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 al'his- 

 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- 

 deckl 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
