other two are also young is not evident, though probable. The specimen 
from Kastrol Nek is dark coloured, of about the same shade as the majority 
of $$ taken at Wakkerstroom. The skulls of these three specimens

67. Amblysomus hottentottus albirostris, Wagn. 
13, Port St. Johns (Swinny and r-hortridge). 
It is clear from a study of this series of skins that the young are 
altogether darker coloured on the back than adults, and the sides of the 
face are also whiter, in the young stage being typical of Wagner’s 
albirostris • the series clearly shows the transition from albirostris to 
Thomas and Schwann’s A. h. pondoliae, which must therefore revert to the 
synonymy of the former. 
The skulls measure in greatest length, ^ 27, $ under 26 mm. 
68. Amblysomus corriae , Thos. and Schw. 
1 <J, $, and 1 in spirits, Knysna (Rex and Grant). 
In colour this species is so distinct from hottentottus that, despite the 
similarity in general of its cranial characters, I think it is advisable to 
retain it as a distinct species. There are also two more specimens without 
labels, apparently from the same place. 
69. Amblysomus corriae septentrionalis, subspec. nov. 
This subspecies is founded on a single gravid $ taken at Wak- 
kerstroom on 14th September, 1909, in precisely similar conditions as 
A. h. longiceps. In colour it much resembles the specimens of corriae 
known to have been collected at Knysna, though more like the two 
without labels ; it differs also in having a very conspicuous yellowish 
patch at the sides of the snout. The skull is very much larger, having 
regard to its sex, than in any member of the subgenus so far recorded. 
At the time this specimen was taken I was collecting gravid 5$ 
for the purpose of preserving the embryos ; but, although about sixty 
specimens of the common species ( A . h. longiceps) were captured, this was 
the only one taken of the black species. I have since made special efforts 
to get more, and, although I have on several occasions been told of its 
having been captured by farmers and Kaffirs, have not so far met with 
success. The single specimen taken was dug out when it was throwing up 
a mound, and showed extraordinary activity in trying to escape. 
The following are measurements of the skulls of four specimens of 
this species 
mentioned above and of the one from Wakkerstroom : —
