been completely '' worked out," the greater and the more important part 

 of its zoology has still to be investigated. 



To return to the Andaman lizards. Of the Agamids, one, Galotes 

 andamanensis^ , is known from a single specimen in the Copenhagen 

 Museum ; it is allied to G. liolepis of Ceylon. Another is G. mystaceiis,^ 

 which has a somewhat restricted range on the mainland of S.E. Asia 

 and is common about Mandalay.^ Major Anderson tells me that, in the 

 Andamans, 0. versicolor is found only in the Cocos group, not south of 

 Table Island. It is essentially a mainland form and does not, as a 

 general rule, penetrate into primaeval jungle. In the Siamese Malay 

 States it is only to be met with in cultvated land or secondary jungle 

 and I believe that this is also true of India. It generally lays 

 its eggs at the base of bushes in hedges or plantations. According 

 to Prain (11), there are several cultivated plants which have run 

 wild in the Cocos, and if these were brought from the mainland 

 or elsewhere as plants, it is quite possible that the eggs of this 

 lizard may have been brought with them. Although it has been 

 recorded from the southern districts of the Malay Peninsula, G. versicolor 

 is rare south of the Perak and Kelanfcan Rivers, its place being 

 taken by G, cristatelluSj which is closely allied to 0. juhatus of 

 the Nicobars and Malayan Islands. The southward range of G. 

 versicolor as a common member of the local fauna is greater on 

 the eastern than on the western side of the mountains which form 

 the backbone of Malaya,* as is also the case with of a number of other 

 animals. 



Gonyocejohalus suhcristatus, on the other hand, is peculiar to the Anda- 

 mans and the Nicobars. G. humei (Stol.) also occurs in the latter islands, 

 but I do not think that this species can be maintained. We have in the 

 Museum two males from Tillinchong identified as Tiaris humei by 

 Stoliczka and possibly the types of the species. From the same island we 

 have a normal specimen of G. siihc7'istatns, also named by Stoliczka ; but 

 in a series from Kondal (an island in the other division of the Nicobar 

 group), identified by the same authority as belonging to the latter species, 

 I find a female which must be associated with the two males from Tillin- 

 chong. These three specimens are distinguished from the whole of a

2 I have found a well-anthenfcicated specimen of this species from the 

 Andamans in the Museum collection, which also contains several of G. veisicolor 

 from the Cocos.

* It is convenient to confine this term to the Malay Peninsula, using " Malaysia" 

 for the Malay Archipelago.
