■100 MR. E. A. SMITH ON SHELLS FROM ADEN. [JuDC 16, 



6. CONUS BETULINUS, Linii. 



Hab. E. Africa, Isle of Bourbou, Ceylon, Java, China, Philippines. 

 Aden (Caramagna). 



I do not agree with Tr)'ou' in considering C. suratensis a variety 

 of this species. 



7. CoNus STRiATUS, Linn. 



Hub. Red Sea, E. Africa, Ceylon, Cochin China, Philippines, 

 Australia, New Caledonia, Viti Islands. Ainirantes, Solomon 

 Islands, Island of Annaa(ifnY. Mus.). 



8. CoNUS GENERALis, var. 



Hab. Red Sea, Ceylon, E. Africa, Philippines, New Caledonia, &c. 



C. maldivus, Hwass, C. monile, Hwass, and C. bayani, Jousseaurae, 

 should, I think, be considered varieties of this species, and O. spiro- 

 gloxus, Deshayes, appears to be the young of it. One of the 

 specimens from Aden is like Reeve's figure of C monile (Con. Icon, 

 f. 61), but the transverse lines are not interrupted and very much 

 finer and thread-like. A second young example has equally fine 

 lines, but they are interrupted and consequently form series of dots. 



9. CoNUS ACUMiNATUs, Hwass. 



Hab. Red Sea. 



C. insignis and C. multicatenatus, Sowerby, belong to this species. 

 The latter is placed by Tryon among the synonyms of C. aplustre, 

 Reeve. Having Sowerby's type in the Museum, I am able to state 

 that it bears no relationship to that species. 



10. CoNus VIRGO, var. thomasi, Sow. 



Hah. Red Sea, E. Africa, Ceylon, Amboina, Java, Philippines, 

 New Caledonia, Polynesia. Fiji, Tongatabu (Brit. Mus.) ; Aden 

 (Caramagna). Only the variety (thomasi) is among the Aden 

 shells. 



11. CoNUS FLAViDus, Lamarck. 



Hab. Red Sea, Persian Gulf, E. Africa, Ceylon, Java, Australia, 

 New Caledonia, Polynesia. Mozambique, Island of Rodriguez, 

 Torres Straits, Solomon Islands, Fiji and Tonga Islands (Brit. Mus.). 



12. CONUS INSCRIPTUS, RcevB. 



Hab. Red Sea. 



C keatii, Sowerby, from the Seychelles Islands, which apparently 

 is- only a variety of this species, has the spire sligiitly tabulated and 

 the tops of the whorls have more numerous spiral striae. One of 

 the six specimens from Aden possesses these characteristics. 



13. CoNtJS LiNEATUS, Chemnitz. 



Hab. Red Sea, East Africa, Ceylon, Philippines, Australia, New 

 Caledonia. Andaman Is. (Brit. Mus.).
