312 JEFFERY: the MOLLUSCA of western SUSSEX. 



I have lately found some small specimens in a marl 

 pit near Woodmancote, at a considerable elevation and 

 far from any permanent water. These were found under 

 some of the larger pieces of loose marl, in summer, when 

 there was no trace of water, though the position from 

 being shaded from the sun was always damp, yet without 

 standing water in winter. 



Ancylus fluviatilis. Common in the clear running streams 

 issuing from the chalk hills, also noted in a tributary of 

 the Rother near Midhurst (sand dis.trict). All appear 

 to belong to the variety albida. 



A. lacustris. Found in a pit at Bosham and also in one 

 at Hayling, in both places generally attached to the 

 stems of the Cat-tail Reed (Typha laiifolia) and of the 

 variety albida in both cases. 



TEERESTEIAL. 



Arion ater. Common and generally distributed : brown speci- 

 mens are not infrequent. 



A. hortensis. Too common in our gardens and fields. 



Limax marginatus. In gardens and about buildings, but not 

 plentiful. I have found it feeding on a Great Spotted 

 Slug which T had killed the day before. 



L. flavus. Common in cellars and drains, under stones, &c. 



L. agrestis. Common everywhere. 



L. arborum. Not uncommon in beech plantations, where it 

 ascends these trees, often to a great height, in showery 

 weather, and frequently remains throughout the day in 

 the nooks under the branches (the arm-pits as it were), 

 but in dry weather retiring to the ground under the 

 shelter of decaying leaves. This slug exudes a great
