artery ; the deep tendinal groove on the outer side of the bone, and this 

 species has a distinctive pit anteriorly at the base of the middle 

 trochlear process, the apex of which latter, posteriorly, is gradually 

 turned toward the outer side. This character is especially well 

 marked in P. carbo, anteriorly; the shaft is smooth and fiat, while 

 posteriorly it is much marked up by the tendinal grooves, and, on the 

 whole, considerably compressed antero-posteriorly. 



This Cormorant was very much smaller than P. macropus Cope, 

 and, judging from the carpo-metacarpus of P. idahensis (PI. VI, Fig. 

 44), it was smaller than that species. 



Phalacrocorax mediterraneus^ sp. nov. 



(Plate XV, Fig. 138.) 



Holotype. Cat. No. 943, Peabody Museum, Yale University. Gerry's Ranch, 

 North Colorado. Oligocene (White River). G. B. Grinnell, collector. 



Established on the proximal part of a fossil carpo-metacarpus from 

 the right pectoral limb. 



This was a Cormorant of large size equal to Phalacrocorax perspi- 

 cillatus. 



Although we have but a part of the bone here, it proves to be a part 

 which can not be mistaken as having belonged to any other kind of a 

 bird, so distinctive is the proximal part of the carpo-metacarpus in 

 a true Cormorant. 



Phasianus americanus sp. nov. 



(Plate XII, Figs. 83, 84.) 



Holotype. Cat. No. 956, Peabody Museum, Yale University. Parilina Creek, 

 Oregon. Six miles from its junction with Beaver Creek, and 40 miles S. W. from 

 Camp Watson. Upper Oligocene (Middle John Day). L. S. Davis, collector. 



There are two imperfect bones in this lot, namely the distal 

 extremity of a left tarso-metatarsus, and a pedal phalange, which 

 probably belonged to the same individual. The tarso-metatarsus 

 evidently belonged to a pheasant, and to a species somewhat larger 

 than Phasianus aljhildx,' and I here propose the name for it of 

 Phasianus americanus. It is an interesting fact that ages after the 

 true pheasants of this country became extinct, the imported ones 



"• Generic name = Latin, phalacrocorax, a cormorant. Sp. name = Latin, 

 medius, middle, and terra, land,- — that is referring to this species having had its 

 range in the central part of the North American Continent, in so far as at present 

 known.
