comparatively narrow depression; aperture slightly oblique, oval, E 
notched below ; outer lip convex, thickened above but thin below and with 
denticle opposite spiral depression ; columella slightly concave, trunca

Locality.—1104, Le Fossil Crede" A d of Cottage Road, Maraekakaho. 
Remarks. — This species was confused by Suter with A. depressa (Sowerby) 
because of its squatness, but it is comparatively much broader than that 
species. 
Marginella (Glabrella) brevespira n. sp. (Plate 17, fig. 6.)

shining ; че long, slightly wider below ; outer lip thickened; varix 
ascending to top of penultimate whorl, inside obsoletely toothed ; columella 
with 4 strong oblique folds, the lower two more oblique than ‘the upper.

narks.—This shell is closely related to M. kirki Marwick, but may 
be distinguished by the pp convex outline of the body-whorl and the 
very short spire with flat sides
