In preparing the following pages for the press, I have endeavoured to give a brief account, divested as much as possible of technicalities, of the principal points of interest in Natural History which came under observation during the wanderings of a surveying ship; while at the same time I have done my utmost, at the risk of rendering the narrative disconnected, to avoid trenching on ground which has been rendered familiar by the writings of travellers who have visited the same or similar places. And if in a few instances I have given some rather dry details regarding the appearance and surroundings of certain zoological specimens, it has been my intention, by an occasional reference to the more striking forms of life met with in each locality, to afford some assistance to those amateurs who, like myself, may desire to avail themselves of the opportunities afforded by the surveying ships of the British Navy for performing, although with rude appliances and very few books of reference, some useful and interesting work.

Large collections of zoological specimens were made, and as these accumulated on board, they were from time to time sent home to the Admiralty, whence they were transmitted to the British Museum, the authorities of that institution then submitting them to specialists for systematic description. For much kindly aid in making these arrangements, as well as for advice and encouragement received during the progress of the cruise, I am indebted to Dr. Albert Günther, F.R.S., Keeper of Zoology in the British Museum.

I take this opportunity to thank Mr. Frederick North, R.N., for the use of a collection of photographs which were taken by him during the cruise under circumstances of peculiar difficulty, and of which most of the engravings in this work are reproductions.

I am also under obligations to all the other officers for assistance rendered to me in various ways; and especially to those officers who acted successively as Senior Lieutenants, for the consideration with which they tolerated those parts of my dredging operations that necessarily interfered with the maintenance of good order and cleanliness on the ship's decks.

Finally, I have to thank my friend, Mr. R. Bowdler Sharpe, the distinguished ornithologist of the British Museum, by whose advice and encouragement I was induced to submit these pages to the public, for his assistance in perusing my MS., and offering some useful suggestions.

In the summer of 1878 it was decided by the Lords of the Admiralty to equip a vessel for the threefold purpose of continuing the survey of the Straits of Magellan, of investigating the nature and exact position of certain doubtful reefs and islands in the South Pacific Ocean, and of surveying a portion of the northern and western coasts of Australia. The special object of the Magellan portion of the work was to make such a detailed survey of the sheltered channels extending southward from the Gulf of Peñas to Port Tamar as would enable vessels to pass from the Straits to the Pacific, and vice versâ, without having to encounter the wild and inhospitable outer coasts presented by the chain of desolate islands here fringing the western coasts of South America. It was also desirable that additional anchorages should be found and surveyed, where vessels might lie in safety while waiting for the cessation of a gale, or for a favourable tide to help them through the straits. The surveys made by the Adventure and Beagle in 1826–36, and by the Nassau in 1866–9, were excellent so far as they went, and so far as the requirements of their times were concerned; but the great increase of ocean navigation within the last few years had rendered it necessary that the charts should contain more minute surveys of certain places which were not formerly of importance. The South Pacific portion of our survey was to be mainly in connection with the recently acquired colony of the Fiji Islands, and was to be devoted
