A. single specimen only has been received of this pretty shell. The 

 combination of colour and markings renders it an object of much 

 beauty. The cancellation produced by the chocolate bands crossed 

 by the waved longitudinal stripes on the white ground give it 

 a latticed appearance, which is sharply defined within the interior ; 

 under the lens the nepionic whorls show the usual thimble like 

 sculpture of Brymmis.
