25 specimens from the Great Karas Mountains, and from Quibis. 
They were all found in the crevices of rocks. 
The form laevigatus was taken at Kraikluft (elevation 5200 feet), at 
Narudas Slid, and between Kraikluft and Alt Wasserfall. The keeled 
forms (three specimens) were taken at Narudas Slid in precisely the same 
localities as laevigatus. These keeled forms appear to agree with 
Werner’s variety stellatus but we do not think the form can be maintained 
as of varietal importance since it merges completely into bibroni proper. 
P. montanus , sp. nov. 
A single example from Lord Hill’s Peak in the Great Karas 
Mountains, at an altitude of 7300 feet. Type, T. M. Cat. Rept. No. 3080 
in the Transvaal Museum. 
Related to P. iveberi, Roux (Zool. Jahrb. 25, 1907, p. 408, Taf. 14, 
Fig. 4, 5) : the differences therefrom are mentioned later. 
Description : head rather large : head and body depressed. Snout 
one and. a half times as long as the diameter of the orbit. Ear-opening 
elliptic nearly vertically oblique. Third toe bears interiorly seven 
lamellae. Rostral, which is about twice as broad as deep, enters the 
nostril. The latter is pierced between two postnasals, naso-rostral, first 
labial, and rostral. Naso-rostrals in contact. The first labial is not 
pentagonal as described for P. iveberi , but normal, i.e. four-sided. The 
symphysial is practically as deep as the adjoining labials, not as broad : it 
is a little more than twice as deep as broad. Labials f on the one, on 
the other side. 
The dorsal lepidosis is heterogeneous. The granules on the snout are 
enlarged and are twice or a little more than twice as large as the granules 
on the back. On the back mixed with the small granules are tubercles of 
moderate size somewhat flattened but keeled : these tubercles are quite 
separate from one another and arranged more or less in longitudinal lines: 
on the flanks however they are close together, less regularly arranged and 
less flattened. The tubercles on the back lose themselves gradually on 
the back of the head and behind the eyes. Further, there is a narrow 
mid-dorsal area on the back free of tubercles. Below, the scales are 
sub-imbricate, those in middle of belly slightly larger than those on the 
sides thereof. 
The scutellation of the tail differs from that of P. iveberi. The tail 
is the original one, the tip only (8 mm.) having been regenerated. It is 
divided into a number of segments, each segment carrying dorsally four 
to five transverse rows of scales : marking each segment is a single row of 
flattened moderately keeled tubercles. 
Colour and markings in life : behind the head a dark horse-shoe 
band, and across the back a number of dark ferruginous broken bands, 
some forming large ocelli, others in the form of vermiculatioHS : tail with 
broken cross-bars. Rest of upper surface purplish grey inclining on 
flanks and between eyes to olive : a lighter streak behind the upper lip 
and over the ear : the lips still lighter. A light yellowish streak from the 
anterior border of the eye to the snout. Anterior and posterior borders
