stork, crane, pheasant, California peacock, a p"\v condor and teratornis 

 merriami. That peacocks shovM be found here, is remarkable since 

 this bird is known only in the old world. There are doubtless several 

 species of these, as the material at hand shows a decided difference 

 in structure. The teratornis named by Mr. Miller is the very largest 

 bird thus far determined. It was larger than any of our present 

 condors and was a large sailing bird with a strongly compressed, 

 hooked beak and very deep.

The birds evidently survived the ordeal of extinction suffered 

 by the mammals, since so many of the forms found are yet living. 

 This is what might be expected, since the birds are more readily capa- 

 ble of migration, and the amount of their food required is com-

 of the flesh eaters, which is to be expected, since so many chances 

 were offered to feed upon the dead carcasses of the mammals, caught
