rounded ; they are arranged, as a rule, in 16 to 20 alternating, longitudinal, 
but not very regular rows ; they are slightly larger and sharper in adult males 
than in females. The enlarged scales on the middle of the belly somewhat 
extend to the sides and are usually in 38 or 40 longitudinal series. The 
femoral pores in the male are 10-14 on either side, very rarely united 
in the preanal region ; as a rule, they are separated by 1 or 3 or 5 scales ; 
if 3 intermediate scales are present, which is very often the case, they are 
arranged in a triangle. 
The specimen recorded by Theobald in Cat. Kept. Asiat. Soc., p. 30, 
under the name “ H.fasciatus, Gray (?)” is II. maculatus ; the former having 
been described from an unknown locality must, therefore, provisionally remain 
under that doubtful head, and not be added to the Indian fauna. 
The four specimens in the Museum from Ceylon, recorded by Theobald 
in Cat. Eept. Asiat. Soc. p. 30, No. 41, as II. maculatus, belong to the larger 
form; two of them have the body about 3-J- inches and in one the tail is 
3f, giving a total measurement of nearly 7 inches. In structure of scales, 
tubercles and shields, the specimens do not exhibit any important difference 
from maculatus, as usually understood, though at the first sight they 
appear quite distinct. The two other specimens equal in size typical 
maculatus, but when closely compared with specimens of this species, 
they evidently possess a certain, aspect of immaturity and tenderness 
of the skin, &c. ; their heads are proportionately larger, and the same 
is the case with the trihedral tubercles, which are present in a slightly 
smaller number (14-16 rows) ; their colour is almost uniform whitish. 
In the two adults, the differences are still more marked, and the 
brown marbling has an inclination to form transversely arranged bands, 
very similar to a spechnen described by Gunther under the name of IT. 
Sylcesi.* The number of femoral pores is 32-36, in a slightly interrupted 
series. For this Ceylonese form, Kelaart proposed the name II. Pieresi 
(Prod. Faunae Ceyl. 1852, p. 159), and as far as can be seen from the 
drawing of H. Sykesi (in Gunther’s Reptiles), the latter does not in any 
way differ from the former, therefore, Kelaart s older name must take 
priority. It also seems to me clear that Dam. and Bibron s largest specimen 
of maculatus, of which they give measurements, is the Sykesi of Gunther ; 
it is said to occur in the neighbourhood of Bombay, wherefrom Dum. and 
Bibron received it. Dr. Gray is evidently the original observer of the two forms, 
the small maculatus and the large Pieresi, as shewn by him in his ‘ Lizards’ 
p. 153, where he gives “ II. Sykesi, Gray, B. M.” as the synonym of 
maculatus ; and among the specimens of that species he quotes “ a. In 
spirits. Female ? India, Dukun. Presented by Col. Sykes.” This is to all 
appearance the only type of Gunther’s species, bearing the name II. Sykesi.
