CROCODILES, TURTLES, AND TORTOISES 113 



at Sintang, Borneo, and the identity of the adult 

 remained in great doubt. It was described in the 

 Sarawak Gazette by my predecessor, Mr. E. Bartlett, 

 as Brookeia baileyi, by Baur as Adelochelys crassa, and 

 again by Mr. G. A. Boulenger as Lieinys inornata. 

 Finally, by the study of young specimens sent by me, 

 and an adult by Dr. C. Hose, Mr. Boulenger was for- 

 tunately able to establish the identity of the small 

 British Museum specimen with the adult, and Gray's 

 specific name, borneensis, therefore stands. This Tor- 

 toise lays long, oval eggs with a shell of porcelain-like 

 texture ; in fact, they are like little Crocodile eggs. It 

 may be noted here that whilst the eggs of Turtles have 

 leathery shells like those of Snakes, those of Tortoises 

 have hard shells like Crocodile's eggs. Mud- Turtles of 

 the genus Trionyx* were common enough in Sarawak, 

 but I have nothing fresh to record about their habits. 

 They are vicious creatures, capable of inflicting bad 

 wounds with their powerful jaws. 



1 A figure of Trionyx subplanus is given by S. S. Flower in P.Z.S., 

 1899, PI. XXXVI, opposite p. 600. They live chiefly in holes along 

 the banks of small rivers, and lay a small round egg with a hard 

 shell. They kill waterfowl. C. H.
