LIMAX. 



TESTA subirregularis, subquadrata, planulata, 

 calcareo-crystalliiia, nucleo postico, inconspi- 

 cuo, dorso epidermide induto ; spira nulla. 



Though in this work we have generally confined our 

 descriptions and figures to the shells of the Mollusca. in 

 one instance we have represented the animal itself. In 

 the present Genus we are compelled to do the same, because 

 the shell is entirely hidden by the integuments of the 

 animal. 



Limax is a Genus of land shells, which are found 

 enclosed under the scutellum over the thorax of some of 

 the common Slugs. It is in general a rather irregular, 

 ilattish, subquadrate, crystalline, shelly piece ; without 

 any spiral elevation, and covered on the back with an 

 epidermis, which usually extends beyond the edge nearly 

 all around; its nucleus is posterior, and very slightly 

 defined. In some species there is scarcely any shelly 

 piece, and only a few calcareous grains in its place. The 

 Limaces are common, they abound in drains, and under 

 stones ; and are frequently found buried in the ground at 

 a considerable depth.
