Show 544 SIR E. NEWTON AND DR. H. GADOW ON THE DODO. [Nov. 1, fact that up to the present time, beside bones of Didus ineptus, those of the following birds have been obtained from this marsh and described as under :- Lophopsittacus mauritianus Lower Jaw. Owen, Ibis, 1866, (Owen). pp. 168 et seqq. Tibia. A. Milne-Edwards, Ann. Sc. Nat. ser. 5, vi. pp. 88 et seqq. (1866). Astur, sp. indet Metatarsus. Id. op. cit. xix. art. 3 (1874). Ardea yarzetta, Linnseus. Tibia. Id. loc. cit. Aphanapteryx broecki Lower Jaw, Tibia, Metatarsus. Id. (Schlegel). op. cit. x. pp. 325 et seqq. (1868). Fulica newtoni, A. Milne- Pelvis, Tibia, Metatarsus. Id. op. cit. Edwards. viii. pp. 195 et seqq. (1867). All these are species which no longer occur in the island. Bones of a species of Phcenicopterus have also been found (G. Clark, Ibis, 1866, p. 144, and A. Milne-Edwards, Ann. Sc. Nat. ser. 5, xix. art. 3). The present collection contains not only bones of the above-named birds, but also those of a Finch (?), an Owl, four other species of Heron or Bittern, a Darter, a Gannet, a Goose, a Duck, a Grebe, two species of Pigeon, one of which is probably the extinct Funingus (Alectoroznas) nitidissimus, a Waterhen, and two Petrels, of which we proceed to describe and characterize as new :- Strix (?) sauzier i, Astur alphonsi, Butorides mauritianus, Plotus nanus, Sarcidiornis mauritianus, and Anas theodori. In naming these species we wish by the first and last to commemorate the services to science of Mr. Sauzier ; while tbe Astur, being in all probability identical with that, recognized but left unnamed by Professor Milne-Edwards, may be appropriately dedicated to him. Of birds previously distinguished we have now for the first time the following parts :- Didus ineptus.-Atlas, Prepelvic or "intermediate" (18th) Vertebra, complete Pubic Bones, and Metacarpals. Lophopsittacus mauritianus.-Sternum, Femur, Metatarsus, besides Lower Jaw far larger than that first described. Aphanapteryx broecki.-Skull with Upper Jaw, third Cervical Vertebra, Pelvis, Humerus, Femurl. Fulica newtoni.-Cervical Vertebrae (third and ninth or tenth), Sternum, Sacrum, Humerus, Ulna, and Femur l. 1 There is a large series of tibiai (39 right and 50 left), which must belong to one or the other of these two species, but except in a few cases it is impossible to distinguish between them. |
