This specimen, the only one obtained, is not fully adult. 22:p0- 
dillus harwoodi was described by THomas from a specimen 
collected by Mr. L. C. HarwooD near Lake Naïivasha. Quite 
recentlv there has been added to the British Museum Collection 
a specimen of this diminutive Gerbil from the Southern Guaso 
Nviro, so the species is probably widely distributed over the 
Southern parts of British East Africa. 
12. — Tatera nigricauda PEr. 
©. 89. Tsavo. 
This specimen exhibits to advantage the black-haired tail so 
characteristic of this Gerbil. It would appear to be found over 
most of the Southern parts of British East Africa; in the North, 
along the Northern Guaso Nviro, it is replaced by 7° nigricauda 
uyama, a paler form, but still possessing a dark coloured tail.
