134 NELLY DE ROOY. REPTILES. 



The maie spécimen from Alkmaar has a total length of 132 mm.; the female from 

 Hill Camp of 146 mm. The young one from Bivak Island is in a bad condition of préser- 

 vation. This form, widely spread in the Indo-Australian Archipelago is found from the Malay 

 Peninsula to New Guinea in many of the islands between.

Boulenger describes a maie spécimen from Gerekanumu, which has an angular séries of 

 14 praeanal pores, separated from 17 indistinct fémoral pores on each side, 48 pores together. 

 Lônnberg gives a long description about 5 spécimens from Sattelberg, of which one is a maie, 

 one female and two are young ones. The maie has an uninterrupted séries of about 30 pores 

 on each side, forming a right angle in the middle, and a distinct praeanal groove. As to 

 the coloration, the maie shows 5 dark cross-bands on the body, the female only four and 

 the 2 young ones are brown above with narrow undulated bands of a darker shade across 

 the back. 



Werner compares three examples of a Gymnodactylus from New Guinea, two adults and a 

 young one, with the descriptions of G. louisiade?isis and G. loriae. He cannot corne to a conclusion, 

 whether they belong to the one or the other species, because they show sorae characteristics of the 

 one, others of the other. They are females, so that nothing can be said of the fémoral pores. 



From the spécimens, known till now, ail differ slightly in the coloration and the maies 

 in the number of the pores. 



The maie from Alkmaar has an uninterrupted angular séries of 44 pores; maie and 

 female hâve 6 blackish cross-bands. The Sabang spécimen is a young one, 106 mm., with 

 smooth dorsal tubercles and 5 dark cross-bands between the occiput and the base of the tail. 



Among the 1 1 spécimens, captured by the last Dutch Expédition, there are 7 maies. 

 Ail hâve an uninterrupted séries of fémoral pores, the number varying between 34 and 45 ; 

 there is no praeanal groove. The smallest spécimen measures 182 mm., the largest 267 mm.; 

 there are maies and females with 5 dark transverse bands, with 6 bands and one maie with 

 7 bands between the occiput and the base of the tail. 



The species is found over the whole of New Guinea although comparatively rare, and 

 in the islands eastwards of New Guinea: Sudest Island, Rossel Island, Fergusson and Wood- 

 lark Islands; Solomon Islands and in Queensland.
