This striking animal is apparently a desert representative 

 of the Banded Mungooses, being distinguished from all those 

 known by its pallid ground-colour, concolorous tail, and almost 

 obsolete stripes. Compared with other species it may, in addi- 

 tion, be distinguished from C. zebra by its larger size and 

 the absence of rufous in the coloration of the under surface. 

 This latter character also separates it from C. gothneh^ Fitz., 

 to which I refer specimens in the Museum from Lado and 

 Monbuttu, and which is probably its nearest ally. C.fasci- 

 atus, its southern representative, is much darker throughout, 

 with a particularly strongly marked black tail-tip. 



Mr. Gillett informs me that, on the day above mentioned, 

 he met about fifteen individuals of this species hunting 

 together in a pack, and that when they saw him several of 

 them sat up on their hind legs and looked at him without 

 fear. The ground tliey were found on was sandy and stony, 

 and covered with thin scrub. Mr. Lort Phillips has also 

 recently seen a large pack of what he believes to be the same 

 species near Berbera.
