16, GaZELLA THOMSONl. 



Thomson's Gazelle does not, I believe, extend beyond a few miles 

 north of Lake Nakuru. The average weight of a buck is 52 lbs. 



The females are liorned, whatever others may say to the contrary. 

 The horns run up to about 6 inches, but are for the most part mal- 

 formed and uneven. 



17, HipPOTEAGTjs BAKEBi, Heuglin. 



Captain F. S. Dugmore, now in Kikuyu, killed a bull of this 

 species on the Athi plains. He appears to be quite positive that 

 it is a Eoan of some sort. In April last, two marches from here, 

 I saw a herd of 7 antelopes much resembling the Eoan. They 

 were about 800 yards oflf, and I had a good look at them with a 

 powerful telescope before commencing a stalk, which, I regret to 

 say, was unsuccessful through one of them, that I did not notice, 

 seeing me. There were four cows, one bull, and two half-grown 

 calves. In colour they were like an Oryx, and not unlike it in 

 shape, thougli larger and longer on the leg. The back of the 

 neck was arched, like a Sable, and appeared to have a short dark 

 zebra-like mnue. The ears were very long and tufted, and the 

 horns of both the bull and cows were thick in proportion to their 

 length, the bull's perhaps 20 inches or more, and curved backwards 

 like a Roan, With the exception of one calf they were all standing 

 under a big tree in the shade, and as they were all broadside on 

 to me I could not make out what the facial markings were like. 

 As the calf stood facing me, its ears stood out almost at right 

 angles to its head, with a slight droop towards the tips. They 

 appeared to me to be not large enough for Eoan (I have only 

 seen those in the Natural History Museum), and I believe that 

 they are more likely to be H. hcikeri. I feel sure that they are of 

 the same species as that I saw on the northern slopes of Mount 

 Elgon in 1890. 



18, Oryx eeisa. 



This is a new find for me. It ranges as far south as a point 

 due east of this Station, i. e. about on the Equator. Lt. G. E. Smith, 

 E.E., saw a herd of 8 a few days ago. At Baringo I shot 7 in 

 September. There is no doubt whatever about their being true 

 0. beisa. I do not believe the 0. callotis ranges even so far north as 

 the Athi plains. Three bulls that I killed weighed (whole with a 

 scale up to 1000 lbs.) 383 lbs., 355 lbs., and 458 lbs., and a cow 

 weighed 380 lbs. 



19, Steepsiceros zudu. 



The Kudu is found here on Mau, but is y&cj scarce. 



20, Stbepsiceeos imbeebis, Blyth, 



The Lesser Kudu, though found on Kilimanjaro, does not, I 

 think, range much farther north, excepting along the coast, and 

 I do not believe that it extends west of Mount Kenia.
