408 MR. E. A. SMITH ON SHELLS FROM ADEN. [JunC 16, 



Hiods, with which species he unites a considerable number of what, 

 to my mind, are quite distinct species. 



51. Nassa albescens, Dunker (var. fenestrata, Marrat). 

 Hab. Red Sea, India, Ceylon, Seychelles, Singapore (Brit. Mus.) ; 



Mozambique, Philippines, Moreton Bay, Australia (Marrat). 



The above are the localities for the Ya.rietj fenestrata. I am not 

 sure that the shell figured by Reeve (Con. Icon. f. 100) is the same 

 species as that described by Dunker under the uaiue albescens. The 

 latter is stated to be West-Indian, and although Reeve also quotes 

 West Indies, the specimen he figures was probably Australian, as it 

 agrees precisely with specimens in the Museum from that region. 



52. Nassa coronata (Linn.). 



Hab. Natal, E. Africa, Seychelles, Andaman Islands, Darnley 

 Island (^Brit. Mus.). Other localities are Madagascar, Java, 

 Philippines, &c. 



53. Nassa gemmulata, Lamarck, var. 



Sab. Red Sea, Muscat, Japan, Philippines, Cape York, New 

 Guinea, Queensland. Aden (Caramagna). 



The shells from Aden belong to the variety described by A. 

 Adams under the name of N. verrucosa. They are considerably 

 larger than Adams's type as figured by Reeve (Conch. Icon. f. 36). 



54. Nassa fissilabris, A. Adams. 

 Hah. Philippines. 



This species is peculiar on account of the unusually distinct sinus 

 at the upper end of the labrum and for the development of the 

 callosity above it. It is perfectly distinct from N. nodicostata 

 and crenolirata of A. Adams and albipunctata, Reeve, which are all 

 united by Try on \ but which I consider separate well-defined species. 



55. Phos roseatus. Hinds. 

 Hah. Philippines. 



Only a single specimen was found by Major Yerbury. 



56. Rapana bulbosa, Solander. 



Hab, China, Japan, Philippines. Red Sea, Kurachee, Singapore 

 (Brit. Mus.). 



57. Purpura rudolphi, Lamarck. 

 Hab. Philippines, Natal. 



58. Purpura hippocastanum, Lamarck. 



Hab. Red Sea, Seychelles, Amirantes, Mergui, Japan, Philip- 

 pines, N.E. Australia, Fiji, and New Zealand {Brit. Mus.). 



Many other localities have been quoted for this species. The 

 synonymy given by Tryon (Man. Conch, vol. ii. p. 162) is so 

 ridiculous that it is beneath criticism.
