• Anchura? monmouthensis Gardner

Sohl, 1960, p. 205:

• "Species questionably assigned to Drilluta: ... Anchura? monmouthensis Gardner, Monmouth Formation of Maryland ... Anchura? monmouthensis Gardner (1916, p. 476) the second questionably assigned form, is based on an internal mold that bears the impression of a columellar plication impressed on the interior of the whorls of the spire. This obviates the possibility of its belonging to Anchura and its size and reflection of coarse transverse ornament is highly reminiscent of the specimens assigned to Fasciolaria? sp. by Gardner."
