collecting live turtle and tortoise-shell, the former of which 

 are sold in Singapore while the latter finds a market in Rhio. 

 Thej' possess small kampongs where bananas, maize, ubi kayu 

 and sugar cane ate 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 Tragulus, 

 while pig of both species, Sits oi and Sits 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 1 . 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 platynoius is 

 fairly common and so are Draco volans, D. mclanopogon and 

 Mabuia 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 (Ghelone mydas) which 

 were bought up by a Chinaman for sale in Singapore and 

 fed on a variety of sea-grass common in shallow bays in the 

 neighbourhood.
