164 Indian and Malayan Amphibia and Peptilia. [No. 3, 



P. Peronii is also recorded by Mr. Theobald from Burma. 

 The name Gecko pardus (Journ. A. &., B. xxxiii, 1864, p. 547) 

 appears to have been applied to it by Col. T y 1 1 e r. 



The largest specimen of P. Peronii collected was six inches. In 

 some specimens, I find the posterior plates on the toes are only 

 angularly bent and not perfectly divided, what clearly indicates 

 that the distinction between Gecko and Peripia is only of subordi- 

 nate importance, and that the species included in the latter should 

 strictly speakiug form only a section of the former.

This common Indian species also occurs in Penang ; I only obtain- 

 ed it on two occasions, both times on the pillars of the verandah ; 

 it seems to have been expelled from the interior apartments by the 

 much stronger Peripia Peronii. 



It is also found in Burma, in the whole of Lower Bengal, at the 

 Andamans, where it seems to attain a larger size, and at the Nicobars. 

 The thumb and inner toe are always particularly small but with dis- 

 tinct claws ; the middle portion of the back does not usually have any 

 enlarged tubercles, but sometimes there are two alternating rows of 

 them, the three rows on each side are, however, pretty constant. The 

 tail when reproduced, usually becomes smooth, without enlarged 

 spines. In an Andaman specimen, the subcaudal plates are very 

 considerably enlarged. Specimens from Rangoon have a very con- 

 spicuous broad whitish band from the nostril continuing through 

 the eye to above the ear ; it is bordered below by black. The 

 Nicobar specimens are small and have mostly only 36-38 series 

 of scales on the belly ; the thumb is almost obsolete, but there 

 is no other specific difference. They were obtained on trees on 

 Camorta, near the new settlement. The largest specimen I saw 

 is from Moulmein, itmieasures 5^- inches with the tail 3 inches.

This is very common about Moulmein, The number of upper 

 labials varies between 1 1 and 13, the last 4 or 5 being as usually very
