Suborder XX. ODONTOLC^. 



Tcetli implanted in a groove ; vertebral centra sadclle-shaped 

 carina of stornnm (when known) aborted. 



Family ENALIORNITHID^. 



Very imperfectly known, and provisionally ]>laced here on 

 account of the resemblance of the femur and tarso-metatarsus to 

 the corresponding bones of Coh/mbits and Ifexperomis. 



Genus ENALIORNIS, Seeley '. 



Syu. Pdlcporohjmhts, Seeley^. 

 Peluffornis, Seeley ■'. 



Founded upon isolated fragmentary bones, which may or may 

 not all belong to one genus, and neither of which is definitely 

 described as the type. 



The tarso-metatarsus probably referable to this genus is 

 characterized by the lateral compression of its distal extremity, 

 which doubtless indicates swimming habits. The second trochlea 

 is much shorter than either of the others and greatly reflected. 

 The fourth trochlea is slightly wider and longer than the third ; a 

 feature in -which this bone approximates to Hesperomis. The 

 general contour of the tarso-metatarsus is very similar to that of 

 Baptornis, Marsh \ from the North- American Cretaceous ; but in 

 the latter the reflection of the second trochlea is less marked, and 

 the length of the fourth trochlea does not exceed that of the third. 

 It is probable that the tarso-metatarsus of Enaliornis, like that of 

 Baptornis, had no talon (hypotarsus).
