6, Agama tuberculata, Gray. 



Several specimens from Chitlong, I^ittle Nepal Valley, and two 

 from near Simla (8,000 feet). 



In Kumaon this species is common as low as 4,000 feet, and I 

 have seen it even lower. It has been taken, however, in the western 

 Himalayas as high as 12,000 feet. It would appear to range con- 

 siderably further east in the Himalayas than any other species of the 

 genus ; but Agama himalayana, which was originally described from 

 Ladak, is found, north of the hills, in the Lhasa district. Despite 

 the fact that it must be able to endure a very low temperature when 

 hibernating during winter, A. tuberculata is sensitive to cold while 

 active. It is found as a rule on bare rocks, and even on the walls of 

 houses, on which the sun is shining. Even a passing cloud causes 

 it to retire immediately. The posterior surface of the thighs and 

 the throat were suffused with sky-blue in male specimens taken 

 (both in Nepal and in Kumaon) in September and October. The 

 young are apparently hatched at that time of year in Nepal. 



We have long had in the Museum specimens of the species from 

 Kashmir and from Quetta. The species is abundant in the Simla 

 hills, but specimens from this district differ in colour from those 

 taken in Kumaon and Nepal. In the eastern race the dorsal surface 

 is of a very dark slate-colour, with numerous spots and blotches of 

 yellow ; while in the Simla form the back is of a rather pale 

 brownish-grey with fewer and less conspicuous spots. The Simla 

 form is more wary and agile than the eastern one. 



7. Mabuia macularia (Blyth). 



A single specimen from the Terai (sub-Himalayan plain) near 

 Raxaul. 



8. Lygosoma sikkimense, Blyth, 



Numerous specimens from Chitlong, Little Nepal Valley, and 

 one from Katmandu. 



This species appears to be as common in the Little Nepal Valley 

 as it is in British Sikhim. There is no evidence that it ranges further 

 west than Nepal and it is certainly replaced in Kumaon by Lygosoma 

 himalayanum. I recently recorded a specimen from Simla {Journ. 

 Asiat. Soc. Bengal, 1905, pp. 146, 149), but a re-examination of this 

 specimen which is in a bad state of preservation , convinces me that 

 I was wrong in my identification. L. sikkimense is fond of sunning 

 itself on stonej and dry paths. 



9. Lygosoma himalayanum (Giinth.). 



A single specimen from Chitlong. 



This specimen (plate vi, fig. 3) is not quite typical. Its total 

 length is 168 mm., of which the tail accounts for 108 mm. ; the 

 colours are brighter than usual and the longitudinal streaks more 

 conspicuous, but it is difficult to find any very definite difference
