Dr. Abbott remarks on one of the labels that the species is common 
in the forest, and that the natives state that there are three other kinds 
in the same region, one larger and two smaller.

Helogale undulata (Peters). 
The two skins collected agree perfectly with Peters’s deseription and 
figure, though the latter is too highly colored. The dimensions of the 
younger skin (No. 18934), which is the only complete one, are as follows:

The hairs of the under surface of the tail in the older skin are nearly 
uniform red throughout, but in the younger skin they are annulated 
throughout with black, except at the base of the tail. 
The dimensions of the skulls are as follows:

* For convenience of comparison I use here and in Herpestes the measurements given by Mr. Old- 
field Thomas in his paper on the African Mongooses. (Proc. Zool. Soc., London, 1882, p. 65.) 
“Length "—Distance from front of premaxillw to most posterior point of either occipital condyle. 
t Greatest breadth across zygomata. 
{ From front of premaxillz to end of bony palate. 
§ Between the points at which the last premolar and first molar touch each other at the outer edges. 
|| From front of premaxille to a point midway between those mentioned under last heading. 
{] From central point of post. edge of basi-occipital to anterior edge of lower surface of preesphenoid. 
The ratio between the breadth of the last premolar and last molar 
teeth, measured according to Mr. Thomas’s system, is 72 per cent. for the 
adult skull (No. 35095), and 66 per cent. for the young skull (No. 35094). 
The difference is due to the wearing away of the last premolar in the 
older skull, which is here absolutely smaller than in the younger skull. 
Dr. Abbott remarks that this species is common, living in holes in 
ant-hills.

Herpestes gracilis Riippell. 
The single specimen collected by Dr. Abbott appears unquestionably 
to belong to this species, although it agrees exactly with neither 
the descriptions nor the figures of the typical and other varieties. This 
is due probably to the indefiniteness of the terms used in the several
