Stomatia cumingii: Chenu 1959 in 1959–62: 364, fig. 2709.

This species is similar to Granata sulcifera (below) and does not warrant a full redescription. It differs most obviously in shape and colour, having a distinctly more elongate aperture (ratio of maximum:minimum aperture diameter 1.25–1.40 in G. cumingii compared with 1.04–1.16 in G. sulcifera ) and a more consistent colour pattern of reddish or reddish brown spots on a cream ground that remain distinct even on the last adult whorl. In addition, the sculpture of G. cumingii is somewhat coarser, the axial pliculae more crispate and regular, and the interstices more obviously iridescent. Although smaller, the three specimens listed below, are almost identical with the holotype and are undoubtedly conspecific therewith.

Besides mention in late nineteenth century iconographies ( Sowerby 1874; Pilsbry 1890 in 1890–91), this species seems not to have been discussed in the literature subsequent to its original description. No locality data accompanied the holotype and, until now, the provenance of the species has remained unknown. Granata lyrata (Pilsbry, 1890) , from Japan, which is also reportedly more strongly sculptured than G. sulcifera (Sasaki 2000) , as a less elongate aperture and has greyish rather than reddish maculations.

Microsculpture: Similar to that of G. sulcifera .

Protoconch: Missing in all available specimens.

Operculum: Oligospiral; like that of G. sulcifera .

Radula: Unknown.

External anatomy: Only one, badly contracted specimen available, but evidently similar to that of G. sulcifera .

Type material: Holotype of Stomatella cumingii A.Adams, 1854 , in NHMUK (1968201), maximum diameter 31.1 mm, height 19.8 mm ( Fig. 63 View Fig ); provenance unknown.
