400 MR. E. A. SMITH ON SHELLS FROM ADEN. [June 16, 



6. CoNUs BETULiNtfs, Linn. 



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

 Aden {Garamagna). 



I do not agree with Try on' in considering C. suratensis a variety 

 of this species. 



7. CoNus STRIATUS, Linn. 



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

 Australia, New Caledonia, Viti Islands. Amirantes, Solomon 

 Islands, Island of Annaa {Brit. Mus.). 



8. CoNus GENERALis, var. 



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



0. maldivus, Hwass, C. monile, Hwass, and G. bayani, Jousseaume, 

 should, I think, be considered varieties of this species, and C. 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 ACXJMiNATUs, Hwass. 



Hah. Red Sea. 



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

 The latter is placed by Tryon among the synonyms of G. 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. 



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

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

 {Garamagna). 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, Rccve. 



Hab. Red Sea. 



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

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

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

 the six specimens from Aden possesses these characteristics. 



13. CoNus LiNEATUs, Chemuitz. 



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

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