III. Description of anew species of the genus Argonauta, by M. E. 

 L. Lorois (p. 9). 



This species of Argonauta is dedicated by its describer to the gen- 

 tleman who brought it from the Pacific, M. Noury, the captain of a 

 French frigate. It is characterized as follows : — 



Argonauta Nouryi. Testa parvula, involuta, elongata, tenui, trans- 

 lucida, albido-grisea, rugis lateribus undulatis, spira tantum carinata, 

 tuberculis carinarum nigris, minimis, linea alba separatis, ultimo an- 

 fractu subrotundato, ad spirse carinarum prolongationem paulisper 

 depresso. Long. .58 mill. ; larg. 35 mill. 



It is figured in the plate accompanying the number. 



IV. Catalogue of the Molluscous animals inhabiting the coast of 

 the " Charente-Infcrieure," by M. Henri Aucapitaine (pp. 10-21). 



This catalogue inchides 164 species, belonging to 75 genera; it is 

 accompanied by a few notes relative to some of the species. 



V. Descriptions of four new and remarkable Coleopterous insects, 

 by M. Reiche (pp. 21-25). 



This paper consists of descriptions of four Lamellicorn beetles, three 

 of them of rather large size. They are nicely figured in outline in the 

 plate accompanying the part. The first, 



1. Democrafea Bnrmeistei'i, differs from the type of the genus, 

 D. Croesus, Newm., in its smaller size, the blackish tint of its head 

 and thorax, and in the punctuation of the elytra. It is from Quito. 



2. Megalosoma Mars. This insect is very nearly allied to M. Ac- 

 tceon. It is from tropical America, about the Rio Negro. 



3. Anoplocnemus Dejeanii; probably an inhabitant of the East 

 Indies. 



4. Anoplocnemus La/ertei, a fine species from Australia, which 

 M. Reiche thinks may probably form the type of a new generic group 

 characterized by its exposed eyes, the straightness of its mandibles, 

 and the form of its thorax. 



The remainder of the number is occupied by reports of the sittings 

 of the ' Academic des Sciences ' of the 5th and 12th of January 1852, 

 and notices of two or three new works.
