Abyssinia, and Kordofan, which, however, has more slender 
horns, with more distinct rings, reaching almost round, a 
broader forehead, and a generally paler coloration. The 
horns also diverge much more in B., tora, as shown at a glance 
by the distances between the tips of the horns, as recorded in 
R. Ward’s ‘Horn Measurements.’ 3B. Newmanni has evidently 
nothing to do with Acronotus lelwel, Heugl. (Reise N.O.-Afr. 
i. p. 124), in which the tips of the horns point straight out- 
wards. Matschie has referred A. lelwel to the West-African 
Bubal, but Sclater and ‘Thomas have more correctly placed it 
among the synonyms of B, buselaphus. However, a query 
should be added to the name, the description not being exact 
enough to make out what the name means. The type is not 
in the museum at Stuttgart, according to kind information 
of Prof. Lampert, nor can it be found elsewhere at present. 
The horns of B. Neumanni measure as follows :— 
Circumference at base, § 273 millim., 9 183; total length 
along the curves, g 420, 2 345; tip to tip, g 206, 2 249. 
The rings of the horns are not very prominent and do not 
reach all round. 
Breadth of skull at forehead, g¢ 100 millim., ¢ 80; length 
of skull from base of horn to upper lip, along the side in a 
straight line: g 430, 2 403 millim. 
Colour of hair fulvous fawn, much richer on the hack, 
where there are also some darker spots, which may be stains 
or natural; below very much paler. Chin blackish, tip of 
tail black. The male is brighter and darker in colour than 
the female. There are also on the back some patches with 
longer, thicker, almost whitish-buff hair, perhaps remains of 
the winter fur. 
XLV.—On the Dwarf Mungoose (Helogale) of Somaliland. 
By OLpFIELD THOMAS. 
THE recent presentation to the British Museum of a Helogale 
obiained by Dr. A. E. Atkinson when with Lord Delamere’s 
shooting-party in Somaliland has enabled me to examine 
more carefully the characters of this mungoose, which has 
been assigned by Rhoads* and Elliott to H. undulata, 
Peters. ‘The specimens referred to by both these authors had 
passed through London and been provisionally reterred to
