THE CONCHOLOGIST. 



Var. albidus, Picard. 



4. Deddington. — Single specimen. 



Agriolimax laevis, Miill. 

 This active and interesting slug is a some- 

 what uncommon form, and is never met with 

 in any large numbers. It frequents damp and 

 w'et places, and requires carefully looking for. 



1. Banbury. — In dead leaves by Rroughton 



Castle. 



2. Chipping Norton. — Few under logs of 



wood. 



3. Wychwood and Charlbury. — Met with 



sparingly, near Charlbury. 



6. Oxford. — Fairly common. 



7. Swincomb.^Occasionally met with. 



Amalia gagates, Drap. 

 This is not at all a common form, being 

 somewhat local, and confined to the Northern 

 divisions of the county. 



1. Banbury. — Met with sparingly, near Little 



Bourton. 



2. Chipping Norton. — Two specimens near 



Lidstone. 



Var. rava, Williams. 



I have met with a variety which agrees with 

 the description of this form, viz. : " animal 

 drab coloured, slightly fuscous, with the mantle 

 of a lighter colour than the back." 



I. Banbury. — Near Little Bourton. 



Amalia sowerbyi, Fer. 

 -- A. cariua/a, Leach. 



Not an uncommon form, but never met with 

 in large numbers. 



1. Banbury. — Broughton. 



2. Chipping Norton. — In two gardens at 



Kingham (S. Spencer Pearce). 



5. Bicester. — Weston-on-the-Green, Rev. A. 



Matthews (Norman, 1857). 

 7. Swincomb. — Few, near Swincomb. 



ARION, Fer. 



Arion ater, L. 



This fine slug is found in great abundance 

 throughout the county. Some specimens I 

 collected near Bodicot were covered to an 

 unusual extent with the small white parasites, 

 F/iiIodro/)ius limacum, Jenyns. Simroth has 

 pointed out that slugs of a red colour are re- 

 jected by birds, &c., or only the viscera eaten, 

 I have noticed that the variety nifus Linne. of 

 this species is seldom if ever eaten by birds. 

 A very erroneous idea is prevalent amongst 

 Naturalists in general that slugs and snails are 

 exclusively herbivorous ; judging from my ex- 

 periments on this and other species I am of 

 opinion that they will eat almost anything, as 

 has, since my observations, been shown to be 

 the case.* 



Var. rufus, Linne. 



I. Banbury. — Often met with, Banbury, Blox- 

 ham, and Broughton. 



6. Oxford. Woodeaton, &c. — The Rev. S. 



Spencer Pearce, B.A., records "a hand- 

 some dark brown variety in the Kim- 

 meridge Clay-pits, at Shotover hills," 

 which I think may be referred to this 

 variety. 



7. Swincomb. — Not uncommon. 



Arion subfuscus, Drap. 

 A plentiful and well-distributed species, 

 varying much in colour, the specimens in the 

 southern parts of the county being generally 

 much lighter. 



Arion hortensis, Fer. 

 A common form throughout the county. 

 A very lazy and inactive species. 



Var. rufescens, Moq. 

 I. Banbury. — Met with on several occasions. 

 4. Bicester. — Two specimens.
