MAMMALIA. 
A complete account of the Mammals of Scandinavia, with remarks on 
classification, and a considerable amount of anatomical detail ; notes on 
some of the more important exotic and fossil forms are also introduced. 
92 native species are recognized, of which 23 are Cetaceans.

Tertiary Times. P. Conn. Ac. 1874. 
All the earlier animals were inferior in cerebral volume to their suc- 
cessors, Thus the brain was proportionately smaller in the Eocene 
Tinoceras and Uintatherium than in the Miocene Brontotherium^ which 
again wag surpassed by the Pliocene Mastodon. The same facts are 
observed in the fossil Equidce. [Not seen by the Recorder ; cf. J. Zool.

This beautiful work, of which the earlier parts have been akeady 
noticed [c/*. Zool. Rec. v. p. 3, vi. p. 2, viii. p. 2, and ix. p. 2], has been 
brought to a conclusion by the completion of A. Milne-Edwards^ memoir 
on the Mammals of Thibet. Many rare animals are figured for the first 
time, and 3 new species are described.

The Pig is here taken as a type of the class, and the development of i 
its cranium is carefully worked out. Of the auditory ossicles the stapes 
is developed from the auditory capsule, the malleus from the mandibular 
arch, and the incus from the hyoidean arch.

Anatomy in the Museum of Guy’s Hospital. London : 1874. 8vo, 
pp. 294. 
The characters of the various classes and orders are shortly stated, 
and attention is called to the principal structural modifications of each 
form, so that the catalogue will form a useful handbook to students who 
have access to the collection.

The author’s object is to give correct figures and descriptions of the 
Cetaceans and Pinnipeds of the American Pacific Coast, with full details 
of their habits as observed by himself. The species figured, many of 
them for the first time, will be referred to in the special part. The 
plates, from the author’s own sketches, are carefully executed, and the 
account of the habits and chase of the animals is full of interest. No
