This publication treats of the following matters : — the Poverty 
of the fauna of Siberia and its similarity to and accordanee with 
that of Europe (p. 785), the Siberian Vertebrates noticed by the 
author in his travels (p. 789), the extent of ideas as to species 
(p. 790), the variation of Siberian animals (p. 798), the unity of 
the geographical range of eacli species (p. 822), the foundations 
for a history of the distribution of Siberian animals, including 
Extinction (p. 829) and the preservation of animals recpiiring it 
(p. 875), the Hyperboreal Fauna (p. 910) and Birds especially 
(pp. 964-969), the Animals of Circumboreal Siberia (p. 976), 
Birds of the Circumboreal Tundras (])p. 987, 988) and Forests 
(pp. 1007-1009), Alpine animals compared with those of the 
High North (p. 1009), the birds especially and the difficulty of 
deciding to which category certain species belong (pp. 1015- 
1017), Polar and Boreal animals (p. 1017), Paloeoboreal animals 
(p. 1026), Advance of the circuit of Distribution (p. 1052), with a 
Retrospect of the whole subject (p. 1066), concluded by soine 
additions (p. 1079). 
It is quite impossible for us here to indicate more particularly 
the very varied contents of this treatise, which seems to be ad- 
mirably executed. Countless facts are brought together from 
all kinds of sources ; but it may be observed that they are not 
always taken from the newest works on the subject. 
Paijkull, C. W. a Summer in Iceland. Translated by M. 
R. Barnard. London : 1868. 8vo, pp. 364. 
The original, published in Swedish, contains nothing ornitho- 
logical except a moderate woodcut of Alca imptnnis. The trans- 
lator adds a footnote (p. 8) containing an exceedingly doubtful 
assertion, and an Appendix,^^ including, among other things, a 
List of Birds found in Iceland (pp. 353, 354) . This is transcribed 
from the list given by Dr. Robert in 1851 (Voyage en Islande 
et au Greenland. Zoologie et Medecine, pp. 161-166), which 
is founded upon Gliemann^s (Geogr. Besclir. v. Islande. Altona : 
1824, p. 150-170), and is utterly worthless ; but the translator 
only is to blame, \_Cf. Ibis, 1869, pp. Ill, 112.]
