606 ON THE DOBNS OP ANTILOPE TMANQULAEIS. [Apr. 21, 



2. A young male Markhoor (Ctipra mec/acerps), from tlie Ticinity 

 of Peshawar, British India, presented by Col. Paterson, 

 March 18th. 



3. A pair of a rather scarce species of Duiker Antelope 

 {Cephalophus coronatus), from West Africa, received in exchange, 

 March 23rd. 



4. A Silver-backed Fox (Cam's chama), from Cape Colony, 

 presented by C. W. Southey, Esq., of Culmstock, Schoombie 

 Station, South Africa. 



Mr. Sclater exhibited some of the specimens from Nyasaland 

 lately sent home by Sir H. H. Johnston, K.C.B., to be transmitted 

 to the British Museum. Amongst these was a very fine head of a 

 male Sable Antelope {ITipjMti-agus nir/er), from the Zoniba Plains, 

 of which the horns measured 39 inches along the curve; and a 

 fine specimen of a peculiar form of the Brindled Gnu (Connochcetes 

 f/orc/on), shot at the south end of Lake Chilwa by Mr. II. C. 

 McDonald, of the British Central African Administration. This 

 was believed to be the first example of the Gnu sent home from 

 British East Africa. 



Amongst the birds sent on this occasion (as kindly determined 

 by Capt. Shelley) were examples of Grus c.artmculata from the 

 Shirwa Plains, not previously transmitted from Nyasaland, and 

 of Sarcidiornis melanonota from Lake Shirwa. 



Mr. Sclater also exhibited a fine pair of horns of the so-called 

 Antilope trianr/tdaris (Giinther, P. Z. S. 1889, p. 73), Doratqceros tri- 

 anffuhris (Lydekker, Ann. & Mag. N. H. (6) viii. p. 192 ; id. 

 ' Field,' Ixxvili. p. 130 (1891)), belonging to Mr. J\istice Hopley of 

 Kimberley. Mr. Justice Hopley, who had purchased these horns 

 at Kimberley, stated that they were said to have been obtained 

 somewhere on the Zambesi. Mr. Sclater was of the opinion (which 

 was now generally prevalent) that they were abnormal horns of a 

 cow Eland. 



[P.S., April 24th. — Since I exhibited these horns I have compared 

 them with the typical specimens of Antilope triangxdaris in the 

 British Museum. There can be no doubt that both pairs belong 

 to the same species of Antelope, but Mr. Justice Hopley's pair 

 are not quite so long, rather more incurved backwards, and less 

 broadly spread ; they are also smoother at the base, showing but 

 slight appearances of corrugations. 



On comparing these horns, and the portion of the skull attached 

 to them, with the horns of the ordinary female Eland, Oicas canna, 

 I see nothing whatever to negative the idea that they are abnorn)al 

 horns of that Antelope, which for some reason or other have grown 

 without making the ordinary twist characteristic of Oreas and 

 other genera of the Tra(jelaplnn(s. — P. L. S.]
