no canthal ridges, in having a median row of enlarged and 

 pointed but not erect scales beneath the tail, in the male having 

 a series of from 2 to 8 preanal pores, which may, however, be 

 absent altogether, and in the much smaller size — head and body 

 42, tail 58 mm. Type, author's number 2337 collected at 

 Maprit, near Patiyu. Peninsular Siam in 1916. Colour brown- 

 ish-green, finely mottled with lighter and darker shades. 



I have also examined specimens of this new Gecko from 

 Puket, Krabi and Tasan in Peninsular Siam, from Pak Chan 

 in southern Tenasserim, and from Khao Sebab. near Chan- 

 tabun in S. E. Siam. The type has been presented to the 

 British Museum of Natural History.
