DESCRIPTION. — Shell up to 27 mm long, solid, shiny, cream, straight for the anterior 3/4, gently curved at posterior end. Section subcircular throughout, compressed dorsoventrally. Sculpture of 11 smooth prominent primary ribs, stronger on dorsal than on ventral side. Intercostal spaces smooth. A few secondary ribs originate on posterior 1/3 of shell, not reaching the prominence of the primary ribs, all vanishing near a fragile oral aperture. Apex narrow with V-shaped notch on ventral side. Measurements of holotype : L 27, W 2.6-2.3, w 0.50-0.48. REMARKS. — This species is related to Compressidentaliulm ceciliae Scarabino, 1995 , but has fewer ribs (primary and secondary) and even in well preserved specimens the ribs do not reach the mouth. The shell outline is more irregular, less compressed, and the anterior area is smooth. It is also similar to Dentalium oryx Boissevain, 1906 , but that species has a circular section throughout. ETYMOLOGY. — Named after Jerry Harasewych (USNM).
