Professor Marsh was correct in his surmise that the specimen col- 

 lected in New Mexico was a trochlea from a tarso-metatarsus of a 

 specimen of Cope's Diatryma gigantea; but he was in error when he 

 made the determination that it was the "Outer condyle from the tarso- 

 metatarsus left side." (See description copied from the slip above.) 

 On the contrary, it proves to be the inner trochlear process of the right 

 side. 



It was discovered in New Mexico, and it was in New Mexico that 

 Cope found his specimen of Diatryma gigantea. Personally, I know 

 nothing of the history of these discoveries, though what I do know 

 points to the fact that Marsh's collector found his specimen after 

 Professor Cope had discovered and described his find. As will be seen 

 by the literature cited above, I have already given many figures of 

 the two trochlece belonging to the type of Cope's specimen, and now 1 

 find that this specimen found by Marsh completes in every way, as 

 far as it goes, the distal extremity of the tarso-metatarsus of the speci- 

 men Cope discovered. I am of the opinion that these three trochlea 

 belonged to the right tarso-metatarsus of the same individual bird, and 

 I shall entertain this opinion until history controverts it — that is, if 

 the facts be known to anyone now living. Evidently one of Professor 

 Marsh's collectors went to the exact locality where the Cope specimens 

 were pre\dously found and there discovered the missing trochlea. 

 However, the two trochlese of Cope's type of Diatryma giganiea belong 

 to the collections of the United States National Museum, and are 

 before me at the present writing, as is likewise the trochlea which is 

 the property of Yale University. I present with this article several 

 figures of it in the plates, and in Plate IX, Figt;re 68, there is a repro- 

 duction of a photograph I made which thoroughly sustains what I 

 have set forth in the last few paragraphs.
