in the Bristol Channel area; one obtained off the Eddystone 
measured 7 ft. 4 in. in circumference, and 1 ft. in depth. 
Abundantly off the coast of South Devon Lepralia foliacea 
occurs attaining to a very large size.* It is evidently a 
southern species : but it has been found in the Minch, (Hebrides) 
on the western and warmer side of Scotland, and this is its 
most northern locality. 
This form is common off Budleigh Salterton, Exmouth, 
&c.; it has been found also at Ilfracombe, off Cape Clear, and 
the Isle of Man.

as the specimen here described, and which was given by Mr J. W. Davis to 
the Gloucester Museum.
