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. pallid^ brunnea albido punctata, subtHs 

 alba ; occipitis strigd utrinque fasciisque latis irregularibus dor- 

 salibus quinque vel sew pallidis ; artubus pallida marmoratis. 



Long, corporis 2^ poll. ; caudce, totidem. 



Hab. in Insuld quadam Oceani Pacifici. 



The collection of the British Museum contains a specimen, much 

 discoloured, of what appears to be a second species of this genus. 

 Another species is contained in the Museum d'Histoire Naturelle at 

 Paris. 



A living specimen was exhibited of the Red Viper of the Somer- 

 setshire Downs. It had been sent from Taunton to Mr. Gray, who 

 states that he has compared it very attentively with the black and 

 with the common Viper of England, and that he cannot discover the 

 slightest difference between them except in the shade of the colour. 

 They all agree in having the upper lip shield white, with brown or 

 black edges, and in having a series more or less distinct of lozenge- 

 shaped spots. He consequently refers them all to Viper a Berus, 

 Daud. 



Mr. Gray also states that he believes the Lacerfa adura, described 

 by the Rev. R. Sheppard in the seventh volume of the * Linnean 

 Transactions', to be the male, observed during the summer, of the 

 common Lacerta vivipara, the Lacerta agilis of British authors ; the 

 several characters which were pointed out by Mr. Gray at the 

 Meeting on May 22, 1832, (Lond. and Edin. Phil. Mag., vol. i. 

 p. 461,) being at that season so fully developed as to produce the 

 appearances noticed by Mr. Sheppard in his account of his pre- 

 sumed species. 



Some notes were read of the dissection of a specimen of Azara's 

 Opossum, Didelphis AzartB, Temm., which recently died at the So- 

 ciety's Gardens. The general dissection was performed by Mr. Mar- 

 tin ; that of the organs of generation by Mr. Rymer Jones. 



The animal was an adult male, measuring, exclusive of the tail, 

 1 foot 5 inches, the tail being 1 foot 4 inches in length. 



In illustration of the notes, which are printed in the "Proceedings," 

 preparations were exhibited of the stomach and ccecum, as was also 

 a drawing of the organs of generation and bladder.
