TYPE MATERIAL - Holotype MNHN IM-2000-6775 (as listed below). TYPE LOCALITY-Makassar Strait, 00°31'N, 117°50'E, 595 m [CORINDON 2: stn CH214]. 384 Koen Fraussen & PETER STAHLSCHMIDT MATERIAL EXAMINED Indonesia. CORINDON 2: stn CH214, Makassar Strait, 00°31'N, 117°50'E, 595 m, 1 lv (holotype MNHN IM-2000-6775; Fig. 70). Papua New Guinea. BIOPAPUA: stn CP3703, 03°53′S, 144°41′E, 361-750 m, 1 dd.
DISTRIB.Known only from the holotype from Indonesia and from Papua New Guinea;alive in 595 m.
REMARKS-Manaria makassarensis is characterized by its rather short spire (aperture with siphonal canal more than half of total shell height), the rather narrow aperture and the spiral sculpture with alternating fine and wide, flattened spiral cords on the whorl sides, the finer spiral cords on the base, in combination with weak, narrow but sharp axial ribs on the spire whorls. The radula was figured by Bouchet & Warén (1986: pl. 4, fig. 24). Manaria brevicaudata (Schepman, 1911) is quite similar in sculpture to M. makassarensis and some broader specimens resemble M. makassarensis closely, but it differs in the smooth subsutural slope of most specimens, the irregular spiral sculpture (rather than regularly alternating fine and wide cords), the wider aperture and the shorter siphonal canal. Manaria terryni n. sp. possesses similar sculpture to that of M. makassarensis on the lower spire whorls, but differs in the more slender shape with a higher spire, and the angulate upper spire whorls.
