Notosinister: Triphoras with typical sculpture of three rows of gemmules, and a simple aperture in which the posterior canal is reduced to a subsutural slit or sinus; anterior canal short and open; columella pillar broad, the anterior margin of the aperture sometimes expanded into a narrow fold or spur which may reach or partially cross the columella. The protoconch begins as a smooth dome, a keel developing on the second or third whorl; white transverse sculpture may appear as minute threads. The whole protoconch may have from two to five whorls, and adult sculpture appears quite abruptly. TYPE SPECIES Triphora fascelina Suter, 1908.
