328 Rev. Canon Norman's Revision 



Suborder I. GEOPHILA. 



A. MONOTREMATA. 



Fain. 1. Testacellidse. 



Genus Testacella, Cuvier. 



176. Testacella haliotidea^ Drap. 



Var. scutulum, Sowerby. 



177. Testacella Maugei, Fdrussac. 



This species is completely naturalized and widely spread 

 now in gardens throughout England, and has been also found 

 in Jersey by Mr. Bull. 



Fam. 2. Limacidae. 



Genus 1. LiMAX, Linn^. 



178. Limax maximus, Linne. 



179. Limax marginatus, Miiller, =L. arhorum, Bouch. -Chant. 



This is generally considered, and I think with reason, to be 

 the L. marginatus of Miiller ; but Jeffreys in Brit. Conch, 

 vol. i. followed Draparnaud in applying that name to L. cari- 

 natus ; but see vol. v. p. 155. 



180. Limax jiavusj Linn. 



181. Limax agrestisj Linn. 



182. Limax IcBvis, Miiller, = L. hrunneus, Bouch.-Chant. 



Jeffreys, who had little studied other Alollusca than those 

 which bear external shells, supposed that this was a variety 

 of L. agrestis. It is very different in form from that species, 

 very local, and inhabits, so far as I have observed, marshy 

 meadows. Jeffreys at a later period described it (see Brit. 

 Conch, vol. V. p. 156). 



183. Limax tenellus, Miiller. 



The admission of this species into our lists I believe chiefly 

 rests on Mr. Alder's authority. The specimen figured by 

 Forbes and Hanley was found at AUansford, near Shotley 

 Bridge, Co. Durham. All Mr. Alder's original drawings are 

 in my possession, and among them is that of this slug.
