S. caffer Pet., and S. tridoctylus Boul. — I suspect that these two 
species will prove to be the same. In the collection of the South African 
Museum there are several specimens belonging to one or other of the two 
species. Two specimens agree entirely in coloration and other characters 
with C. tridoctylus , but one of them has eighteen scales round the body, 
and the other, the larger specimen, has twenty scales. 
Another specimen, exactly similar in the scutellation of the head, 
has twenty scales round the body, and all the scales are dotted with black 
at the base. 
In each case the second finger is the longest, but in the last-mentioned 
specimen it only very slightly exceeds the third finger, and in the two 
former cases it may be stated as second finger slightly exceeding the third. 
These several specimens appear to combine together the ascribed 
characteristic features of the two species. 
S. guentheri Boul. — Of this species I have seen two specimens, one 
from Umfolosi, Zululand, and the other from Natal (Natal Government 
Museum). They differ from the type in the following respects : There is 
no postnasal, the supranasal being in contact with the first labial ; the 
rudimentary hind limbs are devoid of claws, and the colour is laterally 
dark brown, but brown dorsally and ventrally, each scale with a dark 
centre. 
So in respect to the absence of a postnasal, the development of the 
hind limb, and the colour, these specimens approach S. bipes L., but they 
differ in the head scaling and in the snout. On the other hand they agree 
very well with S. ino mat, us but for the hind limb rudiment. According 
to the figures of the British Museum Catalogue inornatus has a pair of 
obliquely elongated temporal scales immediately posterior to each parietal, 
whilst guentheri has three temporals on either side, and they are scarcely 
larger than the ordinary dorsal scales ; but our two specimens of guentheri 
agree with inornatus in this respect also. If this species in question really 
is guentheri— and it was identified as such by Mr. Boulenger in Ann. Natal 
Government Museum, Yol. I, Part 8 — the validity of guentheri is question- 
able, for the only recognizable difference from inornatus is that guentheri 
has a bud-like rudiment of a hind limb, varying in the degree of its 
development, whilst inornatus has no such rudiment. 
The two specimens of guentheri have ninety-eight and one hundred 
ventral scales respectively ; our single example of inornatus has ninety- 
five. 
Herpetosaura anguina Boul. — There is a specimen in the South African 
Museum which is labelled the co-type of this species, and whilst agreeing 
fairly well with the description and figure given in the British Museum 
Catalogue, it differs appreciably in respect to the relative size and shape 
of the interparietal scute ; this scute is longer than the frontal, and is 
acutely pointed posteriorly, whereas the figure given in the British Museum 
Catalogue represents the interparietal as being rather shorter than the 
frontal, and having a curved, almost semicircular, posterior margin. In a 
small series of specimens from Dunbrody (Uitenhage), the same condition 
obtains as in the co-type ; this is also the case with the specimens of the 
Port Elizabeth Museum,
