and root of the ventral fin, 16-18 round the caudal 
peduncle; the two rows above the lateral line the 
largest; scales of the lower part of the abdomen small 
or rudimentary. Dorsal III, 10, its origin equidistant 
from tip of snout and base of caudal; third simple 
ray moderately strong, serrated in its basal half, 2 
to s the length of the head and 11 as long as the last 
branched ray, free edge of the fin straight. Anal III, 
6-7, the second branched ray a little longer than the 
first or the third and twice as long as the last, as long 
as or little longer than the longest dorsal ray. 
Pectoral, a little shorter than the head, extending 2 
or sof the distance from its base to the base of 
ventral. Ventrals originating below the first branched 
ray of dorsal, extending nearly to the origin of anal. 
Caudal forked. Caudal peduncle 11 to 13 as long as 
deep, its last depth not more than : the length of 
head. Greyish above, silvery below, fins pale or some- 
what dusky. 
Two specimens 70 and I10 mm. in total length. The larger 
with tubercles on the snout and on the rays of 
the anal fin. 
Cyprinion kirmanensts, Nikolski, 1899, appears to be allied to 
this species, but differs at least in the larger eye, the 
thick and strongly serrated Jast simple dorsal ray, the 
form of the dorsal fin and the coloration.” 
The lateral scales agree fairly well with Cockerell’s ' descrip- 
tion of those of other species of the genus but differ in having 
ill-developed radii on the basal part and in lacking tubercles 
between the radii. The base resembles that of his figure of the 
scale of S. muscatensis. ‘Those on the ventral surface are entirely 
buried in the skin. They all appear circular on the surface, but 
the larger ones are sub-triangular, the distal end being produced 
and bluntly pointed. The smallest ventral scales are transversely 
oval and have the nucleus nearly central. Their basal radii are 
well developed. A large scale from the row above the lateral line 
has the following measurements:—length 3°9 mm., breadth 4:2 
mm., distance of nucleus from base o°8 mm. ; in a sub-triangular 
ventral scale they are, length 1'7 mm., breadth 1°8 mm., distance 
of nucleus from base 05 mm.; ina small transversely oval ven- 
tral scale, length 1-1 mm., breadth 1°3 mm., distance of nucleus 
from base o°5 mm. 
Only two specimens are known, both collected by the Seistan 
Arbitration Commission in the delta of the Helmand. We have 
examined the larger of the two, which 1s preserved in the Indian 
Museum. ‘The tubercles on its snout and fins referred to by Regan
