LIMN^INJE. 



Genus L I M N ^ A , Lamarck. 



For description of the animal, see Halde- 

 man's Monograph. Lamarck's first species in 

 the " Animaux sans Vert." is the CoJumna 

 flammea, a terrestrial mollusk ; we cannot 

 therefore take it as the type of the genus. The 

 second species is stagnalis, but that is the type 

 of Klein's genus Auricula, If we adopt the 

 latter name in preference to Lamarck's, having 

 priority, the name of the terrestrial genus 

 Auricula, Lam., will have to be changed. 

 Under these circumstances it seems most de- 

 sirable to restrict the Lamarckian generic name 

 to certain species only of the genus, and to 

 separate as subgeneric L. stagnalis, etc., apply- 

 ing to them Klein's name Auricula, thus pre- 

 serving both names. 



The following are the subgeneric divisions 

 and the species belonging to each, those 

 characterized in Haldeman being printed in
