506 ON THE HORNS OF ANTILOPE TRIANGULARIS. [Apr. 21, 
2. A young male Markhoor (Capra megaceros), from the vicinity 
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 (Canis 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 (Hippotragus niger), from the Zomba Plains, 
of which the horns measured 39 inches along the curve; and a 
fine specimen of a peculiar form of the Brindled Gnu (Connocheetes 
gorgon), shot at the south end of Lake Chilwa by Mr. H. C. 
McDonald, of the British Central African Administration. This 
was believed to be the first example of the Guu sent home from 
British East Africa. 
Amongst the birds sent on this occasion (as kindly determined 
by Capt. Shelley) were examples of Girus carunculata from the 
Shirwa Plains, not previously transmitted from Nyasaland, and 
of Surcidiornis melanonota from Lake Shirwa. 
Mr. Sclater also exhibited a fine pair of horns of the so-called 
Antilope trianqularis (Gunther, P. Z. 8. 1889, p. 73), Doratoceros tri- 
angularis (Lydekker, Ann. & Mag. N. H. (6) viii. p. 192; id. 
‘ Field,’ Ixxviii. p. 130 (1891)), belonging to Mr. Justice 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 triungularis 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, Oreas canna, 
I see nothing whatever to negative the idea that they are abnormal 
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 Tragelaphine.—P. L. 8.]
