22. Gecko stcntor, Cant, 
Batang Padang. 
‘Though somewhat scarce in collections, this gecko is really common in 
the Malay jungle, especially in Upper Perak and the adjacent parts of R ham an, 
where I heard its characteristic cry almost continuously. It is usually a jungle 
species, frequenting the upper branches of high trees, but a large specimen, 
now in the State Museum at Taiping, Perak, was taken in a hospital (built at 
the edge of the jungle), in the walls of which its cry had disturbed the patients 
for some time. Our specimens were shot on trees by the Sakais, with their 
blow-guns ; they consider its flesh a delicacy. The changes of colour under¬ 
gone by the individuals of this species are very slight, being confined to a 
slight paling or darkening. 
* The characteristic note of this large gecko is often heard in certain 
bungalows in Kuala Lumpur/ H.C.R,

Bidor, South Perak ; Kuala Lumpur, Selangor. 
* The species appears to be somewhat particular as to its environment, 
occurring abundantly on the walls and ceilings of some houses, but avoiding 
others close to them. It has very little power of colour change/

24. Ptychozoon homalocephatum, Gray 
Two newly hatched young, from eggs obtained on Bukit Besar. 
* The eggs, of which several sets, hatched and otherwise, were noted on 
Bukit Besar, are deposited in pairs, on the lower surface of leaves or on tree- 
trunks, sometimes quite near the ground. They have brittle calcareous shells, 
but must be soft when laid, as they are flattened where they come in contact 
with one another, the outline of the two together forming a figure of eight, and 
as the lower surface, which is also flattened, retains an impression of the 
surface to which it clings and on which the eggs have been laid. The eggs measure 
about 13 mm, in diameter, and 11 mm. in depth. The period of incubation 
is long for so small an animal ; in the case of the eggs of a captive specimen
