36 PROCELLARIID^. 



not find more than one egg in each nest. I secured several 

 birds and eggs, and kept some of the former alive. It is 

 curious to watch them crawling along the ground ; for they 

 cannot fly unless they get to the edge of a rock ; they 

 waddle along on their feet, and, when they come to a steep 

 place, use the sharp-pointed hook of their beaks to draw 

 themselves up with. They seem to dislike the light, and 

 hide themselves under a rock or crawl into a hole as soon 

 as possible ; I never saw one of this species flying about in 

 the daytime, though some of the smaller ones are common 

 enough," 



The" egg is pure white, the average measurements being 

 1-75 by 1-25 in. 



In the Leiden Museum there is a specimen of this Petrel 

 received from the Moravian missionaries, and said to come 

 from Greenland, but the late Prof. Pieinhardt informed Mr. 

 Freke (Zool. 1881, p. 378) that he thinks it may have 

 come from Labrador. With this exception, its range seems 

 to be very limited ; there is, however, a closely-allied species, 

 B. macgillivrayi, found in the vicinity of the Fiji Islands. 



In the adult bird the bill is black ; the irides deep brown ; 

 the whole of the plumage almost uniform brownish-black, 

 rather paler on the edges of the great wing-coverts ; tail 

 much graduated and cuneate ; legs and toes dark reddish- 

 brown, the interdigital membranes dark brown. The whole 

 length, from the point of the beak to the end of the tail, 

 ten inches and a half; wing, from the anterior bend to the 

 end of the longest quill-feather, eight inches ; bill three- 

 quarters of an inch in length from the base ; tarsus and 

 middle too, including the claw, one inch and one-sixteenth. 



The nestling is said to be covered with a sooty-brown 

 down.
