Description

Shell minute, white, semi-transparent, fragile. Whorls 4, including a typical large smooth dome-shaped protoconch of 2 whorls. The species is almost a miniature of the genotype, suteri, in style and spiral sculpture, but differs in having a proportionately larger and projecting D-shaped aperture and crowded distinct axial striae between the spiral keels. Anomala is only half the height of suteri, yet it is obviously adult.

Height, 1·4 mm.; diameter, 0·9 mm. (holotype).
Holotype in Auckland Museum.
Locality: Tom Bowling Bay, Northern New Zealand (in shell sand).
