Major A. R. Hunt took many examples of this fine species 
in Torbay in 1875 and 1877 (see Trans. Devon Assoc. 
Advanc. Sci. Liter, and Art, 1877 and 1888) ; the larger 
specimens weighed from 19 to 40 ounces. Major Hunt 
remarks that these large specimens did not discharge any 
purple, but some pink dye. One of the shells of these large 
specimens which he kindly sent me measures 2\ inches long 
and If inch wide, and exactly corresponds in its characters 
with Mediterranean examples of the same species and size in 
my collection.
