Hab. B;>t Island, Torres Straits, 1 1 fathoms. 



Reeve in Concologia Iconica, pi. 26, species 118, figures Murex 

 breviculus of Sowerlry, and puts Murex tetragonus, Broderip down 

 as a synonym. The specimen dredged answers to Broderip's 

 description of Murex tetragonus ; and does not answer either to 

 Reeves' description or figure ; the shell figured by Reeve is a true 

 figure of Murex breviculus, Sowerby, a much larger and finer shell.

Shell somewhat pyriformly ovate, rather rough, spire short, 

 sharp-pointed, whorls 5-^, five varicose, on the whorl ending in the 

 form of a canal ; varices laminated, interstices between the varices 

 crossed with four laminated ribs ; on the last whorl below some- 

 what smooth, forming hollow pits, suture minutely laminated, the 

 varices on the upper whorls small, more like rounded nodules, 

 laminated and excavated behind, white stained with brown 

 between the varices, aperture roundly ovate, interior of aperture 

 glossy white, edge of peristome denticulated, canal rather short, 

 attenuated, and recurvated. 



Length 13 J, breadth 7h, height 6| lines.
