116 CARINATiE. 



Anas meyeri, Milne-Edwards '. 



A very imperfectly known species of considerably smaller size 

 than A. jicecihrJii/ncJius, and characterized by the extreme shortness 

 of the tarso-metatarsus, in which it approaches FuUyula. 



Hah. Europe (Switzerland). 



42805. Fragment of rock, showing the tarso-metatarsus and foot in 

 {Fig.) an imperfect and laterally crushed condition ; from the 

 Upper Miocene of (Eningen. The type ; described and 

 figured by Meyer in the ' Paloeontographica,' vol. xiv. 

 p. 130, pi. XXX. fig. 4, without generic determination ; 

 also figured in Heer's ' IJrwelt der Schweiz,' 2nd ed. 

 p. 434, fig. 367; noticed by Milne-Edwards in his 'Oiseaux 

 Fossiles de la France,' vol. i. pp. 128, 129. 



Van Breda Collection. Purchased, 1871. 



Anas velox, Milne-Edwards^. 



An imperfectly known species of the dimensions of Qucrqiiedula crccca, but 

 distinguished by the greater length of the wings. It should in all probability 

 be referred to Querquedida, 



Hah. Europe (France). 



From the Middle Miocene of Sansan (Qers). 



Anas sansaniensis, Milne-Edwards^. 



A species nearly as large as A. boscas. Known by the distal extremities of the 

 humerus and tibio-tarsus, which present well-marked distinctive characters. 

 Hab. Europe (France). 

 From the Middle Miocene of Sansan. 



Anas robusta, Milne-Edwards^. 



Founded upon the distal extremity of the humerus, which indi- 

 cates a species of the size of Anser albifrons ; referred to Anas on 

 account of the form of the surface for the brachialis anticus. 



Hah. Europe (France and [?] Bavaria). 



Typically from the Middle Miocene of Sansan (Gers). 



48165*. The distal extremity of a left tarso-metatarsus perhaps 

 referable to a female of this sjjecies ; from the Middle 

 Miocene of Lierheim, near Hahnenberg, Bavaria. This 

 specimen is considerably larger than the corresponding 

 bone of A. boscas. Purchased, 1877.
