Compsodrillia catherina is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies. It was alive during the 2nd and 3rd periods of the Cenozoic Era (Neogene and Quaternary).
The length of the shell attains 7.8 mm; its diameter 2.9 mm. Although there are no photos that explicitly depict Compsodrillia catherina, based on the appearance of related species, we can conclude that it most likely had a pointed, spiraled shell and was orange and/or brown in color.
Fossils have been found in Pliocene strata of the Bowden Formation of Jamaica; also on Saint Thomas; age range: 3.6 to 2.588 Ma
