question is naturally a most interesting one.

Herr August von Pelzeln has been good enough to forward 
us a copy of his work on the Ornithology of the Voyage of the 
c Novara* round the world in the years 1857-59 *. The principal 
portion of the ornithological objects were collected by Herr 
Zelebor, who was among the men of science forming the Expe¬ 
dition ; but various and not inconsiderable additions were also 
made by other naturalists, among whose names we are gratified 
to see Mr. Swinhoe*s. We are left to infer the route taken by 
the c Novara;* but this appears to have been from Europe to Rio 
de Janeiro, touching at Madeira, thence to the Cape of Good Hope, 
and so onto St. Paul*s Island; after that to Ceylon, the Nicobar

Islands, Malay archipelago, and the Coast of China; then the 
Marian and Caroline Islands (Puynipet) to Australia and New 
Zealand; then across the Pacific, visiting the Society Islands, Pit¬ 
cairn, Mitchell*s Islands, and Juan Fernandez, to Valparaiso, and 
so home by way of Cape Horn. In the introduction, Herr von 
Pelzeln suggests the propriety of forming the ocean south of the 
tropic of Capricorn into a new zoological region, in addition to 
those proposed in the well-known geographical classification of 
Mr. P. L. Sclater. The arguments adduced, however, in favour 
of this course are not, we think, sufficiently convincing, being- 
founded chiefly on the fact of the very peculiar genus Chionis, 
and the yellow-hooded species of Eudyptes being confined within 
those limits. The author*s remarks on the variations in the 
plumage of many members of the Falconidce , and on the geogra¬ 
phical distribution of Accipitres , deserve attention. As species 
now for the first time publicly described, we have Micrastur 
macrorhynchus from Brazil—a discovery of Natterer*s ! (on 
which Herr von Pelzeln takes occasion to describe minutely the 
allied species M. concentricus and M. gilvicollis ), Gerygone auck-
