352 TURRITID^, 



stomachs of fish. It is one of the shells common to both Atlantic 

 shores. Halifax (Willis); Eastport (Cuuper). 



This is a very pretty shell, and is not likely to be confounded with 

 any other except B. harpularia. From this it is distinguished by 

 being a more delicate shell, by its color, by the smaller numl)er of 

 ribs, and by the remarkably turreted appearance of the whorls. 

 The raised line, revolving at their angle, is so great as to produce 

 a small tubercle there, on each of the ribs. The aperture is usually 

 about half the length of the shell ; but there is a variety in which 

 the aperture is about one third the length of the shell, and the ribs 

 are more numerous. Mr. Sowerby intimates that our shell may 

 not be identical with the European type ; but, on the whole, I can- 

 not persuade myself to regard them as different. The variety is 

 like the Murex angulatus, figured by Donovan. 



Bela harpularia.

Shell long-ovate, pointed, turreted, llesh-eolored ; whorls angular above, with 

 about sixteen oblique, rounded folds and numerous revolving lines.

Shell ovate-oblong, turreted, of a l)rownish flesh-color, composed 

 of six or eight angulated whorls, flattened above the angle, so as to 

 form a slightly sloping shoulder ; lower whorl more than 

 half the length of the shell, having aljout eighteen oblique, 

 rounded plaits or ribs, vanishing before they reach the beak, 

 and crossed by fine revolving lines, most conspicuous in the 

 interstices ; the upper whorls are marked in the same man- 

 ner ; beak white, short, somewhat curved, and ])ointed ; aj)- 

 B harpu- epture narrow, broadest and ano-ular behind ; the outer lip 

 sharp; inner lip white, smooth, and moderately arched, 

 twisting outwards at the commencement of the beak. Length, half 

 an inch ; breadth, one fourth of an inch ; divergence, forty-eight 

 degrees. 



First found by Mr. Couthouy, in fish taken near Nahant, and fre- 

 quently olitained since from the same locality. Banks ( Willis) ; 

 Eastport (Cooper) ; fossil, Montreal (Daivsori). 



It bears a close resemblance to B. turricula; and Mr. Sowerby
