Genus Baryspira Fischer, 1883.
Type: Ancillaria australis Sowerhy.
Baryspira electa n. sp. (Fig. 73.)
Shell somewhat small, subcylindrical; spire about equal in height to aperture. Callus of spire with weak spirals. Callus of inner lip extending upwards to apex of spire, its outer margin in a shallow sigmoid curve. The lower part of the columella bears six about equal spiral folds, the top one somewhat stronger. The interspace below it bears a weak thread.
Holotype in Dominion Museum.
Height, 22 mm.; diameter, 8 mm.
Closely related to B. hebera (Hutton) but differing in the disposition of the apertural and spiral callus; the sinuous outer margin

on the spire being gently convex, whereas in B. hebera it is concave. The folds on the columella are more uniform in size and not grooved down the middle as in B. hebera. There are also differences in the spiral grooves of the anterior part of the shell. The same characters serve to distinguish this species from B. subhebera, Marwick, which has much more callus on the spire.
