beautiful adult male (in full autumn plumage) of (3) Turdus 
atrigularis, which is the ninth Italian specimen preserved in 
our museums; and (4) three hybrids between the Common 
Pochard and the Ferruginous Duck (well known as Fuligula 
homeyeri). They are all adult males, and were captured in 
the large marshes at the mouths of the River Po, where 
Pochards and the allied diving-ducks are extremely plentiful 
in winter-time. 
Yours &c.,

Sirs,—In the December number of Orn. Mon. (xiv. 1906, 
no. 12, p. 190) Dr. Reichenow describes as new a Crane from 
North-eastern Siberia (Bay of Anadyr) under the name of 
“* Grus niediecki.””, The single specimen of the bird is said to 
be very similar to G. canadensis, but differs in being much 
smaller (wing 430 mm., tail 150 mm., bill 88 mm., tarsus 
165 mm.) and in having the cheeks and throat whitish grey. 
In working over my Siberian collections I carefully com- 
pared in the Academical Museum of St. Petersburg three 
specimens of Cranes from Anadyr collected by Dr. Grinewtzki, 
with three from Western America (a male from Northern 
California, 23 Feb., a female from tke Mission of St. Raphael, 
N. Calif., 10 Jan., and a young bird from Herba Buena, San 
Francisco Bay, Nov.), all collected by Vosnessensky. 
I find that all these birds are practically identical, being 
light grey with dark slaty primaries, clear lavender-grey 
neck, whitish cheeks and throat. The only difference in 
plumage of the Anadyr birds is that they are somewhat more 
stained with dirty ochreous or bay colour, but this is usually 
the case in summer specimens of all grey Cranes. 
I may add that the whitish throat and cheeks of American 
specimens of Grus canadensis were mentioned as long ago as 
1884 by Baird, Brewer, and Ridgway (Water Birds of N. A. 
i. p. 408), as also the frequent rusty wash of its general 
grey colouring.
