Caecum lindae sp. n.

Figs 15, 25K

Etymology: Named after Linda Davis, collections manager for Mollusca at NMSA.

Description: Tube subcylindrical, flaring towards the aperture. Aperture oblique, contracted, ending with three concentric rings. Septum protruding, with a strong, pointed mucro with subtriangular outline, slightly displaced toward the right side. Ventral side of the septum convex, dorsal one slightly concave. Early stages and operculum unknown. Length: 2.5 mm.

Type locality: SOUTH AFRICA: Eastern Cape: Agulhas Bank, off Cape Morgan Lighthouse, - 100 m.

Holotype (Fig. 25K): SOUTH AFRICA: Eastern Cape: dd, Agulhas Bank, off Cape Morgan Lighthouse, - 100 m, depth broken coral + shell from (NMSA W9682 / T3924), length 2.5 mm, min. diam. (posterior end) 0.39 mm, diam. in the middle of the tube 0.5 mm, max. diam. (apertural end) 0.56 mm.

Distribution: Currently known only from the type locality, Cape Morgan, north of East London (Fig. 15).

Remarks: Caecum lindae sp. n. shows a unique shape of the septum among South African species. It can only be compared with C. geigeri Pizzini & Raines, 2011, described from Austral Is., due to the similar shape of the septum, but it can be distinguished by the different shape of the tube and by the absence of the strong annulations preceding the aperture.
