There is something so anomalous in the structure of these worms, 

 that we cannot admit the accounts of it to influence our generali- 

 zations until we have further observations, and above all a careful ex- 

 amination of animals of different ages. There is no difficulty in pro- 

 curing material to work upon ; will no British observer take up the 

 subject ? — M. E. Robert on the Habits of Ants. — M. Bouchard-Chan- 

 tereaux on the genus Productus, in which he proves that the dorsal 

 valves of these shells is not imperforate as is generally supposed, but 

 the contrary, and attached by a ligament like its allies. — Compara- 

 tive history of the Metamorphosis and Anatomy of Cetonia aurata 

 and Doreus parallelipipedus, by M. Leon Dufour : an elaborate paper

 Toulon Roads. This paper wants figures.

 vegetable pathologist, in which it is shown that the disease depends 

 on the presence of a parasitic fungus. — On two plants new to the

Botany. — On the Distribution of the Arborescent Vegetables on 

 the coast of Scandinavia, and on the north side of the Grimsel in

 beech, the succession of trees is the same on the Grimsel and in the 

 North." — On the genus Xiphophora, and on the question whether we 

 find in the Fucacea the two modes of propagation observed in the 

 Floridecd ? by Dr. Montagne. — On two genera confounded with 

 plants of the family of Myrsinacece, by M. Alph. DeCandolle : these
