wings, and the chin and throat are white; bill pale at the base,’ especially 
at the lower mandible, rest dark horn; legs black; outer and middle toe of 
one foot pied; claw of outer toe white; claw of the middle toe of the other 
foot also white. The other and still younger bird, killed on the 2nd of 
June, has also some of the feathers at the base of the upper mandible black 
and some white; forehead white, with a black patch in the centre; chin 
white; some of the wing-coverts white, some partly white and partly black ; 
the greater number, however, are of their proper colour; of the quill-feathers, 
which are only partly grown out, four on one wing are nearly white, on the 
other the first quill is nearly all black, except a patch of white near the tip 
of the inner web; shaft black; the shafts of all the white feathers are white ; 
the pen part of the quills, which were still soft and full of matter, were in 
the white feathers white, and in the black feathers dull lead, showing the 
colour of the matter contained in them; bill, upper mandible pale yellow at 
the base, darkish towards the tip, ridge of culmen whitish horn—lower 
mandible pale yellow at base, whitish horn towards the tip; legs black ; 
outer toe of one foot black, all the others slightly pied, claws all white; on 
the other foot the toes are all more or less pied, the middle claw is black, 
the rest white; the irides in this bird were pale, nearly white. Had not 
these two rooks been killed I should have been curious to see whether they 
assumed their usual plumage after the first moult, and for this reason 
should certainly not have shot them myself—at all events, not till after at 
least three moults: not that I care about preserving these pied and albino 
varieties,—on the contrary, I do not like to see them about,—but because 
I have a strong notion that in many cases they assume their normal 
plumage after a time.—Cecil Smith ; Bishop's Lydeard, near Taunton. 
Greenland Shark off the Suffolk Coast.—A very fine Greenland shark 
(Squalus borealis) is now exhibiting in this city: it was taken off Kessing- 
land, Suffolk, on the 28th of February last: it is, I believe, a male, and 
measures twelve feet six inches in length and seven feet in girth. It is 
advertised as a ‘‘ white shark.”—Thomas Southwell ; March 12, 1875.
