''Pusionella buccinata'' is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae. Found by Lamarck in 1822.

Pusionella Compacta
''Pusionella compacta'' is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae. Description The shell grows to a length of 26 mm.

They occur only up to the 7th whorl yet and then disappear completely, and as otherwise deviations also occur, so this form must be singled out. The compact spire contains 11–12 whorls. These are slightly rounded and convex. The aperture is the same as in ''Clavatula milleti''. The callus at the anal sinus stands out clearly. Distribution This species occurs in the Atlantic Ocean off West Africa and Angola Angola, officially the Republic of Angola, is a country on the west-Central Africa, central coast of Southern Africa.
