For localities, the names of the British Admiralty Chart (2721) 
have been followed, except that instead of “Ile du Pic”, “ Le 
Chameau” and “ Koh Loi” I have used respectively Koh Mehsi Yai, 
Koh Mehsi Lek and Koh Rang—names current locally. Klong 
Menao, unmarked, is about 15 miles north of Klong Yai.—C.B.K. ]

Three adult and two young individuals from Koh Chang. 
The carapace of the largest example measures 220 by 158 mm. 
In the young animals the tail is relatively of much greater length than 
in the adult and is actually nearly as long as in the latter. The 
species was apparently common on Koh Chang and was obtained from 
the rocky stream above which the camp was placed, but was met with 
nowhere else during the excursion. It has been found also upon 
the mainland at Hup Bon, E. of Sriracha, where it appears to be 
fairly common. It is an active and voracious creature, devouring 
greedily animal as well as vegetable food. Its habits are chiefly 
aquatic.

One example was obtained at Koh Chang and another observed 
at Koh Mak. The Hawksbill Turtle is not uncommon in the Gulf of 
Siam. The shields of the head and limbs in the specimen obtained, 
were black instead of dark brown.

At Klong Yai this species was caught in numbers by the 
village children, but not so extensively as the next. One specimen is 
entirely without tubercles on the tail owing to reproduction of that 
part.
