32 CATALOGUE OF THE MOLLUSOA 



excellent little work, " Historia Molluscorum Sueciaa."* Wishing 

 to have the opinion of the Rev. B. J. Clarke, whether this was 

 the young of any of the species he has so admirably described, 

 we sent him a drawing and description of it. Mr. Clarke states 

 that but for the black tentacles he would have thought the 

 drawing to represent the young of Limax flavus, but taking the 

 description into consideration, he thinks us justified in consider- 

 ing it distinct. The blue tentacles are a permanent character in 

 L. flavus, and M. Bouchard Chantereaux says that its mucus is 

 colourless. 



6. L. AGRESTis, Linn. 



Limax agrestis, Gray Turt. Man. 117 ; Clarke in Ann. 

 Nat. Hist. xii. 338, t. 12, f 13. 

 In fields and gardens ; much too common. 



7. L. BRUNNEUS, Brap. 



Limax brunneus, Johns, in Berw. C. Proc. i. 154 ; Gray 

 Turt. Man. 117. 



In damp woods, frequent. 



This species was introduced into our Fauna by Dr. Johnston, 

 and considered to be the L. brunneus of Draparnaud, partly, per- 

 haps, in conformity with our opinion. Draparnaud's species, 

 however, is very obscure, and was unknown to Ferussac. M. 

 Bouchard Chantereaux finds a species in the north of France, 

 which he considers to be the L. brunneus. His description of 

 it agrees pretty well with our animal, but a comparison of the 

 specimens would be necessary to pronounce on their complete 

 identity. It is quite distinct from the dark variety of L. 

 agrestis. 



*As this is the first time the species has been noticed as British, we insert 

 Nilsson's description : — " Animal parvum, vix 1\ une. longum. Clypeus lineis 

 subtilibus concentricis striatus, apertura laterali postica. Collum supra linea 

 longitudinali elevata, lateribus subreticulatis. Dorsum postiee compressum. 

 Color clypei et dorsi postici luteus; dorse supra luteo-virescente levissime 

 cinerascente, subtus albo. Tentacular caput, et linea colli utrinque nigra. 

 Mucus luteus. Habitat in syWis inter folia putrescentia, humida, rarius." — 

 Nils. Hist. Moll. Suec. 10.
