Rissoa similis
Description A. Verduin: « The lower two or three whorls of the great majority of the shells are uniformly covered with punctate spiral striae, which also cover the base of the shell. In ribless shells this sculpture may be weak or absent. Such shells may be easily mistaken for R. parva forma interrupta (Adams,1798). »In this form, the shell, more or less slender, is often adorned with suprasutural and subsutural flamules ("interrupted"). Generally weak and thin, almost obsolete in some specimens, the spiral striae become stronger near the suture and at the base. Anse Bernardi, Port-Vendres, Eastern Pyrenees, S. France. 2,75mm. Raymond Huet legit.
