Cymatosyrinx

Cymatosyrinx lunata, from Neogene Atlas of Ancient Life.

Belongs within: Drilliidae.

Cymatosyrinx is a genus of moderate-sized conoids with a high-spired, glossy shell found in the American tropics (Powell 1966).

Characters (from Powell 1966): Shell of moderate size, 10–45 mm, typically solid, with a tall spire and a truncated body-whorl, terminating in a short, twisted, very deeply notched anterior canal. Protoconch papillate of two smooth whorls, the first rather bulbous, with a lateral tip, the next with a low-set peripheral carina. Adult sculpture firstly a strong subsutural fold, which is nodulose where it overrides the axials, then a narrow deep shoulder sulcus, followed by strong very oblique broadly rounded axials, which extend below the lower suture and over the base to a deeply incised stromboid notch. Below this is another sulcus, crossed by diminished axials, to a prominent ridge margined anterior fasciole. Whole surface smooth and polished, without or with a minimum of spiral sculpture. Aperture ovate, outer lip widely flared but not variced. Sinus deep, U-shaped, on shoulder sulcus and somewhat constricted at entrance by a massive entering parietal callus pad. Radula prototypic, with minute vestigial central tooth, comb-like laterals, and long, slender, simple-pointed marginals, overlaid basally by small narrow member.
