which is larger and quite white below. Of the first Darwin says ^ 

 that it " never leaves the quiet inland sounds. When disturbed 

 it dives to a distance, and, on coming to the surface, with the 

 same movement takes flight. After flying by the rapid movement 

 of its short wings for a space in a straight line, it drops as if 

 struck dead, and dives again." The egg is deposited in a small 

 burrow ; the note is a cackle or moan. 



Fossil remains are recorded from the Pacific, Australia, and 

 Xew Zealand, which are referred to the genera Fuffinus, Ossifraga, 

 and Biomedea, and probably belong to existing species ; Fuffinus 

 conradii is from the American Pliocene, P. eyermcmi from 

 Tavolara, off Sardinia ; but a much more remarkable fact is the 

 discovery in the Suffolk Eed Crag of portions of a distinct form, 

 named Biomedea anglica by i\Ir. Lydekker.^
