Dr. MeISNEH on CHAMiELAUCIE^. 



At a meeting of the Linneean Society, held on the 20th ult., the Se- 

 cretary read a paper, by Dr. Meisner, of Basle, on the new Chammlamiem 

 contained in the last collection of Drunmiond's Swan Eiver Plants 

 that formed during an excursion of eighteen months to the northward 

 of the settlement. The paper includes descriptions of twenty-two new 

 species, viz. : — Oenetyllhy^\ Ferticordia^ 1 -, C/iajn^elauchim, 2 ; Pile- 

 ant/ius, 1 ; and Calycothrix, 8. In describing the new species of Ver- 

 ticordia^ the author calls attention to some details of structure, which 

 appear to have been hitherto overlooked or misunderstood, and which, 

 in his opinion, render necessary certain changes in the character and 

 subdivision of that genus, for which he proposes four sections, charac- 

 terized by dilFerences in the number and distribution of the calycine 

 segments, viz.: — 1. Euverticordia (including the section Chrysoma of 

 Sella u er) ; ^,Verticordella ; 3. Catocalypta ; ^\i^ ^, Fennuligera,
