Fusus buccinatus Lamarck, 1822 Pusionella compacta is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae.

[1][2] The shell grows to a length of 26 mm.

(Original description) This form differs from the group of Clavatula milleti (synonym: Pusionella milleti) in her characteristic feature of the sculpture: the continuous vertical spiral suture is missing.

The callus at the anal sinus stands out clearly.

This species occurs in the Atlantic Ocean off West Africa and Angola.
