suture impressed, the body-whorl ventricose, regularly tapered in front. 

 Aperture long, oblique, posteriorly deflected to the right. Outer lip not 

 thin, acute. Sinus near the suture, deep, with a thick rim. Inner lip 

 broad, thin. Columella flattened, with 2 obscure plications near the middle. 

 Canal short, wide, truncate in front. Sculpture: Protoconch of 1| whorls, 

 smooth. First adult whorl with 2 spiral threads on the periphery, 2nd with 

 10 sinuous axial ridges overridden by fine spiral threads. The succeeding 

 two whorls are similarly sculptured, the axial ridges and spiral threads 

 being more numerous. Body-whorl with low axial ridges, sinuous hear 

 the suture and becoming obsolete at the periphery, the whole over- 

 ridden by close regular spiral threads. Colour : Dark buff, a faint purple 

 spiral band on the lower edge of the spire-whorls. On the bodv-whorl 

 are sinuous brown marks near the suture. 



Height, 5-2 mm. Diameter, 2-2 mm. 



Variations from Type. — The colour varies from white to buff, most shells 

 being ornamented with a few irregular brown marks. 



Habitat. — Dead shells dredged in 10 m. to 30 m. on gravelly bottom off 

 Sunday Island. 



Zafra kermadecensis n. sp. Fig. 37. 



Description oj Type Specimen. — Shell broadly fusiform, apex obtuse. 

 Whorls 4|, with a flattened periphery, shouldered, suture deep. Aperture 

 narrow, rhomboidal, the outer and inner lips parallel, obliquely truncated 

 in front and behind. Outer lip with a broad and shallow sinus at the suture. 

 Inner lip distinct throughout, narrow and slightly thickened along its straight 

 central and anterior portion. Canal short, wide. Sculpture : Protoconch 

 of 1 whorl, smooth. Shell with low rounded axial plications, about 15 on 

 each whorl. Base of body- whorl with several oblique plications. Surface 

 of shell smooth and shining. Colour : Protoconch white. Shell glassy, 

 tinged with yellowish. A spiral row of rectangular light yellowish-brown 

 patches on the spire-whorls, one on each alternate plication, and extending 

 from above the periphery to the lower suture. This row is continued on the 

 periphery of the body-whorl. Below it is a clear spiral band, the base 

 being more or less coloured with the same yellowish-brown. Tip of canal 

 clear. 



Height, 2-3 mm. Diameter, 1 mm. 



Variations from Type. — In some specimens the clear bands above and 

 below the periphery of the body- whorl are ornamented with semicircular 

 brown markings, with their convexity directed towards the aperture. 



Habitat.— Dead shells abundant in dredgings on gravelly bottom in 

 10 m. to 30 m. off Sunday Island. 



Zafra fuscolineata n. sp. Fig. 38. 



Description of Type Specimen. — Shell broadly fusiform, truncate in front, 

 apex obtuse. Whorls 5, flatly rounded, suture impressed. Aperture 

 oblong, slightly produced in front, outer edge nearly straight, inner edge 

 angled above. Outer lip thin, sinus at the suture, shallow. Inner lip 

 thickened, straight below. Canal short, wide. Sculpture : Protoconch of 

 1J whorls, smooth. Adult whorls with low, slightly oblique, axial ridges, 

 about 15 on the penultimate whorl, and becoming obsolete on the peri- 

 phery of the body-whorl. Interstices very shallow, concave. Base with 

 oblique grooves. Over the whole shell there appears under the microscope
