Remarks — 



I have known this lizard, which appears to be not uncommon in 

 the neighbourhood of Naini Tal and Mussoorie, for some time but 

 have hitherto regarded it as the young of A. major, from which it 

 is really quite distinct. It is allied to A. dymondi, Boulenger, 

 from which it is readily distinguished by the absence of parallel 

 rows of keeled scales on the back. There are female specimens 

 in the Museum, taken at Mussoorie in September or October, 

 containing eggs. The only individual 1 have seen in life was a 

 male , it was caught climbing a tree in a garden in the town 

 of Naini Tal. Another male was taken by Mr. L. L. Fermor 

 at an altitude of about 6,000 feet in the same district. The 

 species has evidently a restricted range, which probably does not 

 extend beyond those parts of Kumaon and the Mussoorie district 

 situated at moderate elevations. 



4. Acanthosaura tricarinata (Blyth). 



A single specimen from Chandragiri, Nepal : altitude 8,000 feet. 



The dorsal surface of fresh specimens of this lizard has a livid 

 green colour, which generally fades in spirit to greyish blue. The 

 species is not uncommon at an altitude of 5,000 to 6,000 feet in 

 British Sikhim. 



5. Calotes versicolor (Daud.). 



Several specimens from Katmandu. 



This common species has a somewhat extensive range in the 

 Himalayas. In British Sikhim it occurs at least as high as 7,000 

 feet, and I have seen it at about the same altitude in Kumaon. It is 

 common at 5,000 feet in the Darjiling district and in the neigh- 

 bourhood of Bhim Tal at a slightly lower altitude. Specimens from 

 the Himalayas are generally small and have a somewhat depaupera- 

 ted appearance, the sexual characters being rather feebly developed; 

 but it is not always possible to distinguish between such specimens 

 and examples from Lower Bengal. A female was found in May at 

 Kurseong (5,000 feet) whose oviduct contained large eggs still devoid 

 of a shell. In Calcutta the young are hatched at the beginning of the 

 rains and apparently take at least two years to reach sexual ma- 

 turity. The breeding season is in progress as early as April .
