47444 z. A slightly imperfect left coracoid, probably associated 

 with the preceding spcciuieus ; from Otago. 



Prtsented hi/ (he Trustees of the Otcif/o Museum, 1870. 



Subfamily A n s i; ii i n ^e. 



Typically the tarso-metatarsus is generally more slender, with 

 smaller extremities, than in the Cijgninie ; and the same holds good 

 with regard to the tibio-tarsus and femur. The shaft of the 

 humerus is shorter and tliicker, its proximal extremity greatly 

 enlarged and crossed by a ligamental groove, the delto-pectoral 

 crest long and low, and the impression of the brachialis anticus very 

 deep. The species are mostly of medium size. 



Genus ANSER, Brisson\ 



The type genus. In the humerus the dclto-poctoral crest rises 

 gradually from the shaft, and the coracoid is comparatively stout.

36633. A left ulna, wanting the distal extremity, probably referable 

 to this species ; from the Pleistocene of Grays, Essex. 

 This specimen, of which the proximal extremity is some- 

 what imperfect, agrees in all respects with the corre- 

 sjwnding bone of the existing form. Purchased, 1855.

 Grays. Purchastd, 18-16.
