LEVANTINE SHEARWATER. 
Case 230. 
The darker plumaged bird to the right belongs 
to this well defined race or species, which is an 
extremely rare visitor to our seas. 
In his ‘Rough Notes,” Booth mentions that he 
got this bird on August 19th, 1874, in the Firth of 
Forth. It was a calm day, and numbers of Kitti- 
wakes and Guillemots were scattered over the sea in 
flocks as far as the eye could reach, with small parties 
of Shearwaters dispersed amongst them, swimming 
from one spot to another, occasionally skimming the 
water with their beaks, and sometimes allowing the 
boat to come within 20 or 30 yards, He secured a 
few specimens that morning with perfectly white 
breasts. Also this one in which he observed that 
the plumage of the throat, breast and belly was of a 
uniform dusky grey, It will be observed that the 
plumage of the back is also duller and the beak 
longer than in the true Manx Shearwater. 
PALLAS’S SAND-GROUSE. 
Case 308. 
These wanderers from the Central Asian steppes 
occasionally migrate westward in considerable num- 
bers, and, though excessively rare in Britain at other 
times, are then obtained somewhat commonly. Such 
an immigration happened in 1888, and some of the 
visitors survived the winter and even succeeded in 
nesting the following spring.
