28 THE ANTELOPES IN 



the Cape Colony : it is therefore of no little interest to state 

 that there are in the Leyden Museum four specimens from 

 the Cape, among them an adult and a nearly adult female 

 collected by Dr. von Horstock : as the latter collected in 

 Uiteuhageu, Caledon and Steenbergen we may be sure 

 that our specimens once lived in the Cape Colony, perhaps 

 the latest survivers from there. 



Although it seems that albinos are not frequently met 

 amongst the Antelopes, it may be mentioned that euchore 

 makes exception as there are of this species three instances 

 known: P. a specimen in the Paris Museum, described in 

 1827 by Mr. Hamilton Smith in his » treatise on the order 

 Ruminantia", 2°. the specimen mentioned in the »Johan- 

 nesburg Times" of January 22"'^, 1897 and caught in 

 the Orange Freestate, at that time exhibited in Johannes- 

 burg by Messrs. Colquhoun and Hill of Jeppe street (cf. 

 the Book of Antelopes, HI, p. 62) ; it is unknown where 

 this specimen is at present, and 3°. a specimen in the 

 Leyden Museum, collected by Dr. von Horstock, mentioned 

 in my Catalogue of the year 1892 as »femelle passablement 

 adulte montee, au teint du pelage tres pale". 



In the Leyden Museum there is a female-specimen from 

 the von Horstock's collections with abnormal horns: they 

 measure along the curves 10.3 cm., are straight for their 

 greatest length and only towards the tip curved or hooked 

 backwards like the Chamois' horns ; of rings there is about 

 no trace to be seen (cf my Catalogue, p. 169). 



Gazella leptoceros (Cuvier) and 

 Gazella Loderi Thomas. 



In the »book of Antelopes" (T. Ill, p. 147) the authors 

 stated: »the identity of the Egyptian Gazella leptoceros 

 with the Algerian G. Loderi is perhaps not yet exactly 

 certain, although we have combined the English name of 

 the latter with the scientific name of the former. On com- 

 paring specimens from Tunis and Algeria with others from
