very smail, but those at the base of the dorsal fin are a little 
larger. Those near the lateral line are of intermediate size. 
Towards the tail all the scales are poorly developed and hard to 
distinguish. The lateral line runs along the middle of the caudal 
peduncle, then slopes gradually downwards, proceeds along the 
body well below the middle and finally slopes upwards just behind 
the head, along the top of which it runs to the tip of the snout. 
The colour is bluish above and silvery on the belly and sides 
There are sometimes a few small black spots on the latter.

The species was described from Waser in the eastern 
district of the great mass of mountains that occupies northern 
Baluchistan anda great part of Afghanistan. A few specimens, the 
longest of which is 48 mm. long without the caudal, have been 
found among large numbers of young Sehizothorax zarudnyt 
and of Discognathus adiscus from the following localities :—a small 
pool connected in the flood-season with an effluent of the Helmand 
in the desert a few miles south of Nasratabad; pools in the 
dry bed of the Randa stream in the same district a few miles 
N.E. of the ruined city of Jellalabad ; a still, reedy channel leading 
from the Hamun-i-Seistan on the road between Lab-i-Baring 
and Nasratabad. The largest specimens, which were alone di. 
tinguished at the time, are from the last locality. Their fin-rays 
were extremely brittle and unfortunately the caudal was broken 
in all those obtained but one. These specimens were collected 
in November and December, 1919. 
Since drawing up this description we have been able to com- 
pare our specimens with one of the types of the species, received in 
exchange by the Z.S.I. through the courtesy of Mr. Tate Regan 
and the Trustees of the British Museum. Though the proportions.
