THE VOYAGE OF H.M.S. CHALLENGER. 



lanicus (PL XXVIII. fig. 1) the well-marked double black band on the breast renders the 

 species at once recognisable. 



Another quite distinct species that Dr Coues has united to Spheniscus demersus is 

 Spheniscus humboldti, Meyen, of the coasts of Chili and Peru. This specimen has only 

 one black band like Spheniscus demersus ; but this band is much broader, while the 

 white frontal band is much narrower. It is also considerably smaller in dimensions.

Mr Murray sends me the following notes on Spheniscus magellanicus : — 

 " We frequently saw these birds in the eastern parts of the Straits of Magellan, but 

 always in the water. At the Falklands we found several rookeries. These birds burrow 

 into both sandy and peaty banks. ' Sam,' our Newfoundland dog, dug out some of 

 these nests fully 8 feet into the sand hills. 



" In their stomachs were fish-bones, cuttlefish beaks, and pebbles. It is quite astonish- 

 ing the number and size of the stones, shells, and pebbles which were noticed lying 

 about the mouth of the burrows.
