176 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Sciences and in the British Museum of Natural History. The Princeton 

 Expeditions to Patagonia did not obtain specimens of the Sooty Alba- 

 trosses, but Mr. Hatcher states that he observed "black albatrosses" at 

 sea not far distant from the eastern entrance to the Straits of Magellan. 



Moseley in "Notes by A Naturalist on the 'Challenger,'" p. 180 

 (1879), writes : 



" High up, at about 500 feet elevation, were some four or five Sooty 

 Albatrosses [Diomedea fn/iginosn, the Piew or Pio of sealers), soaring 

 about the tops of the cliffs snd probably nesting there. This bird is con- 

 tinually to be seen about cliffs and higher mountain slopes, and seems 

 never to nest low down like the Molly mauk and Goney." 



"Nests on rocky shelves or in caves in the faces of lofty cliffs where 

 the birds build a conical mound, seven or eight inches high, hollowed 

 into a cup at the top and lined rudely with grass. Egg is single, broadly 

 ovoidal, generally white, marked by a collection of specks about the 

 larger end, somewhat like the adventitious stains on the eggs of Z). exu- 

 lans, but, as well as we can judge, less superficial. The shell is compact 

 in structure, rather thin for its size, and superficially smooth to the touch. 

 Under the lens, it is seen to be marked by minute pits and linear depres- 

 sions, being thus decidedly different, both to the eye and to the touch, 

 from those oi D. exttlans." (Natural History of Kerguelen Island, J. H.
