Helix Foremaniana Adams Contr. to Conch. Nr. 5. p. 80. 
(„Helix Foremaniana. Shell ovoid, with a scarcely perceptible 
obtuse angle on the periphery: white, with a very pale horn- 
coloured epidermis; with fine irregular strie of growth, and 
sometimes on the lower side of the last whorl with inequi- 
distant unequal concentrie strie: spire very much elevated, 
with very convex outlines: whorls seven and one half, quite 
convex, with a well impressed suture ; last whorl very 
convex beneath to Ihe centre, wilhont any indenlation in 
the umbilical region: aperture obliquely lunate, wider below 
than above; wihin, a little beiow the middle of the right 
side, is a long lamellar tooth, commeneing abruptly in the 
bottom of the aperture , and gradually diminishing in height 
to its terminalion a little within the margin; with a wide 
irregular toolh on Ihe end of the columella: labrum sharp: 
umbilieus wanting ete. 
Greatest breadih .78 inch. ; least breadth .@3inch.; height 
.9 inch.®) 
Obs. Vergleichen wir die Pfeifferische Diagnose mit 
der Adams’schen Beschreibung, so sehen wir hier wieder, 
dass er eine ganz andere Schnecke beschrieben hat, 
Pfeiffer sagt: anfr. convexiusculi, Adams: e toto convexi; 
Pfeiffer: anfr. ultimus basi profunde impressus, Adams: 
anfr. ultimus subtus convexissimus usque ad centrum, 
sine ulla indentatione in regione umbilicali; Pfeiffer : in- 
tus lamella valida subspirali, pluries interrupta munita, 
Adams: intus dens lamellaris longa, ex fundo aper- 
tur subito oriens, altitudine versus ejusdem termi- 
nalionem pone marginem gradatim decrescens;- Pfeifler: 
margine columellari calloso-incrassato, Adams: dens lata 
irregularis ad basin columell. 
Die Bildung der basal zahnartigen Lamelle beweist, 
dass Pfeiffer die gleiche Art beschrieben hat, .die früher 
Dillwya und Adams unter H. epistylium verstanden, und 
Beck ais die Chemnitzische Trochus australis erkannte.
