The Box-Tortoise is the chelonian most frequently met with in the Straits Settlements, and seems generally distributed in the low country, living in ponds, streams, and paddy-fields. I have seen specimens from Alor Star in Kedah, from Penang, from Taiping in Perak, from Malacca, and from Singapore. There are a score or more living in the Ayer Etam Tortoise Temple. I did not meet this species myself in Siam proper, but the British Museum Catalogue mentions a specimen from Siam. Habits. When first caught they are very shy; for some weeks on being touched they will at once shut themselves up in their shells, but they gradually get used to people being about them. They feed fairly regularly on vegetables, preferring bananas, but only eat small quantities at a time (a great contrast to the greedy C. platynota). Size.

The Spinous Tortoise is found in jungle-streams apparently only in the hills, in Penang and Perak at elevations of some thousand feet above the sea, but in Singapore it is found on Bukit Timah at less than 500 feet. It is one of the mountain forms which are thus found at a low elevation in Singapore, as if Bukit Timah had once equalled the more northern granite hills in height, and when it gi\adually sank by subsidence or denudation the animals and plants on it had to accommodate themselves to this lower level. I find that Cantor noticed this, having written in 1847 of Singapore :-" In the valleys occur vegetable and animal forms which at Pinang have been observed at or near the summit of the hills, but not in the plains. Thus, at Singapore occur Also- |
