Description of the Cirrhipeda, Conchifera, and Mollusca, in a Collection formed by the Officers of H.M.S. Adventure and Beagle, employed between the years 1826 and 1830 in surveying the Southern Coasts of South America, including the Strait of Magalhaens and the coast of Tierra del Fuego. By Captain Phillip P. King, R.N., F.R.S., &c., assisted by W. J. Broderip, Esq., F.R.S., &c. (From the Zoological Journal.)
The testacea, of which the following paper is a descriptive list, were principally collected upon the coast of South America; and, upon my arrival in England, were submitted to the examination of Mr. George Sowerby; who very obligingly selected the undescribed species from the collection which had been formed under my superintendence by the Officers of H.M.S. Adventure and Beagle, employed under my command in surveying the southern coast of South America.
To these gentlemen I am greatly indebted for the unwearied assiduity which they at all times displayed, and for the extent of the collection in this, as well as in other departments of Natural History.
In the description of the species I have had the benefit of the advice and assistance of my friend Mr. Broderip; and to his knowledge of the subject, and the attention which he has devoted to my collection, I owe in a great measure the paper which I have now the satisfaction of presenting to the public through the medium of the Zoological Journal.
Upon examining my specimens, Mr. George Sowerby found that he possessed several species not in my collection. These had been obtained during the voyage, and had been purchased from some of the crew by Mr. Sowerby, who handsomely put his acquisitions into my hands for description.
