with white longitudinal streaks : spire consisting of 

 from nine to twelve somewhat rounded volutions, 

 ending rather acutely : aperture oval, longer than

 perforation at the pillar. 



Common on sandy maritime pastures. 



68. BULIMUS artlculatus. Shell conic, ventricose at 

 the base, white, with longitudinal stripes of chain- 

 like brown spots. 



Bulimus articulatus. Lamarck, vi. ii. 124. 



Shell five eighths of an inch long, and three eighths 

 broad, quite conic, and so abrupt at the base of 

 the lower volution, as to have the appearance of 

 being somewhat carinated : colour whitish, glossy, 

 with numerous longitudinal rows of pale brown 

 chain-like spots, resembling figures-of-eight linked 

 together : the tip black-brown : on the back of 

 the lower volution are two brown narrow bands, 

 one of which penetrates the aperture, and the 

 other is continued round the junction of the su- 

 tures : spire consisting of ten very little raised 

 volutions : aperture roundish-oval, as wide as it is 

 long, with the margin reflecting over the pillar and 

 forming an umbilicus. 



A few of this very beautiful and distinct species were 

 sent us from the plains about Penzance in Cornwall.
