GREATER SHEARWATER. 629 



seen, none have exceeded eighteen inches in length, and 

 the dark-coloured specimens, which may be females, or 

 young birds, are not quite so much. That our new bird is 

 not the P. fuliginosus of Kuhl, I feel certain, from having 

 obtained a specimen of this bird, which is not only two 

 inches shorter in its whole length than our new bird, but 

 is also a true Procellaria, having the short, strong, 

 hooked, and cutting beak, like that of our Fulmar last 

 described. 



In the dark-coloured bird from which our upper figure 

 was taken, the bill is dark brown, the base of the under 

 mandible lighter brown ; irides dark brown ; head and 

 neck all round and the back dark clove-brown ; scapulars 

 and tertials the same, but with lighter-coloured margins ; 

 wing-coverts, primaries, and tail-feathers blackish-brown ; 

 breast and belly greyish hair-brown, each feather much 

 darker in colour on the margin than over the centre ; legs 

 brown on the outer surface, but pale wood-brown on the 

 inner; toes and their membranes yellowish-brown. The 

 whole length of the bird seventeen inches and one quarter ; 

 wing, from the anterior bend, twelve inches and three 

 quarters ; whole length of the bill one inch and three- 

 quarters; of the tubular portion half an inch; of the 

 tarsus two inches ; of the middle toe, including the claw, 

 two inches and five-eighths. 



In the bird from which the lower figure in our woodcut 

 was taken the bill is dark brown, under mandible lighter 

 brown at the base ; irides dark brown ; head and occiput 

 dark ash-grey ; back of the neck almost white ; back, 

 wing-coverts, and tertials ash-grey ; all the margins grey- 

 ish-white; primaries and tail-feathers blackish-brown ; chin, 

 sides, and front of neck, the breast, and sides of the body 

 white ; lower belly, vent, and under tail-coverts varied
