''Finella pupoides'' is a species of small sea snail, a marine gastropod mollusk in the family Scaliolidae. ==Description== The shell size varies between 2 mm and 4 mm. Its color varies from white to pale yellow, a few times even dark brown. The shell shows typically two indistinct brown bands below the suture and at the base. The shell is elongate, fusiform with a narrow, pointed apex. This protoconch is smooth and contains about 2.5 whorls. The whorls are rather inflated and have deeply marked sutures. The sculpture of the teleoconch has characteristic flat-topped spiral cords with rather weak axial ribs. These form a fine reticulate pattern on the upper whorls. This axial sculpture is reduced to absent on the body whorl. The aperture is semicircular. The narrow columella is curved. 〔 ( Hasegawa K., 1998.
