158 Miscellaneous. 



classed in sets, and offered for sale at the rate of 1/. 155. the 100 

 species of Scottish mosses, and 21. the 100 for those of America; of 

 which latter, however, the northern and southern will form se- 

 parate sets, several of the northern having been published pre- 

 viously to Mr* Drummond's death, which are already in the possession 

 of those who might therefore now wish to purchase only the southern 

 species. The exact number of each set cannot clearly be ascer- 

 tained at present (they being in the charge of a botanist, competent 

 to the task, who is naming them), except as regards the Scottish 

 mosses, of which some sets are already prepared, amounting to from 

 220 to 230 species. It is reckoned, upon the average, that there 

 may be about 80 or 100 of the southern American mosses, and from 

 150 to 180 of the northern ones. They are good specimens and in 

 beautiful preservation, and can be had loose or arranged in volumes, 

 at the option of the purchaser. Application for sets may be made 

 to Sir W. J. Hooker, in whose hands there still remain a few sets of 

 Mr. Drummond's phsenogamous plants from Louisiana and Florida. 



DESCRIPTION OF THE ANIMAL OF PANOPJEA AVSTRALIS. 



M. Valenciennes has recently presented a memoir on this subject 

 to the Academy of France detailing the internal and external organi- 

 zation of Panoptea australis. The most recent works on Mollusca 

 enumerate but three species. M. Valenciennes has however shown, 

 that by combining the materials scattered in the various collections 

 and works, that we are at present acquainted with fifteen species of 

 shells belonging to this genus, five of them living in the different 

 seas of the globe, and the other ten fossil, belonging to the various 

 layers of calcaire grossier or to the chalk. Of the living species 

 two are found fossil, but completely identical, in the recent forma- 

 tions of the argillaceous marls of the environs of Palermo ; one spe- 

 cies belongs to the Mediterranean, the other to the Norwegian seas.

INDUSTRY AND METAMORPHOSES OF THE ODYNERI. 



M. Leon Dufour has recently presented to the Academy of France a 

 memoir on the industry and the metamorphoses of this genus of insects, 

 describing at the same time several new species. Since the time of 

 Reaumur, who made such interesting researches on this subject, sci- 

 ence has remained quite at a stand-still. M. Dufour confirms the 

 correctness of the facts advanced by Reaumur, corroborating them 

 by the description of an analogous but distinct industry in some new 

 Odyneri.— Compte Rendu, No. 10, Sept. 1838.
