48. THE WILD SWAN. Cygnmferus, Ray. Le Cygne sauvage. 



The remains of this species are rare in the Caves ; one can understand that 

 their conveyance thither would require a concurrence of exceptional circum- 

 stances. In fact, the Wild Swan inhabits the Polar regions; and when it 

 migrates in winter, it follows in preference the sea-shore, and only accidentally 

 makes its appearance inland. Nevertheless I possess a tarso-metatarsal of this 

 hird, collected by M. J. Desnoyers in the Cave at Arcy sur Cure; and among 

 the fossils taken out of the Gourdan Cave by M. Piette I have recognized a 

 portion of an ulna which must be referred to this species. At La Madelaine and 

 Massat some fragments of ulnas of large dimensions, probably also from the 

 same species, have been found ; but the exact determination of these bones pre- 

 sents almost insurmountable difficulties, because their articular extremities have 

 been detached, probably for the purpose of making pipes of the diaphyses. 



49. THE WILD DUCK. Anas boschas, Linne. Le Canard sauvage. 



I have recognized numerous remains of the Wild Duck in the ossiferous deposit 

 of Bruniquel, and at Gourdan and Les Eyzies. 



50. THE SUMMER-TEAL. Anas querquedula, Linne". La Sarcelle d'e'te'. 



I have likewise found, in the osteological collection formed by M. Brun at 

 Bruniquel, a tarso-metatarsal and a metacarpal of the Teal.

51. THE DUCK. Anas - 



M. Piette has submitted to me several bones from the Cave at Gourdan, which 

 belong to a Duck of large size, with very short legs, and allied to the Eider, from 

 which, however, it differs too much for me to identify it with that species. 



I will now give a list of the species enumerated above, arranging them according 

 to the places from which they have been obtained : we may derive therefrom some 

 information which will not be without its use.
