Show 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 externally. Habitat. Dr. Duke sent two examples, 4 | and 5^ inches respectively in length, taken in April 1877 from a spring at Tral. Variety. Col. Miles sent me three examples, the largest being 5f 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 articulated. 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 preservation 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 following- Labeo ceeruleus, Day, L. diplostomus, Heckel, L.dyocheilus, M'Clelland, Scaphiodon watsoni, Day, Cirrhina latia, Ham. Buch., Botia geto, Ham. Buch. These fishes are all forms common in India, |
