MOLLUSCA. 77101. Haliotis (Teinotis) asinina, Linn.Hah. Port Molle on coral-reef.A single jouiig specimen was collected, having but five perforationsopen. Tlie two nuclear whorls are fleshy pink and smooth,and the radiating ridges are beset with fine granules alternatelytilrquoise- blue and scarlet.102. Dentalium javanum.Sowerbi/,Thes.Conch. vol. iii, p. 102, pi. 223. fig.l2 ;Conch. Icon. fig.l4.Hab. Java (Sowh.) ; Malacca, coarse sand, 12 fms. (Cuming inBrit. Mus.) ;Port Darwin, 8-12 fms., sand and mud {Coppinger).This species is very nearly related to D. octogomun of Lamarck.The eight ridges are conspicuously acute, the interstices beingflattish, and marked only with cross lines or striae of growth. Thecolour of this shell is white, varying to pale green.103. Scutus unguis.Patella unguis, Linn. Syst. Nat. ed. 12, p. 12G0(part.) ;Ilanley, IpsaLinn. Condi, pi. 3. fig. 4.Hah. Flinders and Clairmont Islands, N.E. Australia, 11 fms.{Coppingi;r), also Thursday Island.For full synonymy of this species I would refer the reader to apaper by the author on this genus in the 'Journal of Conchology,' vol. ii.pp. 252-264. The animals from the above locality are yellowish or,buif, copiously blotched and stained irregularly with blackish grey,104. Fissurella jukesii.Reeve, Conch. Icon. fig. 45 (only half-growu).Juv. = F. fimbriata, Reeve, Conch. Icon. fig. 104.Hah. Port Darwin, N.W. Australia {Coppinger) ; Port Molle,Queensland (Jid-es).•This species may be recognized by the elevated squamous characterof the radiating ridges, which are more or less tinted with pale rose.In the young state the apex is more conical than in older shells, andthe foramen (as is usually the case in immature specimens of thisgenus) is more central.105. Fissurella singaporensis.Reeve, Conch. Icon. figs. 100, 101.the sole of the foot being of a uniform buff tint. The shells are ofthe same width (13 millim.) ;but one of them is 2o millim. long, theother only 23|, which gives to the former a more elongate appearance.Hah. Port Molle, Queensland, coral-reef, Port Curtis beach, andPort Darwin, N.W. Australia, 8-12 fms. (dead) {Coppinger) ; Singapore{Reeve).This form is allied to F. ticaonica, but may be separated on
