1880.] MR. F. DAY ON THE FISHES OF AFGHANISTAN. 229 



the height of the anterior rays are equal to the length of the base of 

 the fin. Pectoral as long as the head, excluding the snout ; its rays 

 very stiff. Ventral inserted beneath the first divided dorsal rays ; it 

 is rather longer than the pectoral, but does not reach the base of the 

 anal. The anal commences slightly nearer to the ventral than to the 

 caudal fin ; if laid flat, it reaches the latter. Caudal forked, lower lobe 

 the longer. Scales : 5| rows between the lateral line and the base 

 of the ventral fin. Lateral line at first slightly concave, then 

 continued just to the centre of the base of the caudal. Colours : 

 steel-blue superiorly, becoming light on its sides and beneath ; body 

 covered with very fine black specks. Fins dusky, darkest ex- 

 ternally. 



Habitat. Dr. Duke sent two examples, 4| and 5| inches respec- 

 tively in length, taken in April 1877 from a spring at Tnil. 



Variety. Col. Miles sent me three examples, the largest being 

 .5| inches in length. They were taken from the river near Gwadur. 

 They differ from Dr. Duke's specimens in that there are more scales 

 between the lateral line and the base of the dorsal fin ; but on very 

 carefully comparing the specimens, it seems as if many of the scales 

 were subdivided into two, causing this variation ; its pectoral rays 

 are not so stiff ; and the eye is a little smaller. 



Barbus terio. Ham. Buch. 



The examples of this fish sent by Dr. Duke differ from the typical 

 form in that the last undivided dorsal ray is weak and partially arti- 

 culated. 



Nemacheilus ? 



Dr. Duke has sent several young examples of a species of this 

 genus ; but they are too small and in too bad a state of preser- 

 vation to render it safe to describe them, though they appear to me 

 to be of a species not as yet described, so far as I am aware. It is 

 probably identical with the form obtained by Griffith from the same 

 locality. It is banded with transverse bars of yellow rather wider 

 than the ground-colour, these bars taking on a somewhat angular 

 form near the tail. Col. Miles sent me several small ones of the 

 same species from the river near Gwadur. 



In the winter of 1871 I was engaged in investigating the fisheries 

 of Sind ; and from Larkhana I turned off to Ghaibi Dehra, and then 

 into the Beluchistan hills for the purpose of examining what species 

 exist in the streams. The first river reached was that at Sita, in 

 the vicinity of which place it disappears into the ground ; while, a 

 few miles further on, its origin is as sudden as its disappearance. At 

 this latter locality it is quite hot as it emerges from the earth, 

 while evidences of volcanic action are to be seen all around. In this 

 stream, which is largely impregnated with salt, I obtained the follow- 

 ing — Laheo cceruleus. Day, L. dij)lostomus, Heckel, L. dyocheilus, 

 M'Clelland, Scaphiodon watsoni. Day, Cirrhina latia, Ham. Buch., 

 Botia geto, Ham. Buch. These fishes are all forms common in India,
