PROCELLARIA PELAGICA. 



tail-coverts white, the longer coverts broadly tipped with black ; under-surface of body 

 rather more smoky-brown than the back, with a patch of white on each side of the 

 lower flanks, adjoining the white patch on the upper-surface ; under tail-coverts smoky 

 brown like the abdomen ; under wing-coverts sooty-black, the greater series white 

 at the ends, forming a patch ; axillaries also sooty-black, the longer ones with broad 

 white ends ; bill and feet black ; iris hazel. Total length, 6.5 inches ; culmen, 0.45 ; 

 wing, 4.7 ; tail, 2.1 ; tarsus, 0.95 ; middle toe and claw, 0.8. 



Adult female. Similar to the male. Total length about 6.19 inches; wing, 4.85; 

 tail, 2.2 ; tarsus, 0.9 ; middle toe and claw, 0.8. 



Young. At first covered with long down of a sooty ash-colour, making the bird 

 look like a long-haired mouse, as no bill or wings are visible. When the down is shed, 

 the plumage of the young bird is exactly similar to that of the adult, with the exception 

 that the greater wing-coverts have a distinct, if narrow, margin of white. The 

 scapulars and black tips of the upper tail-coverts also have nearly obsolete white 

 fringes. These characters are clearly shown in a specimen from Syre, Sutherlandshire, 

 presented to the British Museum by Mr. H. St. George Peacock. It was obtained on 

 the 19th October, 1900, and is full-grown, but with some remains of the nestling down 

 on the abdomen. 



The specimen figured is in our own collection, and was obtained in the Orkneys 

 by the late John Dunn. The male described is in the Seebohm Collection, and was 

 procured on the Lincolnshire coast on the 10th November. The female was obtained 

 in the North Atlantic during the voyage of the " Herald."
