hairs of the upper surface with only their extreme tips brown (' wood 

 brown ' in a specimen skinned out of spirit), the greater part of 

 their length being silvery whitish (with a tinge of yellow in the 

 type, but this is probably due to the spirit) very slightly greyer at 

 their bases. The brown is, as usual, most intense on the crown, 

 where it contrasts with the cheeks, which are yellowish white. 

 Under surface yellowish white, the hairs light to their bases, line 

 of demarcation on sides not defined. A slight greenish iridescence 

 on the dorsal hairs." 



The following are the principal measurements of the skulls of the 

 four specimens I have seen with those of Peters' type and those of 

 Thomas and Schwann's type of C. chrysilla : —

From a comparison of these measurements it is pretty manifest 

 that the four specimens I have examined belong to the same species 

 as A. chrysillus of Thomas and Schwann, and the question is 

 whether all these are different from Peters' G, obtusirostris. The 

 only points which are given as distinguishing A. chrysillus from 

 G. obtusirostris are the smaller size and the lighter fur. The 

 specimens examined by Thomas and Schwann have been spirit 

 specimens, and it is undoubted that spirit makes the fur lighter. 

 Two of the Zululand specimens which have not been in spirit are 

 quite as dark as Peters' type, and we are thus left with only a slight 

 difference in size to distinguish between the forms. As the skulls 

 of G. asiatica vary in length from 21 to 24 mm., and those of 

 G. hottentota from 23 to 30 mm., the difference between 22 and 

 24 mm. does not seem to me to be greater than the probable 

 variation of the species. I therefore feel inclined to regard the 

 Delagoa Bay and Zululand specimens as at most only a sub-species 

 of Peters' G. obtusirostris. 



Cheysochloris villosa, Smith. 



This large Natal mole does not seem to be very well known. 

 Dobson had only seen one specimen, in addition to Smith's type, 

 and seems a little in doubt as to whether his specimen may not be
