represented in the figure as quite free. The shells of the two species 

 agree in being of a pale brown colour above, and in being sharply 

 toothed on the margin ; in both which respects they differ from- the 

 ot\xQr fresh-water Tortoises.

A new genus of Geckotidce is characterized by Mr. Gray under 

 the name of 



Gehyea. 



Digiti 5-5, ad basin dilatati, serie unic^ squamarum transversa- 

 lium integrarum tecti, ad apicem compressi, liberi, omnes (prseter 

 poUices) unguiculati. Pori femorales nuUi. 



This genus is very nearly allied to Platydactylus, Cuv., in the 

 form of the base of the toes ; but the ends of the toes are thin, sim- 

 ple, and compressed, instead of being more widely dilated, and 

 with the \&s,t phalanx affixed along the upper surface. The body is co- 

 vered with small uniform granular scales, and the belly with larger 

 flat scales ; the tail is ringed with square scales, those of the under 

 surface being the largest. 



Gehyra Pacifica. Ge. pallide brunnea albido punctata, subtits 

 alba; occipitis strigd utrinque fasciisque latis irregularibus dor- 

 salibus quinque vel sex pallidis ; artubus pallida marmoratis. 



Long, corporis 2-|- poll. ; cauda, totidem. 



Hab. in Insula qu^dam Oceani Pacifici.
