(Plate LXXV. fig. 12.) Testa ovata, alba, polita; spira acuminata, sutura chorda cincta; anfract. 5, convexi, spiraliter sulcati; in anfract. sulci 10; apertura pyriformis; columella callosa triplicata; labrum extra valide incrassatum. Long. 2|- mill., diam. maj. fere 2. Hab. Whydah. This minute species belongs to the same striated group as R. pro-pinquans, Hinds, from the Philippines and R. someri, De Folin, from the Cape-Verd Islands. Its much smaller size, the number and position of the teeth, and the callous chord around the suture of the whorls well distinguish it. 57. TRITON SAMIER, Adanson, Voy. Senegal, p. 122, t. 8. f. 1. Hab. West Africa. 58. NATICA COLLAEIA, Lamk. Anim. s. Vert. ed. 2, vol. viii. p. 638. Hab. West Africa, Whydah. 59. NATICA SAGRAINA, D'Orb. Moll. Cuba, pl. 18. f. 20-22. Hab. Whydah. I have compared the shells which I refer to this species with the typical specimen in D'Orbigny's collection of Cuban shells in the British Museum, and find that they are identical; therefore this species appears to be found in the Mediterranean (Malaga), Reeve (Con. Icon. ix. sp. Ill), West Africa (Whydah), Knocker, and West Indies (Cuba), D'Orbigny. 60. NATICA MAROCHIENSIS, Lamk. Anim. s. Vert. ed. 2, vol. viii. p. 642. Hab. Whydah. " Morocco and West Indies" (Lamarck and Reeve, Conch. Icon. ix.). 61. NATICA RUBRO-MACULATA, sp. nov. (Plate LXXV. fig. 13.) Testa globosa, leevis, umbilicata; spira breviuscula ; anfract. infra suturam leviter depressi et oblique sulcati, leviter undulatis et maculis subquadratis remotis rubris (in anfr. ult. trifasciatim) ornati; columella Alt. maj. 15 mill., diam. maj. 15. Hab. Whydah. A very distinct solid species, longitudinally lined, and with three interrupted bands of squarish reddish spots encircling the last whorl; these bands are sometimes altogether absent, and sometimes there are but one or two. |
