0. a Marsh—New Odontorniihes. 511 



Ichthyornis victor, sp. nov. 



In addition to the remains described above, the Yale Museum 

 contains a number of specimens wliich indicate a new species, 

 apparently, of the genus Ichthyornis. The best preserved of these 

 fossils consist of characteristic portions of the humerus, coracoid 

 and scapula, all parts of one skeleton. They pertain to a bird 

 somewhat larger than a pigeon, and about one-third larger 

 than Ichthyornis dispar Marsh, the type of the order Odontotor- 

 mve* The humerus has the radial crest greatly expanded, in- 

 dicating strong power of flight. The radial condyle of the dis- 

 tal end is larger than that for the ulna. The coracoid is stout, 

 and at its scapular articulation has a nearly round, deep pit, into 

 which was inserted a corresponding tubercle of the scapula, 

 forming a strong support for the humerus. Above this tuber- 

 cle, the scapula has an anterior angle, sharp and pointed. 



The remains preserved of this species have the following di- 



Greatest diameter of distal end of humerus, - 



Longitudinal extent of radial condyle, 



Diameter of shaft just above condyle,. 



Greatest diameter of coracoid at articulation with scapula; 6 

 Diameter of articular pit, - . .J^' 



Transverse diameter,. 



The known remains of this species are from the same region 

 and geological horizon as those above described.
