having subsutural and peripheral bands of yellow. No streak behind the lip, 
no columellar patch. The apex is white. 
3. Var. zntensior (fig. 100). — Shell solid, lip wide; ground-colour olive-brown or 
purplish brown; light bands at periphery and suture; darker bands in the usual

MÖLLENDORFF hat im Verzeichniss diese Varietäten angenommen, sie aber in seiner 
Sammlung nicht unterschieden. 
Von €. annulata unterscheidet sich unsere Art sofort durch die ganz eigenthüm- 
liche unten fast rinnenförmig zusammengedrückte, fast dreieckige Mündung mit dem 
auffallend breit umgeschlagenen Mundsaum und den eigenthümlichen Eindruck oder 
Vorsprung am Aussenrand. AÄLBERS führte sie deshalb unter Ortkostylus bei Bulimus auf.
