The var. y, is the only one I have seen British: 
var. 6, is not I think described by any Author; I have 
one specimen only of it, and am ignorant of its exact 
locality : var. «, and specimens approaching the others, 
are not rare at Grignon. Some of the English speci- 
mens are very like var. 6, while others have hardly any 
appearance of coste, except upon the spire ; these latter 
are most properly what Brander has called Murex tur- 
gidus. I am indebted to Miss Teed and another Friend 
for the series by which I have been enabled to trace the 
connection with the French varieties; they are from 
Hordwell Chiff.
