below the middle in the early whorls, above it in the later, 

 slightly adpressed below the linear suture. Body- whorl con- 

 cavely attenuate at the base. Aperture narrow elongate- 

 oval, ending in a moderately long open canal, which expands 

 slightly in front, bends a little to the left, and is barely re- 

 curved. Outer lip thick, sharp-edged, with a deep oblique 

 posterior sinus of three-quarters of a circle, having a thick- 

 ened reflected margin, and sejoarated from the base of the 

 whorl by a callous pad derived from the inner lip ; then 

 straightly convex, with a wide, very shallow excavation at 

 the base of the canal. Inner lip complete, applied, smooth; 

 columella long, nearly straight. Axial costse are oblique, 

 fading out above the angle, rounded, nearly as wide as the 

 spaces, ten in the penultimate, absent from the base. The 

 spiral lirse are crowded, fourteen in the penultimate, very 

 close-set on the base, granulated by fine accremental striae. 

 Colour in a fresh cotype is dull-white, with faint-brown 

 clouding between the ribs, and a faint-brown band above the 

 suture and round the periphery of the body-whorl. 



Dim. — Length, 186 mm.; of the body-whorl, 11 mm.; 

 breadth, 45 mm. 



Locality. — Type from 200 fathoms off Beachport. 

 Dredged also in 90 fathoms off Cape Jaffa, 1 very good, 1 

 poor ; in 104 fathoms 35 miles south-west of Neptune Islands, 

 10 good, immature, dead; in 110 fathoms off Beachport, 2 

 fresh, 3 good, 1 broken. 



Drillia trophonoides, n. sp. PI. xxvi., figs. 3 and 4. 



Shell solid, white, high, narrow, conical, with a blunt 

 apex and rounded base ; of 9|^ whorls, including a protoconch 

 of 2| convex whorls, the first two smooth, the rest faintly sub- 

 distantly axially plicate, ending abruptly. Spire- whorls con- 

 vex. Sutures distinct, subcanaliculate. Body-whorl short, 

 roundly contracted at the base. Aperture roundly oval, wid- 

 est behind, roundly contracted in front, constricted at its 

 junction with the canal. Outer lip sharp, simple, scarcely 

 inflected, convexly retreating from the suture to form a semi- 

 circular sinus, then convexly antecurrent to a very slight an- 

 terior sinus at the constricted neck of the canal. Inner lip 

 a thin, complete glaze ; base roundly concave ; columella 

 straight, curved to the left in the canal, and slightly thick- 

 ened on the outside of its anterior end. Narrow spiral cords, 

 one-third as wide as their interspaces, increase from four 

 in the first whorl to nine in the penultimate, and twenty- 

 three in the body-whorl, and are minutely roughened by sub- 

 lenticular accremental striae.
