Dr. Binney made a report upon two works of Sig. Aliche- 

 lotti of Turin, recently presented by the author. 



The first, a monograph of the genus Murex, is minute and care- 

 ful in its descriptions, qualities of the highest importance in a work 

 of this kind. The other volume is upon Rhizopoda, or microscop- 

 ic camerated shells. These shells, when first made the subject of 

 investigation by D'Orbigny, were considered as belonging to Ce- 

 phalopoda of as high an order of organization as the larger ani- 

 mals of that family. But later investigations by Dujardin repre- 

 sent them as internal shells belonging to infusorial animalcules, 

 and of the lowest grade of organization. This author's views coin- 

 cide with the latter opinion. 



Dr. Gould remarked, that, in some recent microscopical 

 investigations with Dr. Wyman, on some of the Gastero- 

 podous mollusca, the conclusion had been forced upon them 

 that many of the Infusorial animalcules would be found to 

 occupy a place in the chain of being very little anticipated. 



He hoped soon to present a full development of these observa- 

 tions. He made the general remark that he thought it not safe to
