NO. 2 MAMMALS FROM BRITISH EAST AFRICA — HOLLISTER 3 



of such minor horn characters, as a large series would evidently 

 show considerable variation in the angle of the terminal section 

 of the horn. 



The measurements of this skull (No. 155431) are: Condylobasal 

 length, 426 millimeters; palatal length, 241; greatest breadth, 138; 

 facial length, 438: muzzle to orbit, 312; upper tooth row, 100; length 

 of horns, 553: circumference at base, 304; greatest spread, 250; 

 spread at points, 112; length of smooth backward terminal section, 

 210. 



The skin of the head is a rich red in color with a faint stripe of 

 black down the back of the neck from between the ears to the point 

 where it was severed from the body. 



This hartebeest was very abundant on the Guas Ngishu Plateau,, 

 where hundreds were seen almost daily, in herds of from three or 

 four up to fifty or more each. Many other animals, especially the 

 zebra and topi, and sometimes the giraffe and eland, take advantage 

 of the abundance of the kongoni and graze among the herds, appar- 

 ently depending upon them to give the first alarm of approaching 

 danger. The breeding season for many of the British East African 

 ungulates appears to extend over the greater part of the year, and, 

 in large herds of Jackson's kongoni, young of several ages, from 

 small calves to nearly grown, were often seen. 



CONNOCH^TES TAURINUS ALBOJUBATUS Thomas 



Skin of head and neck to withers. Killed by Dr. Rainsford on 

 the Athi Plains, in December. Practically a topotype of albojubatus. 

 The color represents the dark phase and is much darker than in 

 any of six heads in the Museum collection from "Masailand," the 

 yellowish-white throat fringe being especially conspicuous. 



This animal was seen only in the Athi Plains country and appar- 

 ently does not occur on the Laikipia or Guas Ngishu plateaus. 



OREOTRAGUS OREOTRAGUS SCHILLINGS! (Neumann) 



In the collection presented by Mr, White were the feet of one of 

 these antelopes from the Laikipia Plateau. In his collection of 

 trophies Mr. White has two heads of old bucks which differ greatly 

 in color. One from Elmenteita has the head gray, with almost pure 

 white markings, while the head from the Laikipia country is every- 

 where deeply suffused with an ochraceous color, giving a very differ- 

 ent appearance to the animal.
