Show 1891.] MR- E- A- SMITH ON SHELLS FROM ADEN. 401 The shell described by Crosse under the name of C. mirmillo not allied to this species, with which it is united by Tryon (Man. Con. vi. 44), but should be regarded as a form of C. vulpinus. 14. CONUS CATUS, var. Conus coffea, Gmelin, is probably the same as this species. C. discrepans, Sowerby, also appears to be a variety; and C. adansonii, Reeve, and C. nigropunctatus, Sowerby, may be regarded in the same light. The specimens from Aden belong to the var. adansoni. Hab. Red Sea, Mauritius, Java, China, New Caledonia, Polynesia. Gulf of Akaba (Brit. Mus.). 15. CONUS ERYTHR^EENSIS, Beck. Hab. Red Sea. With this species may be united C. piperatus, Reeve (non Dillwyn), C. hamilli, Crosse, C. dillwynii, Reeve, C. induratus, Reeve, C. adustus, Sowerby, and C. quadratomaculatus, Sowerby. 16. CONUS TRAVERSIANUS, Smith. Conus traversianus, Smith, Quarterly Journ. Conch, vol. i. p. 107, woodcut; Sowerby, Thes. Conch, vol. v. p. 263, pi. 511. f. 719. The locality of this species has hitherto remained unknown. The two specimens from Aden answer in every respect my original description. The spire, as conjectured, consists of ten whorls, which are slightly turreted. Mr. Sowerby's figure gives but a poor idea of the beauty of this shell, the form being not sufficiently tapering anteriorly, the aperture too narrow, the transverse articulated lines are not indicated, and the blotched bands are not correctly placed. The figure in the ' Quarterly Journal of Conchology' represents the bands more accurately as regards position, but apparently they are generally more blotchy and broken up. The whorls of the spire also are slightly elevated one above the other, producing a turreted appearance. A specimen from Amboina has recently been presented to the Museum by Mrs. Parkinson. 17. CONUS ADENENSIS. (Plate XXXIII. fig. 1.) Testa elongato-turbinata, alba, seriebus macularum subquadratarum transversis, et zonis duabus aurantio-fuscis (altera supra medium infra) cincta, transversim sulcata; interstitia minus tuberculata ; spira breviter conica, leviter concava, aurantio-fusca maculata; anfr actus 12-13, levissime turriti, infra suturam marginati, declives, lirulis tenuibus spiralibus ornati; apertura angusta, intus alba. Longit 48 millim., diam. maj. 21^. The colour and disposition of the"markings are similar to those of C. planiliratus, Sowerby, from the China Sea, but the form is different, especially as regards the spire. It is a little more elevated |
