FIG. 7. A, Typhinellus occlusus ( Garrard, 1963) , Fiji, MUSORSTOM 10 CP 1364, h 14.9 mm. B, D, Prototyphis gracilis n. sp., Fiji, BORDAU 1 CP 1394, holotype MNHN 20010, h 23.5 mm; C, protoconch. Scale bar 0.5 mm; E, adapertural side of wing.

MATERIAL EXAMINED. — Fiji. MUSORSTOM 10: stn CP 1364, 18°12’S, 178°35’E, 80-86 m, 1 lv .

DISTRIBUTION. — Philippines (Springsteen & Leobrera 1986: 131), Queensland (type locality), live in 31-200 m, and Fiji (new record), live in 80-86 m.

REMARKS. — The varices of Typhinellus are constricted above the aperture and flaring at the abapical end; the varical flange of the last teleoconch whorl extends to almost the tip of siphonal canal; the anal tubes are situated near the preceding varix, adpressed to the preceding partition. Typhinellus occlusus is easily distinguished by its narrow last teleoconch whorl, narrow aperture and very broad varical flange.
