(iii) The caudal fin is deeply emarginate. 



(iv) The chest and back are naked. 



(v) The proportions are different in the two species. 



Nikolsky described G. rossicus from the specimen which he 

 had previously referred to G. variabilis. Annandale and myself 

 in 1920 regarded Nikolsky's G. variabilis as a synonym of G. 

 phryne but overlooked his later paper ( [900) in which the speci- 

 fic name rossicus is proposed. I have now carefulh' compared the 

 descriptions of D. phryne and D. rossicus and do not think that 

 there is any difference between the two forms. In his Latin 

 description Nikolsky makes no mention of the scales on the chest 

 or on the back ; but considering that his specimens were obtained 

 from the same locality whence Annandale described his G, phryne. 

 I have no doubt that the two species are identical. 



I refer to this species the specimens collected by Aitchison 

 when he was attached to the Afghan Delimitation Commission. 

 These examples are not in good condition for detailed examina- 

 tion ; but so far as I have been able to make out the only differ- 

 ence between them and the G. phryne from Seistau lies in the 

 structure of the mental disc. In the Afghanistan examples the 

 free borders of the disc are well developed. 



I also refer to this species Col. MacMahon's specimens from 

 Seistan and several examples collected by v?ol. Alcock in the Shila 

 and Lora Rivers, Afghanistan. 



This species is fairly common in the hilly country of Baluchis- 

 tan but is rare in Seistan and Oriental Persia. 



The air-bladder, like the other less modified species of Garra . 

 is fairly extensive and is of the normal form. In a mature female 

 55 mm. in total length, the measurements are as follows: —
