ON CHBYSOCHLOBIS NAMAQUENSIS, Broom.

(Read March 16, 1910.) 
When in Namaqualand thirteen years ago I made at Garies a collec- 
tion of the skulls of small mammals from the disgorged pellets of owls. 
Among them I believed I had discovered the skulls of three new species 
of Ghrysochloris, which in the Annals and Magazine of Natural History 
for February, 1907, I named as C. granti, C. namaquensis , and C. tenuis. 
A fuller description was afterwards published in the Transactions of the 
South African Philosophical Society, vol. xviii., pt. 3. Of G. granti I was 
fortunate in discovering a skin in the South African Museum. Besides 
being the smallest known species it difiers from all others in having long 
fur and in having the 4th claw of the front foot well developed. C. nama- 
quensis and G. tenuis agreed with each other pretty closely, except that the 
former has 40 teeth and the latter only 36. As only the skulls were 
known, I have been endeavouring for some time to get skins, and have 
at last been successful. 
From Mrs. Thomas Dixon, of Roodeberg Kloof, near Garies, I have 
obtained a spirit specimen of a young female of G. namaquensis. Though 
badly preserved, owing to the spirit having been too weak, it is possible 
now to give a complete description of both the skin and the skull. 
The nose- pad measures 9*5 mm. in width and resembles that of G. 
asiatica in having the outer corners pointed. 
The fur over the back is light brownish grey, the deeper fur being pale 
slate. On the abdomen and breast the terminal parts of the hairs are 
much lighter. Round the lips and down the chin the hairs are short and 
of a pale creamy-yellow colour. On the cheeks and top of the head the 
yellow hairs are continued, but over the forehead, the nasal region, and 
especially behind the outer angles of the nose-pad, the hairs are tipped 
with brown, so that there is little difference in colour between the frontal 
region and the dorsal, except that the former has a yellow under-fur and
