134 IIMACIDJE. 



This kind of slug is nocturnal, but very active. Its 

 slime is abundant and stains linen of a yellow colour. 

 It appears to be fond of bread, cooked vegetables, and all 

 sorts of kitchen refuse. 



It is probable that the L. flavus of Miiller may be a 

 variety of Avion ater, because he describes the shield as 

 not having any concentric wrinkles, although in the 

 same description he also notices a yellow slug which 

 seems to belong to the present species. This is the 

 L. variegatus of Draparnaud ; and its shell is probably 

 the Limacella concava of Brard.

L. agrestis, Linn. Syst. Nat. ed. x. i. p. 652 ; F. & H. iv. p. 13, pi. D. D. D. 

 f. 3. 



Body spindle-shaped, slender, ash-grey with a reddish or 

 yellowish tinge and sometimes mottled, nearlj^ smooth : shield 

 rather large, more tumid behind, the concentric striae more 

 remote and indistinct than in any of the other species : tentacles 

 dark grey : hack obhquely, but not strongly, keeled towards 

 the tail: foot having very pale sides: slhne milky. L. 1*5. 

 B. 0-4. 



Shell obliquely oval or inclined to oblong, concave on the 

 under side, rather thin, with indistinct hues of growth, and 

 marked obliquely by exceedingly minute striae which cross 

 each other: boss very small, slightly projecting behind on one 

 side : margin membranous, rather broad, and obliquely striate. 

 L. 0-2. B. 0-1. 



Habitat : Fields, gardens, and woods throughout the 

 British Isles. The shell is also one of our upper tertiary 

 fossils. Its foreign distribution extends from Siberia to 

 Corsica and Algeria, and (according to Lowe) Madeira. 



This slug is a great pest in the kitchen garden, and 

 does not even spare succulent leaves and roots of flower- 

 plants. Mr. Whiteaves says that it also feeds on earth- 



* Inhabiting fields.
