CYMBIUM. 
Puate VIII. 
Species 4. (Fig. 6, c, Mus. Cuming; Fig. d, e, are larger and darker than in any specimen that I have 
Mus. Brit.) seen, and the scales which have not reached to the length 
to which they would be developed in another whorl are 
stained with the same dark chestnut as the bands. In 
the younger specimens, Fig. 4 d, 4 e, from the collection 
of the British Museum, the chestnut blotches are only 
faintly indicated, and the network is stronger. 
The specimens of Cymbium ducale figured in this Plate 
represent the species in young and in middle stages of 
growth, with the dark bands more or less conspicuously 
developed, but the network constant. In the shell Fig. 
46, 4c, in Mr. Cuming’ collection, the chestnut blotches 
December, 1860.
