1872.] DR. GUNTHER ON BARBUS BEAVANI. 875 



fawn-colour. Tail of the same colour as the back, of moderate 

 length. Temporal gland, knee-brushes, and false hoofs absent. 

 Ears very long. Horns long and rather slender. 

 Hab. South Africa. 



2. Nanotragus montanus (Riipp.). 



Sandy fawn. Tail of the same colour as the back, and very short, 

 almost rudimentary. Temporal gland and knee-brushes distinct. 

 False hoofs small. Ears moderate. Horns short and subconical. 



Hab. Abyssinia. 



3. Nanotragus nigricaudatus, sp. nov. (Plate LXXV.) 

 Grizzly fawn. Forehead rufous. Tail black, of moderate length. 



Temporal gland distinct, black. Knee-brushes large. False hoofs 

 present but small. Ears moderate. Horns slender, moderate in 

 length, and slightly bent forward. 



Hab. Gambia. 



Height at shoulder, 20" ; length of ears, 4|" ; length of horns, 3". 



A narrow mark about one inch in length on each side of the 

 naked muzzle, a line passing round the eye and suborbital pit, but 

 not meeting in front of the gland, lower lip, chin, spot on throat, 

 belly, inside of limbs nearly as far down as the carpal and tarsal 

 joints, and rump white. Nose and cars externally dusky brown. 

 Forehead and occiput rufous. Temporal gland large, round, and 

 covered with very short bluish black hair, that covering the region 

 between the suborbital pit and the eye being of similar character and 

 colour. Neck, back, flanks, and sides of a peculiar grizzly fawn-colour. 

 This peculiarity is obtained by the base of each hair being almost 

 white, the tip rufous, the intervening part of a deep bluish grey. 



In a letter which Mr. Mosse has kindly favoured me with, he 

 writes : — •" I procured this Antelope when two or three months old, 

 at Gambia, in March 1867 ; it was caught near the banks of the 

 river Gambia, about seventy or eighty miles from Bathurst, midway 

 between the latter and Macarthey's Island. I have not seen a similar 

 one since, either there or at any of the stations on the west coast." 



5. • Note on a hitherto unpublished Drawing in the 

 Buchanan-Hamilton Collection, representing Barbus 

 beavani. By Dr. Albert Gunther, F.R.S., F.Z.S. 



[Eeceived October 29, 1872.] 



Through the kindness of Mr. J. Wood-Mason, I have received an 

 "accurate tracing in pencil of the drawing" in the Library of the 

 Asiatic Society of Bengal, bound up with the original drawings of 

 Buchanan Hamilton, and mentioned in the Proceedings of this 

 Society, 1871, p. 764. This drawing had been stated to represent 

 the Cyprinus chagunio (B.H.), and to afford the evidence that 

 Barbus beavani (m.) was the same fish (P. Z. S. 1871, p. 637). 



In order to prove this assertion Mr. Day mentions particularly the 

 length of the barbels, which Hamilton has described as " minute "
