228 GEOKONIDJ!. 



The folio-wing genus, characterized by Gray in 1842, has never 

 been rediscovered ; the type is not to be found in the CoUeotion. 

 If the description is correct, this Gecko constitutes a distinct genua. 



Phteia, Gray, Zool. Misc. p. 53. 

 " Toes moderate, base scaly above and below, dilated, ends ex- 

 panded into a rounded disk, with two series of diverging plates be- 

 neath, last joint free, compressed, clawed; thumb of fore and hind 

 feet smaller, clawless ; back covered with small granular, belly with 

 rather larger scales ; labial and chin-shields distinct ; tail round, 

 tapering, with a series of large hexagonal plates beneath ; prseanal 

 pores distinct, in an angular hne. Like Ptyodactylus, but the toes 

 are shorter, thicker, dilated at the base, and it has prasanal pores." 



Phyria punctulaia, Gray, Z. c. 



" Olive-grey, in spirit ; scales minutely black-speckled ; lips, 

 sides of throat, chest, belly, and underside of tail yellow."

The following bones of an apparently extinct Lacertilian, from 

 Rodriguez, have been referred to Gecko (Gecko newtonii, Giinther, 

 Journ. Linn. Soc, Zool. xiii. 1878, p. 324), which generic identifica- 

 tion seems to me extremely doubtful, the parietal bone being single, 

 whereas it is double in all known Geckoids.
