PLATE XIV 



[All the Figures on this Plate are of natural size, being reproductions of photographs 

 made direct from the specimens by the author] 



Fig. 111. Fossil vertebra of a bird ? (indetermined). This specimen was 

 associated with the one shown in Figure 112 of this Plate, but it does not appear to 

 have belonged to it. (John Day; Oligocene ??). 



Fig. 112. Outer aspect of the left tibio-tarsus of Larus pristinus, sp. nov. 

 (extinct). (Willow Creek, Oregon.) (John Day; Oligocene ?? ). See Figure 111. 



Fig. 113. Palmar aspect of the right Intmcrus of Phalacrocorax carbo. No. 

 18851, Coll. U. S. Nat. Mus., for comparison with the corresponding bone of 

 Phalacrocorax marinavis, sp. nov. (Figure 114.) 



Fig. 114. Palmar aspect of the distal half of the right Innucriis oi Pltalacro- 

 corax marinavis, sp. nov. 



Fig. 115. Anconal aspect of the left humerus of Phalacrocorax carbo. No. 

 18851, Coll. U. S. Nat. Mus., for comparison with the corresponding bone of Phala- 

 crocorax marinavis, sp. nov. (Figure 116.) 



Fig. 116. Anconal aspect of the distal half of the left humerus of Phalacro- 

 corax marinavis, sp. nov. 



Fig. 117. Ventral aspect of an ultimate cervical vertebra;, and one which 

 probably belonged to Phalacrocorax marinavis, sp. nov., the individual to which 

 the other bones of that extinct species belonged and which are figured on the Plate. 



Fig. 118. Palmar aspect of the right ulna of Phalacrocorax marinavis, sp. nov.; 

 radial process broken ofif. Compare with Figure 119. 



Fig. 119. Palmar aspect of right ulna of Phalacrocorax carbo; proximal two- 

 thirds, showing radial process. (No. 18851, Coll. U. S. Nat. Mus.) 



Fig. 120. Anterior aspect of distal moiety of the left tarso-metatarsus of 

 Phalacrocorax carbo. (No. 18851, Coll. U. S. Nat. Mus.) 



Fig. 121. Anterior aspect of right tarso-metatarsus of Phalacrocorax carbo 

 (No. 18851, CoU. U. S. Nat. Mus.) 



Fig. 122. Anterior aspect, distal two-thirds of the left tarso-metatarsus 

 (fossil) of Phalacrocorax marinavis, sp. nov. (extinct). Inner trochlea broken off 

 and lost. Compare with Figures 120 and 121. {P. carbo.) All the bones of 

 Phalacrocorax carbo on this Plate are from the skeleton of the same inchvidual, and 

 they represent a larger bird than Phalacrocorax marinavis, or the extinct species, 

 with which the\- are compared.
