This species has not been recorded from the Empire of 

 India or Ceylon^ but probably it occurs in Teuasserim. It 

 is by no means rare in the hill-jungles of the northern part 

 of the Malay Peninsula south of the isthmus of Kra ; and 

 the greater number of the geckos known from this district 

 have already been recorded from Lower Burma also. 

 Stoliczka's type, from Pcnang, is in the Indian Museum ; it 

 is in bad condition. 



Gonatudes uffinis is the only gecko which is known to enter 

 water. Laidlaw has taken it on rocks in a jungle-stream, 

 and I have frequently observed it slip beneath the surface of 

 water collected in hollows in a tree-trunk and remain sub- 

 merged for some minutes. When in water the skin of the 

 back has a silvery appearance^ owing to the retention of a 

 film of air by the enlarged tubercles. Formerly I regarded 

 this as fortuitous; but an examination of the tubercles 

 has made me doubt whether I was right. As Boulenger has 

 noted, they are not merely keeled, but also grooved. Possibly 

 this peculiarity in their structure may assist in the retention 

 of the air-film. The air so retained could not be used in 

 respiration, but it might well protect the organism from a 

 too rapid lowering of temperature, for water in a shady place 

 in the Malayan jungle may be cold.

A specimen of this interesting form has lately been pre- 

 sented to the Indian INIuseum by H. W. Biggie, P^sq. It is 

 from Pitsanuloke in Northern Siam. An adult male, it has 

 7 pra^anal pores, arranged in a curved line and not interrupted 

 mesially. Its size is considerably greater than that of the 

 type. The following are its dimensions : —
