The blemished Nassa. Shell ovately conical, oblique, 

 light brown, last whorl stained with blackish ; spire 



rather short, sharp ; whorls ribbed, ribs tubercled at

The lip of this species is peculiarly thickened at its junc-

Species 167. (Mus. Cuming.) 



Nassa tessellata. Nass. testd ovato-conicd, solidiusculd, 

 lutescente-albd, castaneo tessellatim fasciatd ; spird 

 acuta ; anfractibus rotundatis, lomjitudinaliter plicato-

 plicately ribbed, crossed with noduled ridges ; aper- 

 ture small, interior denticulated, columella excavated, 

 roughly callous, lip varicose. 



Hab. ? 



The transverse bands of this species appear tessellated, 

 through being omitted, so to speak, in the interstices be- 

 tween the ribs.
