DISPERSAL BY MAN. 229 



creature is a native.^ Jeffreys (1862) remarked that it 

 was still to be found in considerable numbers in the 

 original habitat, and that it had been observed also in 

 other parts of Somersetshire, as well as at Plymouth, 

 Cork, and in his own garden at Norton, near Swansea, 

 which was occasionally supplied with plants from 

 Miller and Sweet^s nursery. The occurrence of the 

 animal in fields near Devizes is noted in Woodward's 

 " Manual," but I find a statement, in 1867, that it is found 

 in that neighbourhood only \N\).QVi g-ardeners are preparing 

 their ground or digging up their crops. The Concho- 

 logical Society's referees have seen specimens from 

 West Cornwall, North Somerset, Dorsetshire, Berkshire, 

 West Gloucestershire, Glamorganshire, Pembrokeshire, 

 Waterford County, and the Channel Isles, and without 

 doubt the creature has obtained a permanent footing." 



BULIMUS GOODALLII Miller. — This snail, which has 

 now a wide range, is said to be a native of the West Indies, 



' Since writing I find, however, that Dr. Scharff, in a recent 

 paper on the distribution of the British land and fresh-water mol- 

 lusca, seems to have regarded this animal as indigenous to our 

 soil, and it is of course c^\X% possible that such is the case. See 

 " Conchologist," ii. (1892), pp. 1-6.
