“Genus Conorbela n.g.
Type: Bela antarctica Strebel
A new genus is required for this shell, which has little in common with the several other Antarctic and Subantarctic species ascribed to 'Bela' auct. by Strebel (1908).
The shell is comparatively large, thin and ovate-biconic with a prominent, flat, sloping shoulder defined by a rounded peripheral keel. The protoconch, so far as can be judged from available material, is relatively large, dome-shaped and paucispiral. The anterior canal is spout-like, very little produced but slightly constricted by a spiral termination to the smooth, arcuate columella. The posterior sinus is a broad, very shallow arc extending from the suture to the peripheral keel. The operculum is irregularly ovate, with a terminal nucleus, vestigial, occupying only a third the linear dimensions of the aperture. No radula was located.
The form of the sinus suggests relationship with the Conorbiinae and the presence of an operculum disassociates it from Gymnobela, the only other Turrid genus of similar form. Except for the lack of columellar plaits and the shallow but definite posterior sinus, Conorbela resembles the Cancellarid Admete carinata Watson and the Volutid, Paradmete percarinata n.sp.”
