462 ME. 0. SALVIN ON THE AVIFAUNA 



Subsequently to Mr. Darwin's expedition, the archipelago was visited by the French 

 ship ' Venus ' in 1836-39 ; and a small collection of birds appears to have been made by 

 the Surgeon Neboux. One of these was characterized by the late Baron de la Fresnaye 

 as Camarhynchus cinereus, in the ' Magasin de Zoologie' for 1843. Others are described 

 by Prince Bonaparte as Zonofrichia galapagoensis (Conspectus Avium, i. p. 479), and 

 Procellaria tethys (Notes Ornithologiques, p. 92). The last named was probably 

 obtained during the visit of the ' V^nus ' to the islands ; but the locality ascribed to the 

 former I show elsewhere to be erroneous. 



"Dr. Habel's visit was made in 1868. Though he touched at Hood, Albemarle, 

 and Tower Islands, no birds were collected. From Indefatigable Island, however, a 

 large and important series of birds was obtained ; and more important still are his 

 collections from the more northern outlying islands of BLndloe and Abingdon. 

 Neither of the last-named islands had before or since been visited by any naturalist. 

 A brief summary of Dr. Habel's collection, with descriptions of the new species, was 

 drawn up by Mr. Sclater and myself, and published in the Society's ' Proceedings ' for 

 1870. The same collections, with the addition of Dr. Habel's notes, now form the main 

 source whence the present Memoir is derived. 



Since our paper was published, the veteran ornithologist Sundevall has communicated 

 to the ' Proceedings ' of this Society for 1871 a list of the collection of birds made by the 

 officers of the Swedish Frigate 'Eugenie' as long ago as 1852. Two new species are 

 described in this paper; and some careful notes are added on several of the species 

 mentioned. The islands explored were Charles Island, Chatham Island, and James 

 Island, which were also touched at by the ' Beagle.' Indefatigable Island was also 

 visited, where Dr. Habel collected largely. Albemarle Island is alluded to as having 

 been called at ; but no species of birds are mentioned in the list as having been 

 obtained there. 



These papers include all that has been especially written on the birds of the 

 Galapagos Islands ; but allusions to Mr. Darwin's visit have been frequently made, 

 not only by Mr. Darwin himself in the narrative of his voyage as well as in others 

 of his well-known works, but also by Sir Charles Lyell, in his ' Principles of Geology,' 

 and by other writers. 



The ground is classic ground ; and the natural products of the Galapagos Islands 

 will ever be appealed to by those occupied in investigating the complicated problems 

 involved in the doctrine of the derivative origin of species.
