Q„Helix alUgans. Shei! giobose, conoid : white, witli a yellowish 

 brovvn epidermis: with regulär Striae of growth, vvhich are 

 veiy coarse on tlie spiae, and fine on the last vvliorl : apex 

 very obtuse : spire wel! elevated, with the outüne.s very con- 

 vex above, nearly rectilincar bclow: whorls eight, narrow, 

 rather convex, with a well impi-essed sutare ; last whorl scar- 

 cely convex beneath, with the urabilical region planulate: aper- 

 ture oblique, rather broad, lunate ; with a very prominent sharp 

 slout revolving lamella far vvithln in the lower part of Ihe last 

 whorl: labrum rather thin, sharp: columella moderately dilated 

 , and well rounded : umbilicus wanting. This species reserables 

 II. epislyUum and [J. episiylioides. It is inost casily recogni-

 etc. {ui supra). '-''') 



Obs. Nach Adams' Angabe des Unterschiedes dieser 

 Art von H. epislylium sehen wir, dass er unter dieser 

 letzteren eine mit ausgehöhlter oder vertiefter Umbilical- 

 region versehene Schnecke begreift. 



AI lg. Bern. In dieser Pfeiffer nur nach des Ver- 

 fassers Beschreibung bekannten Art, können wir Nichts 

 anders sehen, als die von Pfeiffer beschriebene Helix 

 epistyiium.
