Original Description of Aporrhais Mantelli by Gardner, 1875, p. 202:

• "Shell elongated, spire composed of convex whorls, ornamened with 12 or more regular, rather oblique, transverse ribs, extending the whole breadth of the whorls. Last whorl destitute of keel. The wing is broad, angular, and quadrate, prolonged posteriorly into a point, beneath which is a deep sinus, succeeded by a broad, quadrate expansion, which expansion is also frequently prolonged into a point, parallel to the first, truncated at its outer margin. The mouth is narrow, porcellanous; the anterior canal moderately long and straight."

Stratum typicum: Grey Chalk of Dover, (Upper Cenomanian(?)), Cretaceous
