Austrofusus beta is an extinct species of medium-sized sea snail or whelk, a marine gastropod mollusc in the family Prosiphonidae.

Description

The shell stands 30 mm in height with a diameter of 17 mm.

(Original description) Distinguished from Austrofusus alpha by a tendency to stronger tuberculation, giving the peripheral keel a more angular aspect and the whole shell a broader outline; the spirals are less raised and have lost their regularity, three or four on the base becoming stronger and more prominent, and indicating a low second keel, while the three on upper keel are closer but hardly stronger than the others. Spire-whorls often slightly shorter than in previous species, with keel a little below middle.

Distribution

The marine species is endemic to New Zealand.
