1892.] MR. O. THOMAS ON A NEW ANTELOPE. 195 



Pairings took place, and for the first time I succeeded in rearing the 

 larvae and obtaining a second hrood of this species. The larvae were 

 very handsome and were reared upon whitethorn. I also succeeded 

 in rearing the larvae of Eaeles imperialis, and the pupse (3) in the 

 Insect-house are alive and healthy. I had also the larvae of Eaeles 

 recalls, but these I did not succeed in rearing. 



Owing to the cold and wet summer of last year collecting was 

 very difficult, and many species which I have generally easily ob- 

 tained are absent from this list in consequence. 



Mr. Sclater exhibited a flat skin of the Wild Ass of Somali-land 

 {Equus asinus somalicus), taken from a specimen shot by Mr. J. D. 

 Inverarity, about fifty miles from Berbera, about eighteen months 

 ago, and made the following remarks : — 



" Mr. Inverarity has kindly sent me the skin of the Wild Ass of 

 Somali-land (Equus asinus somalicus), which I now exhibit. It will 

 be observed that the present specimen differs from that previously 

 described and figured (P. Z. S. 1884, p. 542, pi. 50) in having slight 

 shoulder-stripes, as well as a dorsal stripe. The shoulder-stripe on 

 the off side is the more distinct of the two. The general colour of 

 the skin is also not of so deep a grey tint. All the four feet are 

 banded as in the former specimen." 



Mr. Henry Seebohm exhibited four examples (two males and two 

 females) of Pieus richardsi from the island of Tsu-sima in the Straits 

 of Corea, and pointed out that one of them had more white at the 

 tips of the primaries than has yet been found in examples from 

 Corea. As this is the only alleged difference between P. richardsi 

 and P. Jcalinowskii, the latter name, being the most recent, must be 

 henceforth regarded as a synonym of the former. 



Mr. Oldfield Thomas exhibited a mounted head of the East- 

 African Antelope hitherto referred to Oryx beisa, Riipp., but which 

 he considered to represent a new species. 



The specimen described was from the neighbourhood of Mount 

 Kilimanjaro, and had been generously presented to the National 

 Museum by Messrs. Rowland Ward and Co., of Piccadilly. 



The species was proposed to be called 



Oryx callotis, sp. n. (Plate XIV.) 



Size of 0. beisa ; horns as iu that species, but very slightly curved 

 backwards. Ears long, their tips sharply pointed, and ornamented 

 with a prominent black tuft, the hairs of which are from two to 

 three inches in length. Ground-colour of face between the black 

 markings rich fawn, as dark as the sides of the neck, except just 

 round the muzzle, where the colour is white. Arrangement of mark- 

 ings much as in 0. beisa, except that the black line passing through 

 the eye runs further down under the throat and in some specimens.
