1.-5: 



Voliita crenulata of Lamarck is a much larger shell, 

 and has no canal round the spire, in other respects it so 

 nearly resembles this, that it is strange Lamarck should 

 refer to Brander's Murex suspensus, rather than to his 

 Buccinum scabriculum, as synonimous with it. 



An extremely common shell at Barton. We are 

 obliged to change Brander's name, not only because he 

 has used the same for another shell, but because also 

 they both ditFer from that to which Linneus ap[)lied the 

 name, and to which Brander refers. 



VOLUTA suspensa. 

 Vol. 2.— TAB. CX\.—Fig. 5. 



Spec. Char. Ovate, pointed, obscurely cos- 

 tated, transversely striated ; spire with a 

 broad canal around it bounded by an erect, 

 flat, dentated crown ; base produced. 



.Syn. Murex suspensus, JBra7ider, 70. 



JL HE stri« around the base are sharply elevated, the 

 rest more distant and sunk except the one, at the top 

 of the ribs which rises in minute sharp spines. 



We are indebted to the Rev. T. Cooke, for a speci- 

 men of this rare Barton shell, that proves what we for- 

 merly called a monstrosity of Voluta ambig'ua, to be the 

 Murex suspensus of Brander, but his figure is so small, 

 that its characters are obscure. The above description 

 was therefore necessary to complete the account of the 

 Genus Voluta, and must consequently supply the place 

 of that before irivcn with the fii^urc.
