LACERTILIA. 



Fam. GECKONIDAE. 



3. Gymnodactylus khasiensis (Jerdon), 



Bouleiiger, Fauna, p. 68. 



Originally described frora the Khasi Hills, this lizard appears 

 to have a fairly wide range in the mountains of Assam and north- 

 ern Burma. 



Two specimens were taken by Mr. Kemp at Kobo in Decem- 

 ber under the bark of a tree, together with a young Ptyctolaemus 

 gularis. Others were obtained by the 32nd Sikh Pioneers at an 

 altitude of about 2,000 feet at Upper Rotung. 



My own G. himalayicus ' is a very closel}^ related species, 

 differing in its slighter build, more obscure colouration and less 

 compressed digits and also in having a well-defined triangular 

 patch of enlarged scales just behind the praeanal pores. This last 

 point, however, is not a very good character as in some specimens 

 of G. khasiensis, of which I have examined a large series, there is 

 a single enlarged scale, or even a pair of such scales, in the same 

 position, although in others the scales are uniformly small. 



4. Hemidactylus frenatus, D & B. 



A very common lizard at low altitudes in the E. Himalayas, 

 Assam, Burma and the Malay Peninsula; often found in houses. 



A specimen was taken on a lamp-post in the streets of Dibru- 

 garh in November. 



5. Hemidactylus bowringii (Gray). 



Not uncommon at low altitudes in the E. Himalayas and in 

 Assam and Burma, this species is occasionally found in houses. 

 It is, however, more often taken in the jungle. 



There is a specimen in the collection from Sadiya. 



6. Hemidactylus brookii, Gray. 



Hemidactylus glcadovii, Boulenger, Fauna, p. 86, fig 27. 

 Hemidactylus brookii, id., Ann. Mag. Nat. Hist., (7) i, p, 123 

 (1898), and Annandale, Rec. Ind. Mus., vii, p. 45 (1912). 



This species, which is one of the commonest house-lizards all 

 over the plains of India {in northern Madras certainly the com- 

 monest), has a ver}^ wide distribution in the tropics but apparentl}^ 

 avoids mountainous regions. The highest altitude from which I 

 have seen a specimen is 4,500 ft., and this was on the isolated 

 mountain Paresnath in Chota Nagpur, now in the new Province of 

 Bihar and Orissa. Several specimens were obtained at Sadiya.
