FULMARUS RODGERSI. 



about 18.5 inches ; culmen, 1.45 ; wing, 11.3 ; tail, 5.2 ; tarsus, 2.0 ; middle toe 

 and claw, 2.6. 



In two of the specimens examined by me the bill is orange or dusky yellow, with 

 a black border on the forehead, and the anterior margin of the nasal tube is also black, 

 as well as the space between it and the unguis. One of these birds has some grey on the 

 crown, which may be the sign of immaturity, as it is accompanied by a certain amount 

 of grey on the under-parts. 



No dark form of the species has yet been discovered. 



The specimen figured is a male procured by Mr. H. W. Elliott on St. George's Island, 

 while that described is from the North Pacific, obtained by Captain Kellett and 

 Lieutenant Wood ; both are now in the British Museum.
