Type material. Holotype — NMB H16578. The type measures 21.4 mm in length, with a width of 7.3 mm ( Jung 1974).

Type locality. Monte Grumi , Castelgomberto, Italy [Oligocene] .

Diagnosis. The shell is moderately slender with a moderately acute apex. The labium is thin and continues above the adapical end of the aperture to the apex. The labrum is thin but thickens forming a posterior canal. The columella is basally slightly bent backward.

Distribution. OLIGOCENE— Italy Monte Grumi, near Castelgomberto ( Jung 1974); Santa Trinità, near Mon- tecchio Maggiore ( Jung 1974).

Remarks. A small Seraphs similar to S. chilophorus , but the shoulder of that species is more defined, and there is no reabsorption of the shell behind the posterior canal in S. chilophorus ( Jung 1974) .
