Dr. Dekay, in his Catalogue of Animals of New York, has 

 indicated by name, two new species of Limax, the L. linea- 

 tus and L. marmoratus. As no description or figure of these 

 has yet appeared, it is impossible to determine whether they 

 are identical with any of the species described in this paper, 

 or not. 



Genus Limax, Auctorum. 



LlMAX FLAVUS.

 angustis instructo ; clypeo ovali, lineis concentricis et maculis orbiculalis ornato ;
