544 SIR E. NEWTON AND DR. H, GADOW ON THE DODO. [NoV. I, 



fact that up to the present time, beside bones of Bidus ineptus, 

 those of the following birds have been obtained from this marsh and 

 described as under : — 



Lophopsittacus mauritiajius 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). 



^*?Mr, sp. indet Metatarsus. Id. op. cit. xix. art. 3 



0874). 

 Ardea garzetta, 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 oi Plicenicopterus have also been found (G. Clark, 

 Ibis, 1866, p. 144, and A. Milae-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 

 (Alectoroenas) nitidis simus., a Waterhen, and two Petrels, of which we 

 proceed to describe and characterize as new : — 



Strix (?) sauzieri, 



Astur alphonsi, 



Butorides mauritianus, 



Plotus nanus, 



Sarcidiornis mauritianus^ and 



Anas theodori. 



In naming these species we wish by the first and last to com- 

 memorate the services to science of Mr. Sauzier ; while the Astur, 

 being ir> all probability identical with that recognized but left un- 

 named 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) Ver- 

 tebra, complete Pubic Bones, and Metacarpals. 



Lophopsittacus mauritianus. — Sternum, Femur, Metatarsus, be- 

 sides Lower Jaw far larger than that first described. 



Aphanapteryx broecki.— ^k\x\\ with Upper Jaw, third Cervical 

 Vertebra, Pelvis, Humerus, Femur \ 



Fulica newtoni. — Cervical Vertebrae (third and ninth or tenth). 

 Sternum, Sacrum, Humerus, Ulna, and Femur \ 



1 There is a large series of tibias (39 right and 50 left), which must belong to 

 one or the other of these two sjDecies, but except in a few cases it is impossible 

 to distinguish between them.
