[Received January 16th, 1871.] In May 1852, the Swedish Frigate 'Eugenie' (Commander Virgin), on its voyage round the world, visited the Galapagos Islands, chiefly for the purpose of making scientific observations and collections. Nine days elapsed from its coming to its departure; but of these, two whole days were lost, owing to the vessel being becalmed in the offing. The frigate called successively at the islands of Chatham, Charles, and James; and, in addition, the naturalists attached to the expedition made an excursion in one of the boats to Albemarle and Indefatigable Islands. Notwithstanding the very wet weather, the collections made were considerable, the naturalists being kindly assisted, here as in every other part of the voyage, by the Commander and all the officers, and even by the crew. Dr. Kinberg, the zoologist and surgeon of the expedition, took the trouble to determine, or have determined by others, the sex of almost every specimen of the birds, and to attach to it the name of the island on which it was found. The voyage has been described by Lieutenant Skogman, in two volumes, large 8vo, with charts and illustrations (Stockholm, 1854), and by Mr. Anderson, botanist to the Expedition, in three volumes, small 8vo (also published in 1854). The following is the list of the birds brought home. Most of the species are mentioned by Darwin in the ' Zoology of the Beagle- Birds,' 1841, and described there, or in this Society's ' Proceedings,' by Gould: these references, therefore, need not be quoted. Only nos. 15 and 24 are supposed to be new. Those which are new to the archipelago have a t prefixed: these are mostly water-birds, and probably only make a short stay there during the winter or for breeding. The following abbreviations are used to denote the islands on which the land-birds were taken:-Chm., Chatham; Ch., Charles; J., James ; Alb., Albemarle ; and Ind., Indefatigable. 1.
