While this species resembles typical Nomura, 1939; Hoonsvrnota Nomura, 193S; Odostomia, it has palatal ridges within the outer lip. Marginodostomia Nomura, 1936; Menesthelta This suggests placement in Megastomia Monterosato, Nomura, 1939; Mormurella Nomura, 1939; 1884.

Anatomical Nomura, 1939; Rissosyrnola Nomura, 1939; studies by Hori (unpubl.) show fundamental contrasts Sinuatodostomia Nomura, 1937; and Siogamaia between Megastemia and Odostomia. Thus Nomura, 1936. Megastomia is here ranked as a fu11 genus. Three of these 13 names pose subjectiye or inter- pretive problems. Mermurella is probably an epitoniid 71trbonitla dioflelix nom. noy. <Makiyama, 19S8).
