The following list of slugs may interest Derbyshire collectors. 

 With the exception of L. flavus they have been identified by 

 my friend, Mr. W. Denison Roebuck. 

 Arion ater. Common throughout the county. 

 A. ater. v. luteo-albescens. Clifton. 

 A. ater v. plumbea. Rowsley. 

 A. subfuscus. Clifton and country south of Ashbourne. As 



yet I have not taken this species in any limestone district. 

 A. subfuscus V. brunnea. Clifton. 

 A. subfuscus V. rufo-fusca. Clifton. 

 A. hortensis. Throughout the county. 

 A. minimus. Clifton and Rowsley, 1889. 

 A. circumscriptus. Throughout the county. 

 Limax agresfis. Very common throughout the ccunty. 

 L. agrestis v. nigra. Clifton. 

 L, arborum. Common along the walls and banks on the 



road between Hathersage and Bakewell. 

 L. arborum v. nemorosa. One or two specimens of this 



variety with the above. 

 L. maximus. Common in a cellar at Clifton. 

 [L. flavus. 1 have heard of this, described as 'a large yellow 



slug with a shell, in the cellar.' Clifton]. 



Arion ater van bicolor in Devonshire and the 



Isle of Man. — I have lately had the pleasure of seeing, 

 through the kindness of my friend, Mr. Lionel E. Adams, B.A., 

 a number of fine examples of this beautiful variety, which he 

 and Mr. C. Oldham found about the end of August in South 

 Devon, where they failed to observe the typical form. About 

 the same time I received another fine example, taken at Douglas, 

 Isle of Man, by Mr. F. Taylor.— W. Denison Roebuck, Leeds.
