Ad. differs from M. africana by its more acutely saddle-shaped form and by its very different shape ; thus a typical South Australian example measures 25 x 8, and another 24 x 8. Gen. Emarginula Lamarck. The first and only record of this genus from South Africa will be found in Ann. Natal Museum, vol. ii, pt. ii, p. 209, where Smith records from Tongaat E. micans A. Adams, which was originally described from Kains Island. I have not seen this Tongaat shell, but from the explanations necessary to fit it into micans one is very much tempted to suspect that it will eventually prove distinct. The following fine deep-water species is not a perfect shell, but the sculpture is so very clear, fresh, and perfect that there can be no difficulty in recognising it again with the aid of the excellent photograph now given. Emarginula pulchreclathrata n. sp. A fine species, somewhat similar in size and form to E. sicula Gray from the Mediterranean and to E. superba Hedley from Tasmania, but differing from both in sculp- ture. The South African shell has a series of alternately stronger and weaker ridges radiating from apex to margin, crossed nodosely by con- centric threads ; both stronger and weaker ridges vary somewhat in degree, and as a rule the weaker ones first appear some little dis- tance below the apex ; the whole arrangement constitutes a very marked and beautiful piece of lattice-work. The apex is bent over to form a small hooked beak. Long. 19 mm. ; lat. 12-5 mm. Hab. off Saldanha Bay in 55 fathoms ( Mus., No. A3617).. Fig. 4.—Emarginula pulchreclathrata n.
