SYNONYM. 



F, CINEREUS. Nob. Joum, Acad Nat. Sc. vol. 2, p. 236. 



DESCRIPTION. 



Shell rather short fusiform ; cinereous or pale reddish 

 brown, with two obsolete rufous bands ; somewhat pon- 

 derous, with large approximate, longitudinal, thick ribs or 

 undulations, about eleven in the body whorl ; and trans- 

 verse, elevated lines forming shallow grooves between 

 them, and somewhat alternately smaller: spire tapering, 

 acute : lahrum a little crenate exteriorly by the elevated 

 lines ; within striate and purplish : beak short, a little re- 

 flected. 



OBSERVATIONS. 



This species is common in the estuaries of the eastern 

 shores of Maryland and Newjersey. It has considerable 

 resemblance to two figures in Lister's Hist. Conch, pi. 

 924, f. 16, b. and pi. 939, f. 34, a. The first of which is 

 considered an uncertain figure and the latter is said by 

 Dillwyn to be the undalus and is interrogatively referred 

 to by Lamaick. Our shell certainly approaches the genus 

 Purpura in habit, but it cannot enter with Lamarck's cha- 

 racters. 



REFERENCE TO THE PLATE. 



The two middle figures.
