CIIELONIA.

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 tlie 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 witli 

 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. 



2. Chelone imbricata, Linn.

(1907). 



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. 



LACERTILIA. 



3. Hemidactylus frenatus, D. and B. 



Mocquard, Les Reptiles de I'lndo-Chine, p. 29 (1907). 

 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.
