Bourguignat^ J. R. Mollusques iiouveaux, litigieux ou peu 
connus. Cinquieme fascicule. Paris, 1865, 8vo, pp. 
133-170, pis. 20-28. 
Contains nine Umo and one Anodonta from Spain and Pales- 
tine, and an enumeration of all the species of Najadea known 
from Spain and Algeria. 
Tryon, G. W. American Journal of Conchology. Vol. i. 
(parts 1-4). Philadelphia, 1865, 8vp, pp. 1-387, with 27 
plates and the portraits of four American conchologists, 
Thomas Say, Isaac Lea, C. B. Adams, and Augustus Gould. 
This journal was started in 1865. The contents of the first 
volume are chiefly papers on North- American land- and fresh- 
water shells ; also palaeontological articles are received in it. 
2. Works of a Popular character. 
Frkdol, a. Le monde de la mer. Paris, 1865, 8vo, pp. 632, 
with 21 plates. 
A popular treatise on marine animals generally, containing 
much information on various questions of the day in science and 
scientific industry— for instance, the breeding of oysters and 
mussels {^Mytilus). The coloured plates, representing living 
animals, are highly creditable; some of the Mollusca Nudi- 
branchiata are stated to have been figured here from unpublished 
drawings of M. Deshayes and Quatrefages. 
A similar work in German, much like an abridged translation 
of the French one, has been published by Prof. Schleiden with 
the title ^ Das Leben des Meers.^ 
3. Classification and Morphology of Mollusca in general. 
Morch, O. a. L. On the limits of the subkingdom Mollusca. 
Ann. & Mag. Nat. Hist. xvi. pp. 411-414. 
The author is incliqed to introduce into this subkingdom the 
Platyelmia [Plathelminthes~\ , including Trematoda, Cestoda, and 
Turbellaria, as the nervous system and the generative organs do 
not essentially differ from those of the Androgynous Mollusca ; 
on the other hand, he excludes from the Mollusca the Tunicataj 
Bryozoa, and Brachiopjoda.
