Tis work continues to be published by the Boston Society 
of Natural History, in numbers of about 125 pages each, of 
which four make a volume. It contains numerous papers on the 
natural history of the United States, and a knowledge of its con- 
tents is indispensable to those who would understand the pro- 
gress of Zoology in North America during the last ten years. 
Price 5 dollars a volume. 
It may be obtained by addressing the Society directly, or by 
order through Witey & Purnam, No. 6, Waterloo Place, London, 
and from the principal Booksellers in New,York, Boston, and 
Philadelphia. 
Paléontologie Universelle des Coquilles et des 
Mollusques 
_ With an Atlas, representing all known species of Fossils. 
Mollusques vivants et Fossiles, ou description de toutes les espéces 
de Coquilles et des Mollusques, classées suivant leur distribu- 
tion geologique. 
Tue : are the titles of two works which M. Alcide d’Or- 
bigny has begun to publish, the one, a general work on Palzontol- 
ogy, and the other, confined to Molluscs, both fossil and recent. 
The former will constitute eight volumes in 8vo, and be illus- 
trated by 1500 octavo plates; price of each number, contain- 
ing 20 plates and the corresponding text, 6 francs. The Jatter 
work will extend to 10 volumes in 8vo, with 300 engraved plates ; 
each number containing 5 plates and 5 leaves of text, 34 francs ; 
or 5 francs, with the recent species colored. Subscription is de- 
nae at Gide et Cie., Libraires-editeurs, rue des Petits-Augustins, 
5, Paris. 
M. d’Orbigny is desirous of obtaining specimens, and the vari- 
ous publications, by American authors, bearing upon the subjects 
of the above mentioned works, and offers in exchange his own 
publications, a catalogue of which is given on the advertising 
sheet of the last number of this Journal. The value and high 
character of these publications are too well known to require com- 
ment from us, His Paléontologie Frangaise is one of the best and 
most elegant works on this branch of science hitherto published. 
From 1826 to 1834, d’Orbigny was engaged in his travels in South 
America, and in that period traversed the continent from Patago- 
nia to the equator, over the prairies and the mountain ranges. He 
has since been president of the Geological Society of France.
