 Bda cancellata, Stimpsox, Check Lists, 5. 



Shell rather slender, turreted, with about twenty longitudmal 

 ribs, running a little obliquely to the left, crossed by numer- ^.^ ^^ 

 ous transverse, revolving, raised lines, giving the shell a 1 

 cancellated appearance ; whorls seven, convex ; suture well ^ 

 impressed ; spire gracefully tapering ; apex acute ; columella ^ 

 slightly arched at the upper part : aperture rather narrow, ^'^^^^"^ 

 sub-ovate ; canal short, straight, rather wider at the base ; 

 labrum thin, delicately crenated by the transverse striae. Length, 

 thirteen twentieths of an inch ; breadth, one fourth of an inch ; di- 

 vergence, twenty-two degrees. 



Casco Bay ; taken from the stomachs of haddock in the summer 

 of 1840. It must be regarded as very rare. 



This species is very nearly allied to Murex purpureus, Montagu 

 (" Turton Conch. Diet." 95), but is distinct in having a less num- 

 ber of volutions by three or four, by the direction of the ribs, which 

 are " obliquely to the right" in JI. purpureus ; MontagTi's shell is 

 also described as '• rugged," ^- very rough," &c., terms which will 

 not apply to our shell ; it is also said to 1)C " purple," which color 

 is regarded by tlie author as characteristic ; our shell is variously 

 colored, some specimens being tinged with purple, others are white.
