Remarks
From Cleland (1907, p. 464): “Shell medium, sub-triangular in a longitudinal section. Transerve section oval or circular. Conch rapidly and regularly enlarging to the point of greatest transverse section, which is about midway between the last septum and the aperture of the chamber of habitation, thence contracting more gradually to the aperture.” Gomphoceras whitfeldi by Cleland in 1907.
