he describes a new species (of Pceocephalus ), under the name 
Psittacus versteri, from Guinea, allied to P. senegalus. The plate 
of the new Pigeons of the genus Ptilopus referred to by Prof. 
Schlegel in his letter to us ( antea , p. 120), is given in the first 
Number of this work, but not the descriptions.

Professor Sundevall has again contributed a valuable work to 
the Transactions of the Royal Academy of Science at Stockholm*, 
entitled “ Ett forsfik att bestamma de af Aristoteles omtalade 
Djurarterna,” Stockholm, 1862. The volume is a careful com¬ 
pendium of the Aristotelian natural history, compiled on a 
system which has not hitherto, so far as we are aware, been 
attempted in any language, and which enables the student at 
once to ascertain and gauge the amount of knowledge attained 
by the great master, on each species which came under his ob¬ 
servation. The first portion of the work consists of a life of 
Aristotle, with especial reference to his opportunities for obtain¬ 
ing natural information, and a careful and lucid summary of his 
system, compared, step by step, with the conclusions of modern 
science, and shows how the grand outline of the map of nature, 
which it needed Linnseus and Cuvier to fill up, was traced with 
tolerable exactness by the mighty Greek. His divisions evaipa 
and avatpa correspond with those of Vertebrata and Inverte- 
brata, and although the subdivision of the former into ooro/ca 
and koTOKa is somewhat confused with the parallel separation 
into airrepa and 'irrepwra , it yet is marvellous how, in the far 
more recondite Invertebrate kingdom, Aristotle had a glimpse 
of the grand distinctions between Crustaceans (paXa/coo-rpa/ca ), 
Cephalopods (paXa/aa), Molluscs ( 6(TTpa/c68eppa) } and Insects 
( evropa ). 
Prof. Sundevall has certainly elucidated the systematic con¬ 
ceptions of Aristotle with greater clearness than his German pre¬ 
decessors in the same field, J. B. Meyer Aristoteles Thierkunde*), 
and Lenz ( f Zoologie der alten Griechen und Romer - ’). The sub¬ 
sequent chapters are devoted to a summary of the account given 
by Aristotle of each species, arranged in accordance with the
