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.

''Pusionella rapulum'' is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae. Description The oblong shell is ovate The whorls are compressedly gibbous, forming a round shoulder, constricted and with revolving striae towards the base. Otherwise, the shell is smooth, except that the upper whorls of the spire are slightly longitudinally plicate. The color of the shell is whitish, under a very thin, smooth, yellowish brown epidermis.
