Comitas thisbe is a species of sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, the turrids and allies.

The chief characteristics of this species, represented by a unique specimen, are the smooth concavity at the upper part of the remaining whorls, exhibiting only very delicate lines of growth and faint traces of spiral striae, the numerous slender oblique costae upon the lower two thirds of each whorl, and the distinct close wavy striae on and between the ribs.

These are nineteen in number upon the penultimate volution, thickest at their upper ends, obliquely curved, attenuated below, and only just reach to the suture.

The broadly capacious body whorl is, excepting in the concavity above, delicately wavy striated throughout.

It is excavated over the neck to a slightly flexed, rather short, unnotched anterior canal.
