DISPERSAL OF SLUGS. 1/7 



estimate of Mr. Darwin's, even for a distance of 500 

 miles, and remaining alive in the crops of dead birds, 

 they might be drifted on the surface of the ocean 

 possibly to a still greater distance. The late Mr. 

 J. W. G. Spicer, of Spye Park, Wilts, once recorded 

 the shooting of pheasants in the Holt Forest with their 

 crops completely full of a small white slug, but he gave 

 no indication as to whether any were alive,^ and perhaps 

 it is hardly likely that these shell-less creatures can 

 retain life for any considerable time in the warm crop 

 of a bird, and it is to be remarked, also, that they are 

 certainly more likely than snails to be killed or severely 

 injured when picked up and swallowed.
