“Vexillum (Latriomitra?) problematicum n. sp. Plate 4, figs. 55, 56.

 

Shell large for subgenus, yellowish-white, with strong axial ribs crossed by fine spiral threads. Spire as tall as aperture plus canal. Teleoconch of seven whorls, convex; protoconch damaged, minute, smooth. Axial ribs heavily rounded, interspaces as wide as ribs, reaching from suture to suture but not over lower part of base. Spirals fine, close together, becoming a little more prominent on canal. Aperture broad, with four plaits uppermost very weak. Middle two strongest, lowest rather weak. Canal twisted to left and behind, broadly open and rather long.

 

Holotype: 33.2 × 12.15 mm. (Dominion Museum, Reg. No. M.21553).

 

Locality: Portobello Marine Biological Station Mu. 66-59 East of Taiaroa Heads, 45º50’S, 170º57’E in 65 fathoms.

 

The generic and subgeneric placing of this species is only tentative as comparative material and radula data are lacking.”
