volved upon him, we shall without further remark wait patiently but 
anxiously for the appearance of the volume. The greater portion of 
the fishes noticed in this essay have been previously described in 
Histoire Nat. des Poissons, or by Hamilton Buchanan, to whom refe- 
rence is frequently made. 
Mollusques, par G. P. Deshayes. Commences by " Reflexions 
sommairessurrimportancedel'etude des mollusques appliquer a This- 
toire chronologique du globe terrestre." Of the shells twenty -one 
species are described, and they are all figured ; among them seven 
from the land and fresh water, which are interesting on account of 
so few, until lately, from these localities being attended to. Helix, 
Cyclostoma, Planorbis, Limnea, and Paludina. The essay is conclud- 
ed by an interesting table of the living shells of India and the Me- 
diterranean, found in Europe in a fossil state, with the localities 
where the fossils occur. 
Insectes, par F. E. Guerin Commences by an essay, " Essai 
d'unnouvelle arrangement des hemipteres de la section des Homopte- 
res, et revision de la tribu des Fulgorelles." Several new genera 
are proposed; forty-one species are described as new, and all figured; 
and it may be mentioned that the authors of the mollusca and insects 
have added Latin specific characters to the species they describe, 
which we consider an improvement upon the other essays in the 
volume. 
Zoophytes, parR. P. Lesson. Only two species are described, the 
one Tubastrea coccinea, Less, from one of the Society Islands, and 
Sarcophyton lobulatum, Less, from Port Praslin in New Ireland. 
Both are beautifully figured. 
III. Neue Wirbelthiere zu der Fauna von Abyssinien gehorig, ent- 
deckt und beschrieben, von Dr EDWARD RUPPELL. Lieferung 1, 6. 
Frankfurt, 1835-1836. 
THIS work is a continuation of the former " Zoologischen Atlas 
zu der Reise im Nordlichen Afrika," published by the very en- 
terprizing and scientific traveller whose name it bears^and to whose 
energies the town of Frankfort on the Maine is indebted for a zoo- 
logical museum of the first importance, indeed, so rich, that it must 
be rated next to the large national collections of England, France, 
Prussia, and Holland, and before any others of the principalities or 
towns of Europe. 
This collection of Abyssinian Vertebrata is published in numbers. 
It commenced 1st January 1835 ; a number appears every three
