II HABITS OF CARNIVOROUS SNAILS AND SLUGS 55 



Aerobe caffra Fer. in numbers was after an engagement between 

 the Kaffirs and Zulus, when they might be observed streaming 

 from all points of the compass towards the field of slaughter. 

 The Cuban Oleacina are known to secrete a very bitter fluid 

 which they emit ; this perhaps produces a poisoning or benumb- 

 ing effect upon their victims when seized. They devour oper- 

 culates, e.g. Helicina regina and sagraiana.^
