This peculiarity is very pronounced and is quite distinct in a young adult

207. Georychus , spec. ? 
In dealing with the Rudd collection of small mammals, Thomas and 
Schwann placed Knysna specimens of the grey mole as G . hottentottus, 
and I have therefore done likewise. The question of whether the names 
of G. hottentottus , caecutiens , and ludwigi are synonymous is still open to 
doubt, however, and it is not until a very careful research into the life 
history of the species found in different parts of the Cape Province has 
been studied that we shall be able to prove their validity. The shape of 
the nasals and the general colouring is like that of the specimens placed 
with G. Darlingi by Sclater, but the white blaze on the forehead is absent 
in the 
The present species is smaller than any of the grey species described 
above, and in addition has a rich suffusion of sandy buff over the whole 
of the body. It is not a stain due to the colour of the soil, as in the case 
of some of the specimens of G. arenarius, but a fixed character found in 
specimens taken in widely separated localities. 
This smaller, richer-coloured, species, is represented in the collection 
by specimens from Pirie Forest (old $, Stenning), Malvern, Natal (old
