CINEREOUS SHEARWATER. 
From Sir. Gould’s figures, this bird would seem to 
vary in the dark aud under-parts in a manner similar 
to some of the genus Lestris; the whole appearance 
of Mr. Yarrell’a wood-cuts reminds us of the jagers. 
In the darker bird, the “ head and neck all round, 
and the back dark clove-brown ; scapulars and ter- 
tials 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; whole length of the 
bird seventeen inches and a quarter.”* 
In the lighter coloured bird the “head and occi- 
put dark ash-grey ; back of the neck almost white; 
both wing coverts and tertials ash-grey; all the 
margins greyish white; primaries and tail-feathers 
blackish brown ; chin, sides, and front of the neck, 
the breast and sides of the body, white ; lower 
belly, vent, and under tail coverts, varied with dull 
white and ash-brown ; legs, toes, and their mem- 
branes, brownish yellow; the whole length, eighteen 
inches. 
In Mr. Selby’s specimen, the “ head, back part of 
the neck, and upper plumage, blackish brown, with 
the margins and tips of the feathers of the scapulars 
lighter; throat, lower part of the neck, and whole 
of the under plumage, deep ash-grey, with a tinge 
of brocoli-brown.”
