Phymorhynchus cingulatus, common name the ringed turrid, is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

The spiral sculpture consists of two sorts: first, a fine, sharp, slightly irregular striation, which covers the whole surface; secondly, of revolving elevated cinguli, of which three on the periphery are more widely and deeply separated and more elevated than the others.

On the body whorl in front of the periphery the cinguli are flat-topped little elevated wide bands with narrower interspaces, this sculpture becoming obscure toward the siphonal canal.

Above the periphery is one well-marked cingulum slightly turretting the whorl which inclines from it to the suture in a flattened manner.

The outer lip is very thin, sharp, crenulated by the outside sculpture, which also grooves the interior.
