226 MR. F. DAY ON THE FISHES OF AFGHANISTAN. [Apr. 6, 



Indus, where this fish exists. M'Clellaud, however, gives it as 

 C. checkra, and Afghanistan and Punjab examples as identical. 

 Two specimens were sent to Europe, one of which (young) is in the 

 British Museum, and is C. checkra = C. bimaculatus, Bloch, but 

 with a smooth pectoral spine, and may be the Afghan fish as labelled. 

 If so, we have two species of Callichrous in Afghanistan. 



CiRRHiNA LATiA, Ham. Buch. 



Cyprinus gohania and ? sada, Ham . Buch . Barbus diplocheilus and 

 Tylognathus barbatulus, Heckel. Gonorhynchus Jimbriatus, macro- 

 stomus, and brevis, M'Clelland. Chondrostoma wattanah, Sykes. 

 Crossocheilus rostratus, Giinther. 



Among Dr. Duke's Quettah fishes are several of this species, but 

 in a very bad state. There are three excellent examples sent by 

 Colonel Miles from Gwadur, 5^, 3|, and 3| inches respectively in 

 length. The upper lip is not so deeply indented as observable in 

 some Himalayan examples ; there is only a single pair of rostral 

 barbels, and four and a half rows of scales between the lateral line 

 and the base of the ventral fin. 



This fish has much the appearance of a Discognathus (which is 

 likewise termed Gonorhynchus by M'Clelland), adhering to stones in 

 the beds of rivers, as I had an excellent opportunity of observing 

 when investigating the fish-fauna of the Beluchistan range of hills. 

 It is subject to numerous modifications ; the rudiment of a pad is 

 present behind the lower lip, in the situation where the sucker exists 

 in Discognathus ; while the two have the same proportions and the 

 identical number of rays and scales. Consequently one being taken 

 for the other is a not unlikely error. Still, as D. lamta is found from 

 Syria to Abyssinia and through the Himalayas and India, it is to be 

 supposed that it is present in Afghanistan. 



Cirrhina latia is very generally distributed from Sind throughout 

 India, excepting south of the Kistna river and the Malabar coast. 

 It is common along the Himalayas, where it attains as much as 

 8 inches in length. It now appears that it extends along the Belu- 

 chistan hills to Quetta, and also along the Meckran coast to Gwadur. 



The genus Scaphiodon of Heckel appears to be well repre- 

 sented, as might have been anticipated, it being a Western Asiatic 

 form which extends along the Meckran coast and the Beluchistan 

 range of hills to the Punjab, Sind, and down the Malabar coast. 



Scaphiodon irregularis. Day. 



This species I originally obtained in the Beluchistan range of 

 hills, at an elevation of 3500 feet. Among Dr. Duke's fishes I find 

 nine examples of it up to 6| inches in length, thus giving me the 

 opportunity of supplementing my original description. The pharyn- 

 geal teeth are plough-shaped, 4, 3, 2 | 2, 3, 4. The gill-rakers are 

 short and somewhat wide apart. Pseudobranchiae present.
