Description.—Shell small, oval, a little higher than long, convexity small; somewhat inequilateral, the antero-dorsal border slightly concave and longer than the postero-dorsal, which is slightly convex. Ears very unequal. Apical angle from 95° to 100°.
Right valve flattened, nearly smooth, with faintly marked, nearly straight radial ribs near the anterior and posterior borders, separated by narrow punctate grooves; ribs and grooves absent or indistinct on the middle of the valve, except near the umbo. Anterior ear long, with a deep sinus, and three or four radial ribs crossed by growth-ridges. Posterior ear small, with its outer angle obtuse. Left valve rather more convex, with similar ornamentation. Measurements: Remarks.— This species differs from the typical Camptonectes in having the punctate grooves nearly straight instead of curving outwardly.
Types.— In the Woodwardian Museum, Cambridge. Distribution.-— Gault of Folkestone and Black Ven. HENRY WOODS, 1902

«Whether this species is really a separate species is difficult to decide on the limited number of available specimens, which are mostly poorly preserved.
The straight, punctae-bearing striae are indeed an unusual feature; it could also be that these specimens are slightly aberrant C. striatopunctatus (ROEMER). I am not quite convinced that the Ukrainian specimen belong to this species: the left valve mentioned by PASTERNAK is almost twice the size of the largest British specimen. Generic attribution: Since this species is very closely related to Camptonectes striatopunctatus (ROEMER), it seems logical that if Pecten gaultinus WOODS is proved to be a separate species it will certainly also belong to the genus Camptonectes and hence the correct name is Camptonectes (Camptonectes) gaultinus (WOODS).» DHONDT, A.
