H. with a fub-pellucld, brown, horn-coloured fliell, 

 with fix fpires, tapering to a fharp point; the volutions 

 are a little rounded, but not much elevated, (lightly 

 wrinkled longitudinally, and fometimes marked with ir- 

 regular traufverfe ridges, particularly on the body whirl: 

 aperture oval, nearly half the length of the (hell; outer 

 lip thin; pillar lip replicated, in old (hells forming a 

 flight cavity behind; infideglolTy purpliQi-brown, fome- 

 times dark-purple. Length commonly about three-quar- 

 ters of an inch ; breadth three-eighths; but fometimes, 

 though .rarely, exceeds an inch in length. 



This fpecies is much more (lender at the bafe than the 

 fiagnalis, and more gradually taper. It is not uncom- 

 mon in watery ditches, in low fwampy fituations, in va- 

 rious parts of the kingdom ; it does not, however, appear 

 to be fo generally known as H.Jlagnalis, and polfibly 

 has fometimes been confounded for the young of that 

 fpecies ; as was the cafe with Mr. Pennant. Do6tor 

 Pulteney's H. fragilis is only a variety of this (hell,

 us with a fpecimen. 



The palujiris is generally covered with a dark epider-
