Cymatosyrinx is a genus of sea snails, marine gastropodmollusks in the familyDrilliidae.^[1][2]

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:^[3]Cymatosyrinx aclinicaTucker and Wilson 1933 (alternative combination: Cymatosyrinx lunata aclinica), Cymatosyrinx dorseyiCooke 1926, Cymatosyrinx limatulaConrad 1830 (synonyms: Drillia limatula, Pleurotoma limatula), Cymatosyrinx lunataLea 1833, Cymatosyrinx magnolianaOlsson 1916, Cymatosyrinx marianaPetuch 1988, Cymatosyrinx perpolitaDall 1890, Cymatosyrinx tiaraGardner 1948, Cymatosyrinx ziczacGardner 1948.

This genus includes the thin-shelled light-colored species, previously included in Drillia^[4]

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.^[5]
