CONTRIBUTIONS TO KNOWLEDGE OF MARINE MOLLUSCA 33 nodular; extremely fine and faint spiral striae between ribs, chiefly visible in the sulcus near suture; upper part of base smooth, lower part with 6-7 lirae; sulcus slightly concave between ribs; lip sinus deep, adjoining suture. 6x2-5 mm.; both the Zululand specimens slightly larger, with 3^-4 whorls 17x3 mm. Pale buff. Off Umhloti River (Natal), 40 fathoms, 2 unworn and one apex; off O'Neil Peak (Zululand), 90 fathoms, 2 worn (S. Afr. Mus. A8724, A8725, Coll.). Described from the unworn Natal specimens (A8724). Drillia morgana n. sp. Fig. 16 Aperture 1 \ in spire. Protoconch 2 whorls, nucleus depressed, alt. o-8, diam. 1 mm., smooth, junction with 1st postnatal whorl distinct. Postnatal whorls 3 J, profile evenly convex, sutures rather deep. Axial ribs 15-16 on 1 st, 19 on 2nd, c. 25 on 3rd whorl, narrow, not conspicuous, on last whorl sometimes coalescent (making an exact count difficult), crossing the undefined sulcus. No spiral sculpture except c. 10 lirae on lower part of base. 7-5 X 3 mm. Creamy white. Off Cape Morgan, 47 fathoms, one dead (S. Afr. Mus. A8739, Coll.). Drillia oneili n. sp. Fig. 15 c Aperture slightly less than spire (protoconch incomplete). Protoconch 2 whorls, apex corroded (but only the nucleus seems to be missing), smooth. Postnatal whorls 4, profile convex, scarcely any shoulder. Axial ribs 11 on 1st whorl, 12 on 2nd and 3rd, 13 on 4th, slightly oblique, rounded, about as broad as intervals, crossing sulcus but not the cingulum, petering out on base; crossed by narrow spiral lirae (on 1st whorl?), 2 on 2nd, 3 on 3rd and 4th, c. 14 addi- additional lirae on base; in addition very fine spiral lirae over whole whorl, c. 6 in sulcus on 4th whorl. Sulcus not concave, with narrow but distinct cingulum. Lip sinus deep, adjoining suture. Growth-lines very faint, not forming any cancellatio
