Iguanidae. 
Hoplurus cyclurus, Merrem. From the south-west; records from 
Tulear and district and the Onilahy River as far as Tongobory. 4122-26, 
4253, 4254. 
H. quadrimaculatus, A. Dum. Two specimens were taken at 
Ambohibola, in the hills near Tulear. One of these is evidently juvenile. 
The head-scaling in the two differs considerably. The larger example, 
which measures 373 mm., of which the tail is 260 mm., has the scales between 
the nostrils strongly keeled ; so also those covering the fronto-nasals. 
The scales between and behind the supra- orbitals and covering the parietal 
bones are convex, some being conical, and others keeled but not so strongly 
as those between the nostrils. The supra-orbital scales, on the other hand, 
are almost flat. The “ occipital ” shield is only slightly larger than the 
surrounding scales. The anterior border of the ear has about twelve 
spine-like scales of varying size. 
In the case of the juvenile specimen, the head scales, excepting a 
few between the nostrils, are almost smooth, and the “ occipital ” shield 
is considerably enlarged. 4117-18. 
H. saxicola, Grandid. Found living among rocks near Miary, district 
of Betsioky. It is worth mentioning that the shape of the “ occipital ” 
scute in our specimens varies considerably. 4119-21. 
Chalarodon madagascariensis, Peters. A common lizard in the 
south-west, especially in sandy parts. Taken in the district of Tulear, at 
Tsivanoa. 4141-45, 4262-63. 
GeRRHOSAURIDAE. 
Zonosaurus ornatus, Gray. Two specimens from the eastern 
forest of the mountainous districts adjacent to Analamazotra and Ambo- 
hidratrimo. One of these, which is juvenile, possesses three upper labials 
on one side and four on the other, anterior to the sub ocular shield ; the 
frontal is elongated and the prefrontals form a short suture ; it has fifteen 
femoral pores on each side. The adult specimen, which has twelve femoral 
pores on each side, measures 300 mm., of which the tail is 185 mm. 4140, 
4261. 
Z. madagascariensis, Gray. Two specimens from the neighbourhood 
of Tongobory in the south-west. In one individual the prefrontals form 
a median suture of some length ; in the other these scales are well separated. 
The length of the fronto-nasal relative to that of the frontal varies accord- 
ingly in the two. The interparietal is absent in one, barely suggested in 
the other specimen. The femoral pores on each side number twenty-four 
in one, twenty-three in the other. The length of the largest specimen is 
382 mm., of which the tail is 242 mm. 4138-39. 
Tracheloptychus madagascariensis, Pet. Several specimens from 
the south-west, along the Onilahy River. 4129-30, 133-34, 4258. 
T. petersi, Grandid. Several specimens from sivanoa. 4127-28, 
4131-32, 4135-37, 4259,-60. 
SCINCIDAE. 
Mabuia aureopunctata, Grandid. On the Oniiahy River, several 
individuals. In ev-ery case the prefrontals form a fairly long median
