''Skenea trochoides'' is a species of sea snail, a marine gastropod mollusk in the family Skeneidae. G.W. Tryon thought this species was a synonym of ''Cyclostrema peterseni'' Frielle, 1877 (now a synonym of ''Skenea peterseni'' (Friele, 1877)) 〔 ==Description== The size of the shell varies between 2 mm and 3 mm. The white shell is perforate, somewhat solid. It is opaque, smooth, and shining. The base of the shell contains sometimes a few faint oblique, curved lines;. The four whorls are convex and have a deep suture. The columellar lip is vertical, forming a slight angle with the outer lip at their junction.〔(G.W. Tryon (1888), Manual of Conchology X; Academy of Natural Sciences, Philadelphia ) (described as ''Cyclostrema trochoides'')〕
