1901.] ON THE ANTELOPES OE THE WHITE NILE. 291 



spineless, and the spines begin only somewhat behind the line 

 that unites the bases of the inner margins of the ears ; whereas in 

 E. macracantJms the spines begin considerably in front of this 

 line. 



I give here the following description of an adult specimen of 

 this little-known species : — 



Size of a large E. europceus. 



Ears comparatively a little smaller than in E. auritus. Head 

 and upper part of neck whitish, with a rufous tinge on the upper 

 part of the head. The spines are very long, up to 43 mm., and 

 have a white base and two black and two white bands, and their 

 long black apex has a blue lustre which gives to the whole colour- 

 ing of this Hedgehog a very dark appearance. The fur behind the 

 ears and on the sides of the body is brownish ; the abdomen and the 

 feet are pure black. 



This Hedgehog has only been found in the country named 

 Ust-Urt, which lies between the Caspian and the Aral seas. At 

 present this is a quite out of the way place, distant from all roads. 

 This is the reason, I think, that it has not been visited for a very 

 long time by a naturalist, and that the animals described from 

 this country have been almost forgotten, e. g., Ovis arlcal Brandt. 



It is very likely that besides the above named species of 

 Hedgehogs, there will also be found in the Transcaspian province 

 E. megalotis Blyth, so common in Afghanistan. I may also state 

 tliat Zaroudnoi speaks of a Hedgehog found by him in the Tedgen 

 oasis and along the middle course of the Murgab (Bull. Nat. 

 Moscou, 1889), which, in its characters, according to this 

 author, does not agree with any of the species enumerated here. 

 Unfortunately I have not had the opportunity of examining 

 the specimens collected by him. 



2. Field-Notes on the Antelopes of the White Nile. 

 By Captain Henry N. Dunn \ 



[Eeceived May 29, 1901.] 



On putting together these few notes on the Antelopes of the 

 While Nile, I am merely giving information as to what I know 

 personally of their habits, and will speak only of those species 

 observed by myself, and that mainly, too, from a sportsman's point 

 of view. Not having my diary at hand, I am unable to give exact 

 dates. 



My only opportunity of shooting on the upper reaches of the 

 White Nile was when attached, as Medical Officer, to an expedition 

 formed for the purpose of clearing away the sudd-obstruction in 

 the Bahr-el-Jebel.
