and the species which is abundant above Bendang Stah is very probably 
C. palustris ; it occurs on the islands of the Taleh Sap and in the Lampam 
River, for a Siamese crocodile hunter at Lampam showed me a number of skulls, 
all of which appeared to be those of C. porosus. He told me, however, that 
about one individual in every hundred he killed had a very long nose, with a 
lump at the end, that is to say, probably, was a specimen of Tomistoma horneenis.

14. Gym nodactyl us marmoratus, Kuhl. 
Bukit Besar. 2,500 feet. 
‘ Not uncommon on tree-trunks in the jungle. When disturbed it 
frequently runs down to the ground, and takes refuge in one of the rats’ holes 
common at the roots of trees.’ 
15. Gymnodactylus pulchellus, Gray 
Bukit Besar, 2,500 feet, and Goah Tanah (Earth Cave), near Biserat. 
‘ The specimen from Bukit Besar was obtained from a hole in the trunk 
of a dying palm, about thirty feet above the ground. Those from the Jalor 
cave were found crawling on the sides and floor in absolute darkness ; there 
are specimens, taken in a similar habitat in Selangor, both in the State Museum 
at Kuala Lumpur and in the Raffles Museum at Singapore.’ 
16. Gonatodes aflinis, Stol. 
Bukit Besar. 2,500 feet. 
‘ Dorsal surface dull grey, mottled with black and closely banded with 
yellow ; mid-dorsal line slightly paler yellow ; a large black spot, with a bright 
yellow “ eye ” in the centre, and bordered posteriorly with the same shade, just 
behind the base of the fore limbs, these markings being far more conspicuous 
in the male than in the female ; three faint yellowish lateral bars.’ 
‘ Common on tree-trunks in the jungle, especially on the one on which 
the frog Ixalus horridus was taken. The gecko was generally found between 
the upper part of the buttresses of this tree, but when it was disturbed it 
slipped down into the water in the cavities, beneath the surface of which it 
remained for some minutes, finally pushing out its head at one side so carefully 
that not the slightest commotion was caused. The roughness of its integument 
caused it to be covered with a film of air while beneath the surface of the
