1 52 Zoological Society, 



Specimens were exhibited of several Reptiles, which were accom- 

 panied by notes by Mr. Gray, lliese notes were read. 



Mr. Gray regards the Testudo Spengleri, Walb., as the type of 

 a new genus of Emydidce, having, like lYm fresh-water Tortoises ge- 

 nerally, the toes lengthened and covered by a series of shields, but 

 these members, instead of being webbed as in the other genera of the 

 family, are quite free from each other ; the legs, moreover, are de- 

 stitute of fringe along their outer edge. This structure of the feet 

 and limbs indicates habits less aquatic than those of the Emydida 

 generally ; and Mr. Gray states that such appears to be the case 

 with the Em. Spengleri, for though he has watched for a consider- 

 able time the specimen now living at the Society's Gardens he has 

 never observed it to enter the water. 



From the beautiful figure of the animal of Em. spinosa given 

 by Mr. Bell in his * Monograph of the Testudinata,' Mr. Gray is 

 inclined to believe that this species belongs to the same genus with 

 Em. Spengleri, the toes, especially those of the hind feet, being 

 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\ier fresh-water Tortoises.

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

 the name of 



Gehyiia. 



Digiti 5-5, ad basin dilatati, serie unica squamarum transversa- 

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

 poUices) unguiculati. Pori femorales nulli. 



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