10. KERODON KINGII. n. s.

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

11. CAVIA CUTLERI, n. s. n.o.b.--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 presented 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 sufficiently in its dent.i.tion from the agouti to const.i.tute a new genus, for which he has proposed the name _Dolichotis_.--See E. M. 359.

13. DASYPUS MINUTUS.--Desm.

Procured at Port Sta 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.--Desm. E. M. 655.

A living female guanaco was brought home in the Adventure, 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 Na.s.sau Bay, in the vicinity of Cape Horn.
