DR. MALCOLM SMITH ON 



Iii addition to the specimens here enumerated, two others 

 only appear to be recorded from the Asiatic mainland, one from 

 Ginting Bidai, and a second from Gunong Tahan in the Malay 

 Peninsula. In all the specimens (example from Ginting Bidai not 

 examined) the praefrontals form a broad suture. 



The mainland form therefore appears to differ from the 

 typical (archipelagic) one in the following particulars : — longer pro- 

 portion of body, the distance from the snout to the fore-limb being 

 once and one-sixth to once and one-third in distance from axil to 

 groin, shorter limbs, praefrontals always in suture, and greater 

 average number of scales round the body.
