Inhabits 



This species appears by the figures to vary from an inch to an 

 inch and a half long, and the breadth is about two-fifths of 

 the length ; the two larger figures are yellowish brown, and 

 ,. the smaller one (which also differs in having a more slender 

 form, and is probably a different species) is white, with two 

 or three narrow brown transverse stripes. 



BAMFFius. 123. Shell ventricose, white, with acute

Shell half an inch, or sometimes an inch long, and half as 

 broad, with six ventricose whirls ; Mr. Montagu says, that 

 younger shells are most commonly rufous brown, and the 

 ribs, which are seldom less than twenty in number, fre- 

 quently white, but as they advance in age they become wholly 

 white. 



GRACILIS. 124. Shell turreted, with longitudinal 

 ribs interrupted by a flat space at the sutures, 

 and transversely striated ; beak rather long, 

 and slightly ascending.

Shell about seven-eighths of an inch long, and two-eighths 

 broad, of a yellowish white colour, with a white band round 

 the middle of the body-whirl ; it has nine or ten whirls, and 

 eleven or twelve longitudinal ribs ; the ribs are not continu- 

 ous, but are separated by a flat space at the upper extremity 

 of each whirl, and the transverse strise are there continued 

 uninterruptedly in a spiral direction up the shell.

 sub-continuous, and nine equidistant strong, 

 ribs ; beak rather long and straightish.
