The following is a copy of the description by Deshayes, — 



"H. PUSTULA. 



" T. orbiculato-depressa, tenue striata, anguste umbilicata, ; umbilico 

 obtuso; rufa vel pallide cornea; anfr. angustis, convexiusculis, sutura, 

 depressa conjunctis, ultimo basi convexiore prope aperturam deflexo, 

 coarctato; apertura, angusta, arcuata, obliqua, alba; marginibus reflexis, 

 basi dente mediocri, linguiformi, conjunctis; labro bidentato, dentibus

" Ilabite le Texas (Say) (Coll. Ferussac)." 



In the description in French, the shell is said to have 4£ 

 whorls, and to be 4 or 5 mill, in diam. As to the umbilicus, I 

 extract the following passage : — 



" Le dernier tour est convex en dessous ; un ombilic etroit est ouvert 

 a son centre, et cet ombilic est en partie cache par l'extremite du bord 

 droit qui s'implante et se dilate sur son pourtour." 



PfeifFer in Mon. I. describes this species as " subdbtecte jperfo- 

 rata" and gives as measurements — "diam. maj. 6, min. 5$,
