284 Transactions of the South African Philosojjhical Society. 



1907, I have given a preliminary description of five new species. In 

 the present paper a sixth new species is described and two new 

 varieties are named. It seems probable that one or two new species 

 remain to be discovered, but in the meantime it seems advisable to 

 review the present state of our knowledge of the genus. 



Chrysochloeis asiatica, Linn. 



This, the earliest known species, is the one which is found in the 

 neighbourhood of Capetown. Its burrows are to be met with almost 

 anywhere in the low ground of the Cape peninsula. From here it 

 extends all over the Cape flats and for a considerable distance east- 

 wards. At Stellenbosch it is fairly common. It certainly occurs at 

 Ceres, but it does not occur as far north as Namaqualand. An old 

 specimen in the South African Museum is said to have come from 

 Kimberley, but as there is no other record of its occurrence north- 

 east of Ceres, and at Beaufort West another very different species is 

 met with, I am inclined to doubt the record. Along the south coast 

 the farthest east records are Bredasdorp and Swellendam. 



There is considerable difference in the colour of different speci- 

 mens. Those from Stellenbosch are usually slaty-grey to black, 

 rarely with a slight brownish tinge. In the region of the eye there is 

 a white spot, which frequently extends downwards and joins its 

 neighbour round the upper lip. Occasionally the white spot is small 

 and rounded, and at a little distance looks like an eye. In some 

 specimens a white triangular patch is situated above the snout, but 

 no two specimens quite agree. Some specimens from the Cape 

 peninsula are very distinctly brownish, occasionally even rather 

 light brown. In the Cape specimens the cheek light spot is larger 

 than in those from Stellenbosch. By no stretch of imagination 

 could Stellenbosch specimens be called " golden," but some of the 

 Capetown specimens have the rich golden-brown colour seen in some 

 specimens of 0. ohtusirostris. 



Adult specimens of both male and female measure from 110 to 

 115 mm., and the hind foot 12 mm.

The skull is characterised by its great relative breadth and by the 

 large size of the bony projection in the back of the temporal region.
