Maoritomella is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae.[1]
Description
The small shell seldom exceeds 10 mm and has usually a fusiform-biconical shape. The axial riblets in the bluntly domed protoconch are absent or restricted to the terminal half-whorl. The sculpture consists of strong spiral lirae or cords with fine collabral threads crossing spiral lirae. It often contains a peripheral keel but never a conspicuous shoulder angle.The siphonal canal is not or feebly indented. There is an anal sinus on the shoulder slope. An operculum is present.The marginal teeth of the radula are rather short, straight and awl-like[2]
Distribution
This marine genus occurs off Indonesia, South Africa, Zanzibar, New Zealand and Australia (New South Wales, Queensland and South Australia).
