NOTICES OF NEW BOOKS. 77 
“They would fling themselves up into the air almost like a shuttle- 
cock, singing all the time a low and melodious warble, not unlike that of a 
Shore Lark, or perhaps still more like that of the Lapland Bunting, and 
they would immediately descend in a spiral curve, with wings and tail 
expanded, and finish their song on a rock.” 
On the outskirts of the town a few small “parties” of Yellow- 
hammers were met with, and occasionally their familiar song was 
heard. They were, however, rare; and as none were seen further 
north it is presumed that Ust-Zylma is about the extreme 
northern limit of their summer range. 
DOING ROBINSON CRUSOE AT DVOINIK. 
The forests were remarkably silent. Often there was not a 
bird to be seen for miles; and on the whole the stay made at 
Ust-Zylma was by no means encouraging. After eight days’ 
work our travellers had identified only the following species :— 
Hooded Crow, Raven, Magpie, Tree Sparrow, Snow Bunting, 
Mealy Redpoll, Yellowhammer, Capercaillie, and Hazel Grouse. 
The first nest found was that of a Siberian Jay on the 28th April. 
It contained four eggs. 
In the valley of the Petchora both Linota linaria (Linn.) and 
L. exilipes (Coues) were found, and from an examination of 
specimens Mr. Seebohm came to the conclusion that the latter is 
nothing but the fully adult winter plumage of the former.
