Specimens of this species are not unfrequent with as few as eighteen preanal
pores; but in the examples which I obtained in Upper Burma, there are twenty-
two in a slightly angular series. The young have occasionally pale yellow transverse
bands on the back, and the tail is broadly banded dark brown and white.
The eggs of this species are strongly compressed ovals, with a long diameter of
O’83 inches and are joined together in a mass of sixteen to twenty eggs.
This is an essentially Malayan form, occurring throughout Burma and the
Andamans, and spreading westwards to the neighbourhood of Calcutta and into
Assam.

I have compared this specimen with the type of P. ca/ntoris, Giinther, from
Penang, with which it agrees, except in that it has twenty-four femoral pores,
continued across the preanal region as in H. (Peripia) mutilatus. The tail is imperfect,
but what remains of it has no enlarged sub-caudals.
I obtained only one example of this rare Gecko at Ponsee, at an elevation of
3,300 feet on the Kakhyen Hills..

This is a common Tree- Gecko at Bhamó, where in the months of February and
March I found it on trees ; but it occurs also in the houses which are all built of
bamboo and teak.
Young specimens are brown, marked with small blackish-brown spots, and with
smaller interspersed whitish spots. The adults are pale olive greyish-brown, with
hardly any trace of spots, but all the scales of the upper surface, as in the young,
are minutely punctulated with brownish. The colour of this lizard tends to
conform to the surface on which it lives, while at the same time the young are
more deeply coloured than the adult. I have compared these specimens with
examples of the species in the. British Museum, both from the Isle of France and
Ceylon, with which they structurally agree. They have all the enlarged chin shields,
and the preanal pores vary from thirty-six to thirty-eight in these individuals, but
Theobald has observed as many as forty-two in Rangoon specimens.
The edge of the tail is minutely serrated in all, depressed and rather flattened
on the under surface, with a mesial line of enlarged sub-caudals raised above the
level of the small imbricate scales external to it, and which are arranged in oblique
rows numbering about six scales to each row, on either side, at the base of the tali.
The numbers of these scales diminish from before backwards, so that at the middle
of the tail, and throughout the rest of its extent, they become reduced to two or three
in each row, the under surface of the tail being thus, in its distal half, wholly occupied
by the enlarged sub-caudals. In its latter half, the tail tapers rather rapidly to a
