Lucas and Fkost. — On New Zealand Lizards. 207 



Brown, lighter beneath ; eight transverse dark bands between 

 the occiput and the base of the tail. 



" Head and body, 44mm. ; tail, 41mm." Botdenger. 



This species differs from G.pelagicus of Girard only in the 

 rows of convex tubercles being smooth and the scales of the 

 abdomen and tail not being keeled. This species was recorded 

 as from New Zealand by A. Dumeril ; we have no other record 

 of this lizard being found there. There are no specimens in 

 the British Museum or in the museums of New Zealand. 

 Perhaps best regarded as a variety of G. pelagicus, which has 

 a wide distribution over the western Pacific, and as doubtfully 

 occurring in New Zealand. 



All the other New Zealand geckos belong to the small 

 group consisting of the closely-allied genera NatiUimcs and 

 Hoplodactyhis. All the species are endemic. 



Naultinus, Gray. 



"Digits free, feebly dilated, gradually narrowing distally, 

 clawed, with a series of transverse lamellae under their entire 

 length. Dorsal scales uniformly granular or intermixed with 

 enlarged tubercles. Pupil vertical. Males with prgeanal and 

 femoral pores." 



The genus is confined to New Zealand. 



Dr. Boulenger, in his "Catalogue of Lizards," has given us 

 the results of his careful investigation of the New Zealand 

 forms. He recognises two species of the genus Naultinus — 

 N. elegans, Gray, and N. rudis, Fischer. A number of others 

 have been described from time to time, but Dr. Boulenger 

 includes all these as varieties of N. elegans. 



The varieties as enumerated by Boulenger are distin- 

 guished entirely by differences ifi colour. We have found 

 slight structural variations, but these have been in no way 

 correlated with the variations in colour.
