in 40 fathoms off Beachport, 1 poor. Its habitat seems to 

 be mostly under 25 fathoms. 



Drillia jaffaensis, n. sp. PI. xxvi., figs. 7, 8, and 9. 



Shell turreted-oval, of 7 whorls, including the blunt proto- 

 conch of 2 smooth convex whorls, with a subimpressed suture, 

 ending abruptly. Spire-whorls convex, angulated in the 

 first and second below the middle, and at the middle in the 

 fourth ; with a subsutural threadlet in the first which enlarges 

 progressively to a stout round spiral ; in the second another 

 appears midway between the angulation and the lower suture ; 

 and in the fourth another below this ; in the fifth or body- 

 whorl two fine spirals appear above the angulation, and there 

 are thirteen below it, becoming fainter and lower anteriorly ; 

 they are much narrower than the interspaces ; the spiral just 

 below the suture, and that at the angulation are the most 

 valid, and are well nodulated, the nodules being somewhat 

 pliciform, directed downwards and backwards on the for- 

 mer, and downwards and forwards on the latter ; the next two 

 spirals are nodulated, but less so, also downwards and for- 

 wards. Axial lirse, starting from the suture, are directed 

 downwards and backwards to the nodules on the first spiral, 

 are then concave forwards between these and the nodules on 

 the angulation, and then run obliquely convexly forward to 

 the nodules on the next two spirals ; on these, by intercalated 

 lirae, the nodules are doubled in number, but are almost im- 

 perceptible on the spirals beyond. Body-whorl is rhomboidal, 

 concavely contracted at the base. Aperture squarely oval, 

 opening into a short, wide canal. Labrum thin, angulated at 

 the upper fourth, slightly crinkled by the spirals, pinched 

 in front to form the canal ; in profile it has a deep trigonal 

 sinus between the suture and the angle, is then convex, and 

 has a shallow excavation where the aperture is pinched. Inner 

 lip is a narrow glazed depression ; columella straight. Colour 

 white. 



Dim . — Length, 8'8 mm. ; of body-whorl, 5 mm. ; breadth, 

 35 mm. 



Locality. — Type from 130 fathoms off Cape Jaffa with 

 1 other ; in 104 fathoms off Neptune Islands, 8 good, 25 im- 

 mature or broken; in 110 fathoms off Beachport, 2 good; in 

 300 fathoms off Cape Jaffa, 2 very poor. 



Drillia achatina, n. sp. PI. xxvi., fig. 2. 



Shell solid, elongate-fusiform, of 6^ whorls, including the 



blunt protoconch, which merges into the spire insensibly. The 



first wliorl and a half are smooth and rather flat ; the next 



is scarcely convex, and has at first distant invalid axial angu-
