" Head elongate, oviform, very distinct from neck ; eye 

 moderate, the eyelid not distinct inferiorly ; ear-opening small, 

 linear, oblique. Body and limbs moderate. Tw^o lateral folds 

 of the skin, enclosing a groove. Head covered with granular 

 scales intermixed with larger flat scales, largest and most 

 numerous on the snout. Rostral four times as broad as high ; 

 nostril pierced between the first upper labial and three nasals ; 

 ten upper and as many lower labials ; mental three times as 

 broad as high anteriorly, narrowing posteriorly ; no chin- 

 shields. Back covered with small granular scales intermixed, 

 especially on the sides, with large, roundish, flat or keeled 

 tubercles ; lower-surfaces covered with imbricated scales ; the 

 throat granular. A large patch of prgeanal pores and a single 

 series of femoral pores. Tail cylindrical, covered with irregu- 

 lar scales. Greenish-grey above, with irregular longitudinal 

 and transverse purplish bands on the back ; uniform light- 

 grey beneath. 



" Total length, 14:5mm. ; from tip of snout to ear-opening, 

 17mm.; fore-limb, 20mm.; hind-limb, 26mm.; tail, 82mm." 

 Boulenger. 



We have not had an opportunity of seeing or examining 

 this species ; it would seem to be exceedingly rare. There is 

 no specimen in the Britism Museum. Professor Hutton 

 writes : "I have a single specimen, caught in the northern 

 part of the South Island. It has no longitudinal bands. I 

 have seen no other." 



HoPLODACTYLus, Fitzing. 

 Digits free or shortly webbed at the base, more or less 

 dilated ; the distal phalanges slender, elongate, clawed, form- 

 ing an angle with the basal portion ; a series of transverse 

 lamellae under the latter. Scales small, granular, equal. 

 Pupil vertical. Males with prseanal or praeanal and femoral 

 pores. Of the species grouped in this genus two belong to 

 Bengal and to southern India respectively, and the rest are 

 confined to New Zealand. 



Synopsis of Species. 



I. Dilated portion of digit broad, its breadth equal to the 

 length of the compressed distal phalanges, its length 

 three times as great. Lamellae all curved or chevron- 

 shaped . . , . . . . . . . . . H. maculatus. 



IT. Dilated portion of digit narrow, its breadth much less 

 than the length of the compressed distal phalanges, 

 its length two-thirds that of the digit. Posterior 

 lamellae straight.
