SINCE my return to this country in the end of July 1869, I have been more or less 
oceupied in the examination of the collections made by me in the course of the three 
preceding years, and I now venture to lay before the Linnean Society a first instalment 
of my results, which, although for unavoidable reasons much more limited than I could 
have wished, are yet, I hope, not without a certain amount of value. My collection of 
Mammalia chiefly consisted of a series of human crania (including those of the aborigines 
of Peru, Chili, the Chonos archipelago, Patagonia, and Fuegia), of which the greater 
number are now in the Museum of the Royal College of Surgeons, and of a few skins 
and skulls of quadrupeds obtained in Brazil, Patagonia, and the island of Chiloe. The 
Ornithological collection amounted to between one hundred and twenty and one hundred 
and thirty specimens, for the most part obtained in the Strait of Magellan and on the 
west coast of Patagonia, and now deposited in the University Museum at Cambridge, while 
the remaining Vertebrates, together with the entire collection of Invertebrata, were sent 
to the British Museum. 
The Reptiles, Amphibia, Fishes, Mollusca, and Crustacea I have carefully gone over 
within the last few months; and as I find that a certain number of the species are appa- 
rently altogether undescribed, and that many others are new to the national collection, 1 
have drawn up the following brief account of them. I wish, at the outset of these re- 
marks, to express my deep sense of the obligations which I lie under to the gentlemen of 
the Zoological Department of the British Museum for the facilities which they have | 
afforded me in the examination of specimens and the consultation of books; and I may 
here state that my thanks are especially due to Dr. Günther for much valuable advice and 
assistance in the naming of the Vertebrata, and to Dr. Baird for various suggestions in 
connexion with the Mollusca. The collection was but a small one, as will be gathered 
from the sequel; but every naturalist who has had the opportunity of undertaking a 
long sea-voyage will appreciate the difficulties arising from confined space and a variety 
of other circumstances inseparable from life on board a small ship, and will therefore, I 
trust, make due allowance accordingly.
