LIMAX CINEREO-NIGER van STROBELI Lessona, 

 NEW TO BRITAIN. 



By W. DENISON ROEBUCK, L.F.S. 



(Read before the Societj', Decemlier iilh, 1012). 



On the 30th September, Mr. Charles Oldham sent me various slugs, 

 amongst which was an example taken the same day in a wood near 

 Marlin Chapel, Berkhamsted, Herts., which is the first I have seen 

 of this variety. It is entirely ashy-grey and corresponds to the 

 description on p. 59 of Mr. Taylor's Monograph, the ground colour 

 showing as paler maculations on the darker surface-coloration. There 

 is also a variety strobeli of Pini, but this is a subvariety of var. 

 cinerea, and has the shield bluish-black instead of the ash-grey of 

 Lessona's variety of the same name.
