Mr. 0. Thomas on the Dwarf }[un(joose, 377 



Abyssinia, and Kordofan, which, however, has more sleiulcr 

 horns, with more distinct rings, reaching ahiiost round, a 

 broader forehead, and a generally paler coloration. The 

 horns also diverge much more in D. tora^ as shown at a glance 

 by the distances between the tips of the horns, as recorded in 

 R. Ward's ' Horn Measurements.' B. Neumanni has evidently 

 nothing to do with Acronotus lelwel, Heugl. {lieise N.O.-Afr. 

 ii. p. 124), in which the tips of the horns point straight out- 

 wards. ]\iatscliic has referred A. lelioel to the West-African 

 IJubal, but ISclater and Thomas have more correctly placed it 

 among the synonyms of B. huselaphus. 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., ? 183; total length 

 along the curves, ^ 420, ? 345 ; tip to tip, ^ 206, ? 249. 

 The rings of the horns are not very prominent and do not 

 reach all round. 



Breadth of skull at forehead, J 100 millim., ? 80; length 

 of skull from base of horn to upper lip, along the side in a 

 straight line : ^ 430, ? 403 millim. 



Colonr of hair fulvous fawn, much richer on the back, 

 where there are also some darker spots, which may be stains 

 or natural; below very much paler. Chin blackish, tip of 

 tail black. Tiie male is brighter and darker in colour than 

 the female. There are also on tlie back some patches with 

 longer, thicker, almost whitish-buff hair, perhaps remains of 

 the winter fur. 



XLV. — On the I) loarf Mungoose (Helogale) of Sonialiland. 

 By Oldfield Thomas. 



The recent presentation to the British jMuseum of a Helogale 

 obtained by Dr. A. E. Atkinson when with Lord Delaniere's 

 shooting-party in Somalilaud has enabled me to examine 

 more carefully the characters of this mungoose, which has 

 been assigned by lihoads * and Elliot f to H. undulata, 

 Peters. The specimens referred to by both these authors had 

 passed through London and been provisionally referred to
