Primovula striatula traillii (= Crenavolva traillii) is characterized by 1) slenderly fusiform, convolute shell attaining 15 mm in height, 2) periphery subangular, widest at about the adapical one-third, 3) aperture narrow, somewhat twisted and flaring outward adapically, widening behind the abapical canal, 4) funiculum triangular, heavily callused, bearing 4 blunt ridges of decreasing length, 5) outer lip nearly flat and bent inward, 6) labial teeth relatively strong adapically, obsolete abapically, 7) fossula shallow, bounded by a keel and 8) dorsal surface with uneven, weakly incised spiral striation.

Crenavolva traillii is distributed in the tropical Indo-Pacific, from the Persian Gulf to Australia and the Philippines. Like other ovulids, it lives in association with coelenterates, feeding on the polyps (WILSON, 1993). FOSSIL RECORDS. None recorded.
