Type species: Perirhoe circumcincta (Deshayes, 1857); OD.
Diagnosis: Shell small to medium-sized (< 50 mm), solid; axial sculpture weak to obsolete; spiral sculpture of irregular punctate groves; subsutural band weakly defined.
Distribution: S Pacific, particularly New Caledonia.
Remarks: Perirhoe is close to the genus Oxymeris in terms of shell proportions; however, it can be readily differentiated from species of the latter by the distinct spiral grooves throughout the whorls’ height. The sculpture pattern of widely set spiral grooves in Perirhoe resembles that in some species of Terebra, but the latter group has notably more slender shells, with higher spire and less robust siphonal canal.
Included species:
Perirhoe circumcincta (Deshayes, 1857) 4;
