Lucas and Frost. — O71 Neio Zealand Lizards. 265 



notes as we have been able to add from other sources of the 

 habits and distribution of the New Zealand lizards, will be of 

 use to future workers on the group. 



We have to particularly thank Captain Hutton, of Christ- 

 church, Professor Parker, of Dunedin, and Thomas Cheese- 

 man, Esq., of Auckland, for forwarding collections of New 

 Zealand lizai-ds for examination.

Characters of the Family. 

 External Form. 



Head and body more or less depressed, sometimes bordered 

 by cutaneous expansions. Tongue fleshy, moderately elongate, 

 very feebly incised anteriorly, capable of protrusion out of the 

 mouth. 



Tail presenting almost every possible shape, sometimes 

 prehensile, almost always extremely fragile and rapidly repro- 

 duced. If reproduced it generally assumes an abnormal form 

 and scaling. 



Limbs, both pairs well developed, pentadactyle. The 

 digits vary considerably, and furnish the characters upon 

 which the systematic classification is based. 



Eye and Ear. — The eye generally large, with vertical 

 pupil, covered, as in snakes, by a transparent lid, under 

 which it moves freely, the valvular lids being in most cases 

 rudimentary. The tympanum usually more or less exposed. 



Teguments. 

 Skin nearly always soft, with numerous tubercles or 

 granules on the dorsal surface, and small, imbricated, cycloid 

 or hexagonal scales on the ventral surface. Plate-like scales 

 of the head only around the margin of the gape. The skin of 

 the head usually free from the skull-bones.
