80 THE ZOOLOGIST. 
Nares’ ‘Voyage’ (p. 210), and in ‘The Ibis’ for 1877 (p. 406). 
Again, the Ruff, Machetes pugnaz, which Mr. Seebohm tells us 
(p. 131) is confined to the Eastern Hemisphere, is certainly 
found in the New World. We learn from Dr. Elliott Coues that 
it is occasionally killed on the coast of New England and the 
Middle States, and it has been met with on Long Island (Baird), 
Massachussets (Brewster, Amer. Nat., vi., p. 806), Ohio (Bull. 
Nuttall Orn. Club, ii., p. 83), as well as in Spanish Guiana (von 
Pelzeln, ‘ Ibis,’ 1875, p. 332). 
The impression entertained by Mr. Seebohm (p. 127), to the 
effect that the Blue-throated Warbler, Cyanecula suecica, has 
only twice been met with in the British Islands, would have been 
speedily removed had he consulted the first volume of the fourth 
edition of Yarrell’s ‘ British Birds,’ or pp. 103, 104 of the ‘ Hand- 
book of British Birds,’ where more than a dozen instances of its 
capture in England are recorded. 
These and a few other similar errors which we have noted are 
easily rectified, and may well be passed over lightly when we con- 
sider the additions to ornithological science which Mr. Seebohm 
and his fellow-traveller have been the means of making. We 
should like to quote some of their field-notes on the occurrence 
in Siberia for the first time, so far as ascertained, of the Eastern 
Stonechat, Pratincola maura, on the habits of the Pine Grosbeak 
(p. 119), on the distinction between the sexes of the Waxwing 
(p. 145), and on the habit of perching exhibited by Snipe and 
other waders, and gulls (p. 147), a habit which the authors believe 
is due to the flooding of the great tracts of country by the annual 
overflow of rivers at the time of migration. 
But on these and other points equally interesting we must 
refer our readers to the book itself. Messrs. Seebohm and 
Harvie-Brown are to be congratulated on the accomplishment of 
their arduous journey, and upon the valuable results obtained by 
their exploration of a practically unknown country. 
The nice engravings with which the book is illustrated bring 
vividly before the reader, some of the more remarkable features of 
Siberian scenery and characteristic forms of Siberian animal life.
