Remarks.

No material of this species was found, and only the type specimens were examined. The generic placement of this species is provisional. We placed this species into Macrochlamys s.l. because it has a depressed conic shell, thin and translucent shell, smooth and shining shell surface, with 4 to 7 whorls and the last whorl rounded, and a simple apertural lip. However, this species differs slightly from Macrochlamys s.l. in having varices and a widely opened umbilicus (see Godwin-Austen (1883: 76-84) and Blanford and Godwin-Austen (1908: 77-79) for further comparison).
