The following species have also been found as fossils in the United States and/or in Mexico in the age range: 37.2 to 0.012 Ma:^[2] Cymatosyrinx aclinica Tucker and Wilson 1933 (alternative combination: Cymatosyrinx lunata aclinica), Cymatosyrinx dorseyi Cooke 1926, Cymatosyrinx limatula Conrad 1830 (synonyms: Drillia limatula, Pleurotoma limatula), Cymatosyrinx lunata Lea 1833, Cymatosyrinx magnoliana Olsson 1916, Cymatosyrinx mariana Petuch 1988, Cymatosyrinx perpolita Dall 1890, Cymatosyrinx tiara Gardner 1948, Cymatosyrinx ziczac Gardner 1948.

Description

This genus includes the thin-shelled light-colored species, previously included in Drillia ^[3]

The shell is generally short and stout, the spire often very short. The whorls contain nodulous axial ribs, extending over the whole of the volutions. They are generally without spiral sculpture, or, if present, very weak. The aperture is subrhomboidal, very little narrowed below, with a short and broad siphonal canal. The outer lip is arched, with a shallow sinus towards the suture. The inner lipis large and callous.^[4]
