TYPE MATERIAL. — Holotype (lv) MNHN 20587 About MNHN and 2 paratypes (lv and dd) MNHN 20588 About MNHN .
TYPE LOCALITY. — Southern New Caledonia, 22°44’S, 167°17’E, 350-393 m [BATHUS 2: stn DW 717] GoogleMaps .
MATERIAL EXAMINED. — Southern New Caledonia. BATHUS 2: stn DW 717, 22°44’S, 167°17’E, 350-393 m, 2 lv and 1 dd (holotype, Fig. 10 and 2 paratypes, Fig. 11); stn DW 724, 22°48’S, 167°26’E, 344-358 m, 1 lv, 8 dd GoogleMaps .
DISTRIBUTION. — Southern New Caledonia, live and shells in 350-358 m.
DESCRIPTION. — Shell slender, cylindrical, solid, subtranslucent. Protoconch paucispiral, small. Spire short, pointed. Aperture long, narrow, subvertical. Base moderately tapering. Outer lip thick, rounded, stepped, upper part of inner edge wrapping up inside the aperture, lower part moderately excavated, with 7 small sharp denticles much smaller than the interspaces, 5 of them along upper part of inner edge, 2 below. Four thin, oblique columellar plaits, uppermost one smaller than remainder.
Ground colour porcellaneous white with 2 narrow orange spiral bands at top of last whorl and 2 over lower part, the 2 intermediate ones interrupted. Anterior part of the ventral side, at left of columellar plaits, orange. Top and base of outer margin deep orange.
Dimensions: 5.15 x 2.60 mm.
Radula unknown.
REMARKS. — Serrata quadrifasciata seems quite variable, one of the paratypes (Fig. 11) having a narrower spire, a more sloping labial shoulder and a straighter, non-reflected inner labrum. In its other features, including the number and shape of labial denticles and the pattern of the columellar plaits, it seems to be very constant. The most closely similar species are S. summa and the next species.
ETYMOLOGY. — Latin quadri - (substantive, of four) and fasciata (adj., encircled by a band), referring to the decoration of 4 spiral bands.
