus lhasae 

 Regan with which Annandale and myself ' confused it when 

 dealing with the fish of Seistan. Both Lloyd and Stewart referred 

 these specimens along with Nemachilus lhasae to N. stoliczkae. 

 Diplophysa stewarti is, however, readily distinguished by the pre- 

 sence of a second air-bladder and also by the nature of its skin, 

 which is tuberculate all over. 



The dorsal profile is highest near the nape, in front of which 

 it slopes considerably to the tip of the snout. The body is thickest 

 anteriorly and gradually and regular \y slopes to the base of the 

 caudal fin. The head is round, narrow and pointed ; its length is 

 contained 4'2 times in the length of the fish without the caudal 

 fin. The body is deepest at its commencement and the greatest 

 depth of the body is contained i'6 times in the length of the head. 

 The eyes are placed in the middle of the head and are scarcely 

 visible from below ; the diameter is contained 3^4 to 3*7 times in 

 the length of the head There are six barbels, 4 rostral and 2 

 maxillary. The maxillary barbels are the longest ; they are 

 slightly longer than the diameter of the eye. The upper lip is 

 fringed and the lower is interrupted in the middle and is strongly 

 papillated. The lateral line is complete ; anteriorly it is continued 

 as a series of open pores below the eyes. There are a few open 

 pores on the dorsal surface of the head near its posterior border 

 extending downwards on each side to join the lateral line. The 

 dorsal fin commences considerably in advance of the ventrals and 

 its origin is equidistant from the tip of the snout and the base of 

 the caudal fin. It is higher than the depth of the body immed- 

 iately below it. The ventrals extend beyond the anal opening and 

 almost reach the base of the anal fin. The caudal peduncle is long 

 and narrow; its least height is contained 6'i to 6 6 times in its 

 length. The caudal fin is deeply concave with the upper lobe 

 considerably longer than the lower.
