Schm. f. 69-72), ex Haiti, but differing in the greater extent and more purple tinge of the blue of the wings, which in Haitian specimens (agreeing fairly with H.-Schaffer's plate) is of a paler tint. Beneath, the posterior wings are deeper brown, and the markings much less distinctly defined. Hab. 'Guatemala. Mus. nostr. 6. Account of the Zoological Collection made during the visit of H.M.S. 'Peterel' to the Galapagos Islands. Communicated by Dr. A L B E R T G U N T H E R , F.R.S., V.P.Z.S., Keeper of the Zoological Department, British Museum. [Eeceived January 29, 1877.] (Plates XI.-XIII.) The circumstances under which the zoological collection1 described in this paper was obtained are, shortly, the following. By direction of Rear-Admiral the Hon. A. A. Cochrane, who then commanded the Pacific Station, Commander W . E. Cookson proceeded in H.M.S. 'Peterel,' in June 1875, for a short cruise in the Galapagos archipelago. His whole stay was limited to a fortnight, in which time he landed on Charles and Abingdon Islands, and at Tagus and Iguana Coves in the Albemarle Islands. These, at least, were the localities where Commander Cookson, assisted by Staff-Surgeon Bett, collected the zoological objects which, by direction of Admiral Cochrane, have been deposited in the British Museum. Valuable as this contribution to our knowledge of the Galapagos fauna is, it serves at the same time to show how incomplete is our acquaintance with one of the zoologically most interesting stations. But for Commander Cookson's timely visit, the Abingdon Tortoise would, in all probability, have disappeared, unknown as if it had never existed, or leaving only some fragments of its osseous frame. Perhaps we may hope that the success which attended Commander Cook-son's search may encourage others to complete the work commenced by Fitzroy and Darwin. For the convenience of the student of this fauna, it seemed desirable to keep together in a connected form the notices of the various parts of the collection which have been examined and determined by the staff of the Zoological Department. My thanks are due to Mr. McLachlan, F.L.S., for the notice of the Libellulae. 1 Eeferred to at meetings of the Zoological Society last year; see P. Z. S. 1876, pp. 178, 422, 520. |
