Original Description of Pterocera fittoni by Forbes, 1845, p. 351:

• "P. testa brevi, crassa, anfractibus 6, spiraliter striatis, superioribus 3-carinatis, ultimo 8-carinatis, carinis duabus majoribus, crenulatis, labro quadridigitato, digitis linearibus, arcuatis."
• "Body of the shell ovate, ventricose with a spire of 5 whorls, all finely striated and ribbed spirally. The ribs on the upper whorls are few and nearly equal; those on the body whorl are numerous and of various dimensions; two corresponding to the anterior digitations of the lip are very strong, prominent, and crenated. A strong rib also runs between them. The lip is much dilated and is furnished with 4 digitations, the two anterior free, the two posterior attached, that above to the spire, and the lower one to the canal. The superior digitation is very long, linear, and curved, and exceeds the spire by half its length. The canal is also linear and curved. In all specimens the anterior digitations are imperfect."
