collecting live turtle and tortoise-shell, the former of which 
are sold in Singapore while the latter finds a market in Rhio. 
They possess small kampongs where bananas, maize, ubi kayu 
and sugar cane are cultivated, but no rice is grown. 
_ We stopped a couple of days on the Eastern side but 
being warned than the anchorage there was precarious in bad 
weather were conducted by a very tortuous and intricate 
channel to a little pool (it was hardly more) on the western 
side near an islet known as Mentigi, a commonplace name 
among orang laut people, where we remained a week. 
The collecting was disappointing but besides the species 
actually secured we caught a fleeting glimpse of a Tvagulus, 
while pig of both species, Sus of and Sus rhionis are known 
to occur, but without dogs are difficult to obtain. In the 
sheltered bays in the vicinity Duyong (Halicore duyong) are 
very fairly common and are much hunted, cigarette holders 
made out of the canines being much prized and commanding 
a high price in Tanjong Pinang (the capital of Rhio). On 
‘our way back to Singapore we shot a small dark brown 
porpoise, one of a school? (Flatanista sp.) of fifteen or twenty, 
but it was seized by a shark and torn to pieces before we 
could secure it. 
Of reptiles we got hardly any: Cyclemys platynotus is 
fairly common and so are Draco volans, D. melanopogon and 
Mabma multifasciata, while we also secured specimens of 
the Hawks bill turtle. Near Mentigi was a pen in which 
were some fifty or sixty green turtle (Chelone mydas) which 
were bought up by a Chinaman for sale in Singapore and 
fed ona variety of sea-grass common in shallow bays in the 
neighbourhood.
