210 MOLLUSCA. 
Length an inch and an eighth; breadth three-fourths of an inch ; 
height seven-eighths of an inch. 
Purchased at Singapore, by Mr. Rich, and is known to be native at 
the Molucca Islands. 
Distinguished by its globular form, shining surface, peculiar coffee- 
coloured ground, with delicately painted, feathery ridges, and the 
large, white, elevated, columellar callus. It accords with the figure 
in Chemnitz of Turbo papyracea, but that shell is described as_per- 
fectly smooth. This shell certainly does not belong to the genus Turbo. 
Figures 249, 249 a, 249 4, three views of the shell.
