Lizards from Central Australia. 265 



gi"oin. Under surfaces brownisli-grey with scattered brown 

 dots. Tail brown above with Hghter ocelli, each occupying about 

 four scales ; below with intermingled grey and brown scales. 



Since Mr. Boulenger has withdi'awn his species E. l>oettgeri, 

 (Cat., vol. iii., p. 482), only one Ehenavia has been previously 

 recognised, and that only from Madagascar. In general outline 

 the present species closely agrees with Mr. Boulenger's figure 

 (Cat., vol i., pi. viii., fig. 1), and the colour bands agree fairly with 

 those of his Madagascar specimen. The chief point of distinction 

 in the Australian form is the entire absence of anything like 

 longitudinal series of large tubercles. 



The nearest allies to the clawless genus Ebenavia are met with 

 in the genus Phyllodactylus. Species of Phyllodactylus occur in 

 South Africa and Madagascar. Indeed, only the most trivial 

 differences can be found between P. porphyreus, Daud., from 

 these localities, and the widely distributed Australian form 

 P. marmoratus, Gi-ay. 



We have associated the name of Mr. Horn with this interesting 

 lizard. 



Tyvipanocryptis tetraporophora, sp. nov. 



Nostril nearer to eye than to tip of snout ; upper head scales 

 larger and less strongly keeled than in T. Hneata, Peters, large 

 on the occiput. Dorsal scales strongly keeled, the enlarged ones 

 mucronate. Colour. — Light brown above or reddish, with darker 

 more or less indistinct cross bands on the body ; tail and limbs 

 with dark bars. Resembling T. cephahis, Uiinth., in colouring 

 above, and T. lineata on ventral surfaces ; but in one of the two 

 specimens there is a narrow white vertebral line recalling that of 

 T. lineata.
