decide, whether this Varanus is a very old specimen of any of the species mentioned, 

 or not, as material for comparison is lacking. It is for instance possible that very 

 old specimens of V. nebulosus get their abdominal scales keeled when they have 

 attained a great age. That the present specimen really must be regarded as old 

 appears to be proved not only by its size, but also by the thickness of the integu- 

 ment, especially the very thick scales of the upper neck, which form a protective 

 armour. The stoutness of the powerful claws etc. speak for the same thing. 



16. Varanus salvator Laur. 



A very large specimen (skin and skull) measuring about 250 cm. in total length. 

 This specimen was shot in a swamp at Tha Law, Central Siarn. 



»This species is rather common in Central Siarn in the great swamps. » 



17. Tachydromus sexlineatus Daud. 



1 specimen from Ban Sakerat, Siarn 1912. 



When Stanley S. Flower in the year 1899 wrote about the Reptiles of Siam 

 he expressed the belief that this species probably would be found in Siam as it is 

 irecorded from both Burma and Cochinchina». This has now proved correct. 



18. Mabuia multifasciata Kuhl. 

 3 specimens from Ban Sakerat, Eastern Siam, Jan. 1912. 



19. Mabuia siamensis Gthr. 



1 specimen from Keng Soi at the middle course of Meping river, Northern Siam, 

 7io 1914. 



20. Lygosoma maculatum Blyth. 



1 specimen from Pak Koh, Northern Siam, March 1914; 1 specimen from Bång 

 Hne Pong B - 1914; 3 specimens from Doi Par Sakeng 16 /? 1914. 



21. Lygosoma olivaceum Gray. 

 1 specimen, Siam, 1914 (M. Smith coll.).
