do they altogctlier agree, although they approach most nearly to 

 Kerodon. 



I may add that the Dendrobius Degus of Dr. Meyen, described and 

 figured in the same Paper, is my Octodon Cumingii, the characters of 

 which were laid before the Committee of Science and Correspondence of 

 the Zoological Society in March 1832, and shortly afterwards pub- 

 lished in its " Proceedings," part 2, p. 46, & seqq. Molina's 

 description of his Sciurus Degus differed so greatly from the animals 

 from which mine was taken, and which are still (September, 1834) 

 living in the Society's Gardens, that I hesitated to quote that name as a 

 synonym ; and I am not quite sure whether Dr. Meyen states of his own 

 knowledge, or on Molina's authority, that his animal is called Degus 

 by the natives of Chili. If the former, the synonym can be of course 

 no longer doubtful.

The occurrence of an egg of Bulinus ovalis, brought from Rio de 

 Janeiro by my friend Thomas Miller, Esq. R. N., which I showed to 

 Mr. Broderip as a novelty, led him to suggest to me that the eggs men-

 is there called Bulinus hcemastomus. There can be no doubt of the specific 

 identity of the two individuals, and I know not how to account for the 

 mistake in nomenclature thus detected. Certain it is that the Bu,l. 

 hcEtnastomus has never been brought to Europe from Rio, nor has Bui. 

 ovalis ever reached England from any other Country. The representa-
