Dr. Gray, whose politeness in giving shells the Chris- 
tian names of ladies is unrivalled, well distinguished this 
species in 1833; but in his monograph of Volutide, in 
the Museum Catalogue, published more than twenty years 
later, he remarks of this and the preceding species that 
they appear to be varieties of C. diadema. ‘‘ If we select 
certain specimens of each,” says Dr. Gray, “they appear 
very distinct; but if a large number of specimens of dif- 
ferent ages, from various localities, are arranged together, 
the differences gradually merge into each other, and it is 
difficult, if not impossible, to separate them from one an- 
other.” Of the Lamarckian /. diadema and armata this 
may be said truly enough, for they are one species, but of 
C. ducale and Georgine I find no difficulty in separating at 
a glance the largest number of specimens that were pro- 
bably ever brought together. The general form of C. 
Georgine, as represented in the accompanying Plate, is 
constant, with very little modification; the detail of 
painting, described in our next Plate, is even more charac- 
teristic.
