ground, which is so much undermmed by them that it gives way 

 at almost every step. It is a timid little fellow, feeds upon grass, 

 and is eaten by the Patagonian Indians. — See Bennet in the Pro- 

 ceedings of the Zool. Soc. Dec. 22, 1835. A specimen is preserved 

 in the Museum. 



10. Keroda Kingii. n. s. 

 See Bennet ut supra, in Museum of Zool. Soc. 



11. Cavia Cutleri, n. s. nob. — See Bennet ut supra. 

 This specimen is in the collection of the Society. It was known 



in the voyage by the name of the Peruvian cavy : it was pre- 

 sented to one of the officers of the Beagle by an American sailing 

 master, Mr. Cutler, of Stonington, U.S., a very intelligent person, 

 to whom we are much indebted for information. The name which 

 I have proposed for it is in recollection of the benefit we derived 

 from his experience and knowledge of the intricate navigation of 

 the south-western coast of Patagonia, which was freely imparted 

 to us on several occasions. — See Bennet in Proceedings of Zool. 

 Soc. ut supra. 



12. Dasyprocta Patachonica. — Desm. E. M. 358. 



I regret very much that the only specimen obtained was 

 not preserved. Desmaret seems to suspect that it differs suffi- 

 ciently in its dentition from the agouti to constitute a new genus, 

 for which he has proposed the name Dolichotis. — See E. M. 359. 



13. Dasypus minutus.— Desm. 

 Procured at Port Elena, and corresponds exactly with the 

 description of the above species. It is the Tatou pichiy, or 

 Tatou septieme of D'Azara. 



14. AucHENiA Glama. — Dcsm. E. M. 655. 

 A living female guanaco was brought home in the Adven- 

 ture, and placed in the garden of the Zoological Society. The 

 guanaco inhabits Patagonia from Buenos Ayres to the Strait of 

 Magalhaens: we also found it on King Charles Foreland, the 

 eastern island of Tierra del Fuego, and on Navarin Island, at the 

 north side of Nassau Bay, in the vicinity of Cape Horn.
