Scaphella robusta: S. marionae (Pilsbry and Olsson, 1953) (type locality: Gulf of Mexico) is a synonym according to Poppe and Goto (1992: 150). Scaphella worki Coltro, 1998 (type locality: Mississippi Fan off Louisiana, 366–457 m) is clearly a synonym of S. marionae and so presumably is a synonym of S. robusta. Coltro did not compare his new species to S. marionae, distinguishing it from S. robusta on the basis of its smaller size and recurved siphonal canal. The holotype of S. marionae (ANSP 189920) shares these features: 45.3 mm vs. 44.6 mm for the holotype of S. worki and 119 mm for the holotype of S. robusta; it also has similar spiral sculpture and nodules on the shoulder [GR].
