Show 1891.] MR. E. A. SMITH ON SHELLS FROM ADEN. 405 34. MUREX HAUSTELLUM, Linn. Hab. Red Sea, Ctylon, Mauritius, China, Philippines. Aden (Caramagna). 35. MUREX (CHICOREUS) ANGULIFERUS, Lamarck. Hab. Aden (Jousseaume), Red Sea, Persian Gulf, Indian Ocean, Seychelles, Bourbon, Ceylon. In Cuming's collection is a shell, named M. lycacantha, Jonas (not cyacantha as given by Sowerby and copied by Tryon), which appears to be only a manuscript name. It evidently is the same as M. anguliferus. 36. MUREX (CHICOREUS) RAMOSUS, Linn. Hab. Red Sea, Indian Ocean, Polynesia, &c. 37. MELONGENA PARADISIACA (MARTINI), Reeve. Hab. Red Sea, Mozambique, Natal, Ceylon, Bourbon. The epidermis of this species is quite velvety to the touch and is covered with innumerable very short glossy hairs, disposed in longitudinal series upon the lines of growth ; they are invisible to the naked eye. The operculum is unguiculate, more than twice as long as broad, strong, thickened underneath along the outer margin, and has the nucleus terminal. 38. PISANIA TRITONOIDES (Reeve). Buccinum tritonoides, Reeve, Conch. Icon. vol. iii. pi. x. f. 77. Hab. Philippine Islands. I cannot agree with Tryon in considering this species a variety of P. iynea, Gmelin. The differences of form, colour, and sculpture are, I think, sufficient to separate them. 39. TRITONIDEA UNDOSA (Linne), var. Hab. Malacca, Australia, Philippines, Viti, Paumotus, Society Islands. This species varies considerably in size. The specimens from Aden are very small in comparison with the shell figured by Reeve1 from the Philippines, being only 22 millimetres in length. They differ also in the absence of the yellow margin to the aperture. 40. COLUMBELLA PROPINQUA. (Plate XXXIII. fig. 3.) Testa acuminata, ovata, solida, olivacea, interdum aurantia, et maculis albis fusco marginatis variegata; anfractus Iceves vel obsolete spiraliter striatic ultimus versus distinctius transversim striatus ; spira brevis, concave acuminata; apertura albida vel pallide ccerulea, angusta, longitudinis totius \ adcequans ; labrum extus incrassatum, intus denticulatum, denticulis medianis cceteris majoribus ; columella callo tenui induta. Longit. 16| millim., diam. 9. This species is very like G. vulpecula, Sowerby, but differs in 1 Con. Icon. vol. iii. Buccinum, pi. viii. fig. 55. |
