88 ANIMALS OF THE PAST 
my friend Dr. Stejneger tells me that, while 
hundreds of dead sea-fowl are cast on the 
shores of the Commander Islands, it is a rare 
thing to find one after daylight, as the bodies 
are devoured by the Arctic foxes that prowl 
about the shores at night. But, again, as in 
the Miocene of Southern France and in the 
Pliocene of Oregon, remains of birds are fairly 
numerous, showing that, under proper con- 
ditions, their bones are preserved for future 
reference, so that we may hope some day to | 
come upon specimens that will enable us to 
round out the history of bird life in the past.

The first discovered specimen of Archeopteryx, Arche- 
opteryx macrura, is in the British Museum, the second 
more complete example is in the Royal Museum of Nat- 
ural History, Berlin. The largest collection of toothed 
birds, including the types of Hesperornis, Ichthyornis 
and others, is m the Yale University Museum, at New 
Haven. The United States National Museum at Wash- 
ington has a fine mounted skeleton of Hesperornis, and 
the State University of Kansas, at Lawrence, has the ex- 
ample showing the impressions of feathers.
