1891.] MR. E. A. SMITH ON SHELLS FROM ADEN. 401 



The shell described by Crosse under the name of C. mirmillo is 

 not allied to this species, with which it is uaited by Tryon (Man. 

 Cou. vi. 44), but should be regarded as a form of C. vulpmus. 



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.

 Gulf of Akaba {Srit. Mus.). 



15. Conus ERYTHRiEENSis, Beck. 



Hab. Red Sea. 



With this species may be united C. piperatus. Reeve (non 

 Dillwyn), O. hamilli, Crosse, C. dillwynii. Reeve, C. induratus, 

 Reeve, C. adustus, Sowerby, and C. quadra tomficulaius, Sowerby. 



16. Conus traversianus, Smith.

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 articu- 

 lated 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 altera 

 medium infra) cincta, transversim sulcata ; interstitia plus 

 minus tuberculata ; spira breviter conica, leviter concava, 

 aurantio-fusca maculata ; an fr actus 12-13, levissime turriti, 

 infra suturam murginati, declives, lirulis tenuibus spiralibus 

 ornati ; apertura angusta, intus alba. 



Longit 48 millim., diam. maj. 2\\. 



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
