information on their organization and critical synonymy. He 

 indicated profusely localities of species which are not com- 

 mon in all places. 



The number of species described is 1631, divided into 575 

 genera. They belong to Phanerogamous plants, to which 

 the author has added some families of Monocotyledones, 

 Cryptogames, Ferns, Lycopadiaceae, and Equisetaceag ; as to 

 the Cryptogamae properly so called, and Agamse, the author 

 has given the simple catalogue of Mosses, Hepaticae, and 

 Lichens. 



Observations on Spermatophora of molluscous Cephalopods,

 tracted from a letter ofM. Milne Edwards, dated Nice, 

 April 28th 1840, and communicated to the Academy of 

 Science by M. Audouin.*

 letter was not sufficiently acquainted with the structure 

 or function of these bodies, and this lead him to make a more 

 minute inquiry than had hitherto been made. He mentions 

 Dr. Peters, a young naturalist from Berlin on a mission to 

 Nice, who joined him in the same investigation, and it is 

 I presume to their joint efforts that we owe the discoveries 

 mentioned in the letter to the Academy. 



The Cephalopods which they procured for examination 

 were the males of the Poulpe commun, Poulpe a-longs bras,
