406 NOTES ON [October, 



genus Agama. It has been distinctly described under 

 the specific name undulata by Bosc, Daudin, &c. and is 

 now the Agama undulata of authors. 



Lacerta fasciata, ibid. This animal I have always 

 been accustomed to consider either as the female of the 

 preceding, or as that animal in a state of vernantia, or of 

 old age. But within a few days having had an opportunity 

 to observe several living individuals of the undulata in 

 the vicinity of this city, I was confirmed in the opinion 

 that the Jasciata is no other than the female of that spe- 

 cies. That those in which the blueish colour is wanting 

 are not males in a state of desquamation was evident, as 

 one of the individuals alluded to was about casting his 

 skin, and the blueish colour of the sides was still visible 

 though obsolete. This opinion is corroborated by the 

 observations of Mr. Titian Peale, who informs me that he 

 has dissected numbers of these animals, and that those 

 which were destitute of the blueish colour and of the 

 whitish cruciate mark beneath, proved to be females. 



Salamandra rubriventris, var, ibid., appears to me to 

 be the S. rubra of Daud., notwithstanding the ventral 

 colour and semipalmated feet attributed to this last. The 

 rubra is sprinkled with rounded, blackish points, more 

 numerous above, about the size of pins' heads according 

 to Daudin, and the tail is acutely carinated as in our spe- 

 cimens. The spots of the former are represented as be- 

 ing on a greenish brown ground, large, irregular and late- 

 ral; in these and other respects manifestly distinct. 



Proteus JVeo- Cas^ensis, ibid. Judging from the de- 

 scription, this is the same species as Siren operculata of 

 Mr. Beauvois. It is described and figured in the Trans. 

 Amer. Philos. Soc. vol. iv. Shaw supposes it a variety of
