180 CARINAT^. 



Larus totanoides, Milne-Edwards '. 



Somewhat larger than L. elega^is, with different proportions in 

 the bones. Length of humerus 0,057, and that of tarso-metatarsus 

 0,037. 



Hub. Europe (Prance). 



Tlie foU owing specimens were obtained from the Lotver Miocene {Upper 

 Oligocene) of Allier, and, unless the contrary is stated, form part 

 of the Bravard Collection. Purchased, 1S52. 



31351. The right humerus, with the proximal extremity imperfect, 

 accords with the still more imperfect example figured by

 pi. Ivii. figs. 2, 3. 



31353. The proximal half of the right humerus. 



31353. A slightly imperfect right humerus of rather smaller dimen-

31422. A right ulna, imperfect proximally, probably referable to this 

 species. 



31426. A left ulna, wanting the proximal portion, of the same type

 being 0,085 and that of the tarso-metatarsus 0,045. 

 Hab. Europe (France). 



31521-24. Four slightly imperfect specimens of the metacarpus; 



from the Lower Miocene (Upper Oligocene) of Allier. 



These specimens resemble the one figured by Milne-Edwards 



in his ' Oiseaux Fossiles de la France,' pi. Ivi. figs. 5, 6.
