If my memory does not fail me, Abbott illustrates both species, concinna
and cincinniformis (both Sowerby, 1841).  Concinna is from the Romblon
Province, just north of Panay Island and cincinniformis is endemic to
Lubang Island, off the west coast of Mindoro Island.  The major difference
between the two is the shape.  Concinna is more slender with a 'pointier'
apex.
