Fossil Birds in the Marsh Collection of Yale University 49 



132. It is of a pale clay color or drab. There is with it the distal end 

 of another pedal phalanx (fossil), which would appear to be too small 

 for a foot of this e.xtinct owl. 



Cat. No. 884, Peabody Museum, Yale University. Locality unrecorded. 

 Eocene (Bridger). LaMothe and Chew, collectors. 



Basal phalanx of hallux (fossil, black) of an adult individual of 

 Minerva antiqtia, from the opposite foot to the one shown in Figure 

 133 of Plate XV, with which it agrees exactly in all particulars. 



In this lot there is also a very small cervical vertebra (fossil, adult) 

 from some bird not larger than a Barn Swallow {Hirundo erythro- 

 gastra). It would be useless to endeavor to identify it. 



Cat. No. 892, Peabody Museum, Yale University. Henry's Fork, Wyoming. 

 Eocene (Bridger). C. G. Knox, collector. 



This appears to be an imperfect fossil basal hallucial phalanx of 

 a specimen of Minerva antiqua, and I believe it is, as it agrees prac- 

 tically with Figure 154 J of Plate XV. 



Cat. No. 857, Peabody Museum, Yale University. Black Fork, Wyoming. 

 Eocene (Bridger). R. E. Son, collector. 



Eleven fossil fragments of bones, some of which are mammalian 

 or other vertebrates (caudal vertebrae); while there is with them in 

 the lot a claw, which in life belonged to a specimen of Minerva antiqua. 

 It is from the third toe and can be readily recognized, although the 

 characteristic process is broken off, as is the distal moiety of the bone. 

 Originally, it was of the same size as the specimen shown in Figure 149 

 of Plate XV. 



Cat. No. 846, Peabody Museum, Yale University. Henry's Fork, Wyoming. 

 Eocene (Bridger). O. C. Marsh, collector. 



Five fossil fragments of bones from an adult specimen of Minerva 

 antiqua. (1) Basal portion of the ungual phalanx of one of the 

 anterior digits of pes. (2) A basal hallucial phalanx of a foot (nearly 

 perfect). (3) Two other imperfect phalanges, but interesting from 

 the fact that each possesses a conspicuous mesial process, situated 

 posteriorly on the plantar aspect of the articular facet of the bone. 

 This process is present in the corresponding pedal phalanges of 

 Nyctea and in probably other Strigida% while I do not find it in any 

 eagles.
