CYMBIUM. 
Prate XVIII. 
Species 9. (Fig. 6, Mus. Cuming.) 
The shell here figured is a specimen of Cymbiwm Indi- 
cum, of ordinary size, fully coloured. Unlike other Cym- 
bia, the dark painting appears in three bands, an additional 
band being present in place, as it were, of the corona of 
scales. The bands are more frequently broken up into 
clouded irregular blotches. 
Species 10. (Fig. a, Mus. Cuming ; 
Fig. 6, c, Mus. Brit.) 
CYMBIUM TESSELLATUM. Cymb. testd ovatd, vel pyri- 
formi-ovatd, ventricosd, lutescente, castaneo sparsim 
maculata, interdum obscure bifasciatd, spird brevi, plus 
minus tmmersd, anfractibus superné subcanaliculatis, 
squamis appresse decumbentibus coronatis, columella 
quadriplicata. 
THE TESSELLATED CympBrum. Shell ovate, or pyriformly 
ovate, ventricose, yellowish, sparingly blotched with 
chestnut, obscurely two-banded, spire short, more 
_ or less immersed, whorls slightly channelled round 
the upper part, coronated with appressly decumbent 
scales, columella four-plaited. 
Voluta tessellata, Lamarck, Anim. sans vert. vol. x. p. 377. 
Melo tessellatus, Broderip. 
Hab. Eastern Seas. 
In colour and marking this species resembles a pale 
CO. Indicum, but it is at once distinguished by the very 
characteristic corona of decumbent scales. In the young 
state, Fig. 10 4, c, the scales are comparatively erect ; in 
the mature shell, Fig. 10 a, they become quite decumbent 
over the apex of the spire. 
February, 1861.
