north or west than the Eastern Himalayas. Its species are found 

 in dense '' equatorial " forests. Those that occur in our area are 

 G. g'ubernatoris , G. rubidus, G. himalayicits and G. khasiensis. 



Group IV. Type: Gymnodactylus nebulosus, Beddome. 



The species of this group are stoutly-built arboreal lizards 

 with comparatively short tapering tails, which are probabl}'' pre- 

 hensile and never have subcaudal plates. The colouration is 

 always very conspicuous. The dorsal lepidosis varies consider- 

 ably. All the species known are found in Peninsular India, 

 Burma and Ceylon, none occurring in Assam and the Himalayas 

 or in Malaysia, and only one in Burma. They are G. oldhamii, 

 G. triedrus, G. jeyporensis, G. nebulosus, G. deccanensis and G. 

 albofasciaius. 



Group V. Type : Cyrtodactylus pulchellus, Gray. 



The lizards associated with this species resemble those of 

 group III in general structure and in habits, but are distinguished 

 from them by their conspicuous colouration and by the fact that 

 transverse plates are always developed under the tail. Some 

 species attain a fairly large size. The headquarters of the group 

 appears to be in Burma, whence no less than five species are 

 known ; several occur in Malaysia, one in Ceylon and one in the 

 Western Himalayas. The species from India, Burma and Ceylon 

 are G. pegiie?isis, G. consobrinoides , G. fasciolatus, G. frenatus, 

 G. pulchellus, G. variegatus and G. feac. 



G. lawderanus cannot be definitely assigned to any of these 

 groups but ma3^ be associated provisionally with G. stoliczkai. It 

 is only known from a single deformed specimen. 



The genus as a whole has a remarkable distribution, ranging 

 from the shores of the Mediterranean through the mainland of Asia 

 to the Malay Archipelago, Australia, Oceania, S. America and the 

 West Indies. Most of the northern forms belong to my group I ; 

 the Malaysian species are distributed in groups III and V ; all 

 others probably belong to groups not represented in the Indian 

 fauna. Apparently there are no true Ethiopian species. In the 

 following paper, for the sake of reference, I either quote already 

 published descriptions or give new ones of the species described 

 since the issue of the Fauna of British India, Reptiles and Batrachia 

 (1890). 



In the notes on the different species I have included, under 

 the heading of each, a list of the specimens in the collection of the 

 Indian Museum. A large proportion of these were obtained by 

 zoologists now no longer living, notably by Blyth, Stoliczka, W. T. 

 Blanford, Theobald and Wood-Mason. Of recent years we have, 

 in addition to specimens collected by the staff of the Museum, 

 received examples of rare species from Mr. C. G. Rogers, I.F.S..
