a separate genus (Eudorcas), recognises (Sitz.-Ber. Ges. naturf. Freunde, 

 Berlin, 1910, pp. 106-124) no less than thirteen local forms, which 

 are regarded by him as species, although they are, at most, no more 

 than races. Their names are (i) G. t. baringoensis, Lakes Baringo 

 and Solei ; (2) t. naJiuroensis, Lakes Nakuro, Naivasha, and Elmenteita ; 

 (3) /. biedermanni, Shirati district; (4) t. langheldi, Usukuma ; (5) 

 /. schillings!) from Lake Natron to Kilimanjaro ; (6) /. njiriensis, west 

 side of Njiri Swamp ; (7) t. sabakiensis, east side of same ; (8) t. 

 bergeri, Nairobi ; (9) t. mundorosica, Mundorosi plains; (10) t. typica, 

 south of Kilimanjaro; (11) /. wembaerensis, Wembare plains; (12) t. 

 manyarae, Lake Manyara ; (13) t. ruwanae, Ruwana plains. Of these 

 either No. 5 or No. 10 is probably identical with Dr. Lonnberg's 

 nasalis ; Mr. Meyer regarding British East Africa as the typical 

 locality of the species, whereas Dr. Lonnberg considers that this position 

 is occupied by the Kilimanjaro race. 



Apart from certain skull-characters, the races recognised by Dr. 

 Meyer are mainly distinguished by slight differences in the colour of 

 the hair and shape of the horns. As it would occupy too much space 

 to record their differences, and as the number of races may prove to 

 be excessive, the quotation of the names must suffice. 



THE BEISA 



(Page 284) 



The beisa of the Laikipia plateau, British East Africa, has been 

 described by Mr. N. Hollister (Smithsonian Misc. Collections, vol. Ivi. 

 No. 2, p. 7, 1910) as Oryx annectans, as it appears to form a link 

 between the typical representative of the species and the fringe-eared 

 Kilimanjaro race. It is, however, only a local race, and should be 

 known as O. beisa annectans. 



THE SABLE ANTELOPE 

 (Page 290) 



On page 35 of Dr. J. E. Gray's "Catalogue of Ruminant 

 Mammalia in the British Museum," 1872, reference is made to a 

 variety of the sable antelope, for which the name kirki was suggested. 

 Its supposed distinctness was based on a statement by Sir John Kirk in 

 the Proceedings of the Zoological Society for 1864, that in the Batoka 

 Hills, to the north of the Zambesi, all the sable antelope are rufous.
