196. Georyclius , spec. ? 
1 juv., Knysna (Rex, ex Daneel). 
This specimen is similar to the young of G. hottentottus from the 
same place, as regards size ; but it is altogether paler in colour and has a 
small white blaze on the forehead. This must, I think, belong to a 
distinct species allied to G. Darlingi. I also captured a similarly marked 
specimen in the Dargle district, but it is unfortunately not now in the 
collection ; it was taken in the burrow of Chrysnchlons , a specimen of 
which it had severely mauled in the same trap the day before. 
197. Georyclius Darlingi , Thos. 
1 <£, Salisbury (Marshall). 
Thanks to the kindness of Mr. Hewitt, curator of the Albauy Museum, 
I have been able to examine the specimens of G. Darlingi from Grahams- 
town mentioned by Sclater in his “ Fauna of South Africa.” They are 
not referable to Darlingi; but another undescribed species allied to it. A 
curious feature of these specimens is that only the <$<$ Rave a white frontal 
mark, the $$, which are slightly smaller, lacking it. Under the circum- 
stances I have thought it advisable not to apply a name, as it is possible 
that the type of one of the three species now relegated to the synonymy 
of hottentottus may have been a $ of this species. In these specimens the 
premaxilla usually closes up behind the nasals, as in Darlingi , but on the 
whole they are smaller and offer slight differences in other respects. 
198. Georyclius amatus , Wr. 
1 <3\ Katanga (Neave). 
199. Georyclius Bocagei , De Wint. 
1 juv. (£, Angola (Ansorge). 
200. Georychus hottentottus , (Less.). (Text fig. 6.) 
16, Knysna (Rex). 
The nasals in old specimens are blunt at the hinder end, near which 
is the broadest part, then taper forwards to the tips in straight lateral 
lines : they measure 3 * 5 mm. across at the back and 2 mm. at the tip. There 
are six very old specimens in the series which are so very much larger 
than the rest that it is 'possible they may belong to a larger species; but 
from a study of several large series of skins takeiufrom the same burrows 
in places in other parts of South Africa, it would seem that the full 
dentition is often obtained at a young age, as the following table will 
illustrate : —
