Shell ovate, fusiform, solid, brown, with a rather pale posterior band finely regularly spirally striated ; 
spire acute, tapering; whorls flat, last rather ventricose. Mouth white, narrow; outer lip thickened, indexed 
with a broad notch behind, and with a slight reflexed sharp external edge in front; pillar plaited. Length 
Inhab. Pacific Ocean. 
This is the Mitre of which I described the animal in the first number of the Spicilegia ; it is allied to 
M. acuminata of Swainson, but differs in being striated, that! species having the inner lip, like this and the 
following, less thickened and reflexed. 
Mitra 
Shell ovate, conical, solid, pale brown, slightly spirally striated ; spire conical, attenuated, acute. Mouth 
contracted, pale, inner lip thickened, expanded in front; outer lip thickened internally, grooved, with a deep 
groove behind. 
Inhab. Pacific. 
Allied to M. Ziervogeliana, but smoother, and spire longer and more acute. 
Mitra chinensis. t . 35. /. 2. 
Shell ovate, fusiform, solid, pale brown, covered with a smooth, olive, periostracum ; whorls rather round 
behind ; upper ones spirally punctately striated, last with a few obscure grooves in front ; throat pale brown. 
Inhab. China. 
When worn covered with white. Sometimes the striae are deeper than at others. 
CYMBIUM. 
The animal like Voluta, but the respiratory canal larger; the appendix on the right side of the canal is 
bent back, and the one on the left forwards. The foot is very large and longitudinally folded; the hood is 
half circular, with the small tentacles near its edges, and with the eyes far behind their base. The mantle is 
not enlarged nor reflexed. Operculum none. 
I have examined C. porcina and C. Olla.
