April 6, 1875. Dr. E. Hamilton, V.P., in the Chair. A letter was read from Dr. G. Hartlaub, F.M.Z.S., in which he stated that Dr. Finsch and he had come to the conclusion, from the study of additional examples, that Lobiospiza notabilis (the supposed new Finch from the Navigator Islands), described and figured by them in the Society's 'Proceedings' for 1870 (p. 817, pl. xlix.) from a single specimen in spirits, was probably only the young bird of Amblyura cyanovirens. Mr. A. G. Butler, F.Z.S., read a " Revision of the Heterocerous Lepidoptera of the family Sphingida." This memoir will be printed in the Society's ' Transactions.' Mr. Osbert Salvin, F.R.S., read a memoir on the Avifauna of the Galapagos archipelago, of which the following is an abstract. The Galapagos archipelago consists of a group of fifteen islands, together with a number of outlying rocks. Of the former, seven are considerably larger than the rest, one of them, Albemarle, being as large as all the others put together. The group is situated about 600 miles from the west coast of Ecuador, and lies under the equator. All the islands are of volcanic origin, the number of craters being computed to be as many as 2000. The most western of the islands, * Montagne de Bogosch aux environs de Zakataly, non loin de la route de Tiflis a Dei-bent, 42° lat, bor., 111° long, cle Ferro. |
