globe, a theme of immense importance, which embraces the 

 greater part of Geology, and which M. Deshayes here 

 alludes to incidentally, but which he has elsewhere deve- 

 loped as the importance of the subject deserves.* 



In the second part, the author describes twenty-one new 

 species of MoUuscs, discovered by M. Belanger. All the spe- 

 cies are figured, and amongst them we remark Helix Beian- 

 gerif Desh. ; H. Semifusca, of Pondichery, id. ; Cylostoma in- 

 dicum, id. of the Isle of Elephanta near Bombay ; Cyclost. 

 Aurantiacunif id. of Pondichery; Planorbis exustus, id. of 

 the coast of Malabar ; Palndina Bengalensis^ Lamark, found 

 on the river Ganges ; Buccimum Blainvillei, Desh. of the 

 coast of Malabar; and the B. conoidale, id. of the Straits of 

 Sunda; the Nerita intermedia^ Desh.; and the Ranella 

 margaritula, id. of the Malabar coast ; the Pyrula fulva, id. ; 

 and the Purpura squamosa^ id. both of the Isles of Sunda, 

 but the latter also on the Eastern coasts of India. 



M. Deshayes concludes this catalogue raisonnee by a 

 tabular view of the fossil shells of Europe, as compared 

 with the living species now inhabiting the Mediterranean 

 and Indian seas. His views, derived from a comparison of 

 the species common to the Indian and Mediterranean seas, 

 afford a solution of the problem of the ancient communi- 

 cation between those seas. 



M. Guerin, who has had the insects as his part of the 

 zoological collections of M. Belanger proposes in the first 

 chapter, a general revision of the genera and species belong- 

 ing to the tribe Fulgorelles^ (or fire flies,) and affords his 

 ideas of the classification of insects chiefly inhabiting India. 

 The second chapter is devoted to the description of a selec- 

 tion from the new species, the fruit of M. Belanger's travels, 

 many among them occupying an important place in the

 this subject in the CakuUa Journal of Natural History, vol. iii. p. 206.
