OBSERV. We do not see the propriety of adopting the genus Platy- 

 urus for the present species, as proposed by John Edward Gray, having 

 failed observing the characters which he assigns to it. The materials 

 at our command, however, are somewhat deficient ; and, we should 

 have considered it premature to discuss this subject to any greater 

 length. 



Loo. The solitary specimen in the collection is labelled " East 

 Indies." 



GENUS HEMIDACTYLUS, Cuv. 



GEN. CHAR. ^Fingers and toes free, dilated towards their anterior 

 extremity, and all provided with a nail ; plates, underneath, in 

 two diverging series, divided by a mesial groove. Femoral pores 

 present. Body with a slight ridge on the lower part of the sides. 

 Tail subdepressed, provided beneath with large scales or scutellae.

OBSERV. The genus Hemidactylus, as here understood, includes 

 some of the " Dactyloteles fissipedes," of Messrs. Dumeril & Bibron. 

 The limits ascribed to it by various writers appear to us a good deal 

 wider than will hereafter be found expedient, when the species shall 

 have been more thoroughly investigated.
