104 HELICIDiE. 



a fourth of the entire length, and filling- rather more than 

 half the basal width, devoid of any teeth or laminae. Lips 

 disunited, the outer one more or less arched, not strength- 

 ened by any external rib or callosity, neither dilated, nor 

 folded back ; pillar lip not much curved, oblique at the 

 edge, broadly reflected above. Length rather more than 

 the tenth of an inch. 



The animal is dark grey above, paler beneath ; its lower 

 tentacles are almost obsolete. 



It is widely diffused, but local, though occurring in the 

 three kingdoms and in the Isle of Man (T. Hincks). It 

 is found chiefly among grass and dead leaves in woods. 

 Mr. C. C. Babington has observed it in great abundance 

 in Lanarkshire on the under surface of the frond of 

 Aspidia in autumn (Lowe). 



P. minutissima, Hartmann. 



Minute, cylindrical ; with distinct close-set raised wrinkles ; 

 mouth edentulous ; outer lip scarcely at all reflected.
