from the Orient are now thriving in numbers in the same locality- 

 This species was about one-third larger than Phasianus colchius, to 

 which species, I take it, it was otherwise pretty closely related. 



BIRD (Not sufficientlj' characteristic for exact determination). 

 (Plate V, Fig. 29 b.) 



Cat. No. 912, Peabody Museum, Yale University. Colorado. [Probably 

 Oligocene. Lull.] 



Consists of the distal end and a good part of the shaft of the left 

 tibio-tarsus, in a perfect state of preservation, and but very slightly 

 chipped. It was from an adult individual, and belonged to some bird 

 wherein the osseous bridge on the anterior aspect, spanning the 

 tendinal groove below, is absent. 



This is the case in a large number of avian species, belonging to 

 entirely different groups, as, for example, Owls or the Psittaci. The 

 bone here described belonged to some form about the size of a Barred 

 Owl {Strix V. varia), or a somewhat smaller species, or to any of the 

 larger Macaws (Ara); the condyles, however, are entirely different 

 from what we find to be their form in existing Owls, while, on the 

 other hand, it does not seem to be any nearer the Psittaci. To define 

 what kind of a bird this belonged to, we should have additional mate- 

 rial, and until this comes to hand, it is best to leave it as being an 

 indetermined species. 



BIRD (indetermined).

Cat. No. 958, Peabody Museum, Yale University. John Day River, Oregon. 

 [Probably Oligocene. Lull]. S. H. Snook, collector. 



Lot consists of over thirty bits of fossilized bones, apparently all 

 from one and the same indi\ddual. Many of them are covered for 

 the most part with a greenish gray, flinty matrix; other pieces are free 

 from it. There is a distal end of a left ulna (Fig. 107) ; the proximal 

 end of a right carpo-metacarpus (Fig. 108), half embedded in the 

 matrix; a fragment of the upper third of the indicial shaft of a right 

 carpo-metacarpus, also embedded in its matrix (Fig. 109), and the 

 middle and inner trochlea, with proximal ends of the basal phalanges 

 (articulating wdth them) of the right tarso-metatarsus, embedded on 

 the plantar aspect in the matrix (Fig. 116). 



These bones belonged to some quite typical tetraonine of about the 

 size of Centrocercus iiro phasianus; but they are altogether too frag-
