Rissoa hulliana var. eucraspeda Hedley, 1911 (superseded combination)

Alvania eucraspeda is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae. [1]

The Australian Faunal Directory considers Rissoa hulliana var. eucraspeda a synonym of Alvania (Alvania) fasciata (Tenison-Woods, 1876) [2]

Description

The length of the shell attains 2 mm, its diameter 1.5 mm.

(Original description) This deep-sea variety differs from the typical shore form by being pure white, slightly larger and comparatively broader, and by having fewer and more prominent radials. Thus it acquires a lip broader and more scalloped, approaching a varix. [3]

Distribution

The holotype of this species was found off Cape Wiles, South Australia.
