1891.] MR. K. A. SMITH ON SHELLS FROM ADEN. 405 



34. MUREX HAUSTELLUM, Lillll. 



Hah. Red Sea, Ceylon, Mauritius, China, Philippines. Aden 

 {Caramagnu^. 



35. MuREX (Chicoreus) angtjliferus, Lamarck. 



Hah. Aden (Jousseaume), Red Sea, Persian Gulf, Indian Ocean, 

 Sej'chelles, Bourbon, Ceylon. 



In Cnmin2;'s collection is a shell, named M. lycacantha, Jonas 

 (not cyacantha as given bv Sowerby and copied by Tryon), which 

 appears to be only a manuscript name. It evidently is the same as 

 M, angiiliferus. 



36. MuREX (Chicoreus) ramosus, Linn. 

 Hub. Red Sea, Indian Ocean, Polynesia, &c. 



37. Melongena paradisiaca (martini), Reeve. 

 Hah. Red Sea, Mozambique, Natal, Ceylon, Bourbon. 



The epidermis of this species is quite velvety to the touch and is 

 covered with innumerable veiy short glossy hairs, disposed in longi- 

 tudinal series upon the lines of growth ; they are invisible to the 

 naked eye. The operculum is unguiculate, more than twice as long 

 as broad, strong, thickened underneath along the outer margin, and 

 has the nucleus terminal. 



38. PiSANiA TRiTONOiDES (Reeve). 



Bucdnum tritonoides, Reeve, Conch. Icon. vol. iii. pi. x. f. 77. 



Hah. Philippine Islands. 



I cannot agree with Tryon in considering this species a variety of 

 P. ignea, Gmelin. The differences of form, colour, and sculpture 

 are, I think, sufficient to separate them. 



39. Tritonidea undosa (Linne), var. 



Hah. Malacca, Australia, Philippines, Viti, Paumotus, Society 

 Islands. 



This species varies considerably in size. The specimens from 

 Aden are very small in comparison with the shell figured by Reeve ^ 

 from the PhiHppines, being only 22 millimetres in length. They 

 diflfer also in the absence of the yellow margin to the aperture. 



40. Columbella propinqua. (Plate XXXIII. fig. 3.) 

 Testa acuminata, ovata, solida, olivacea, interdmn aurantia, guttis 



et maculis alhis fusco marginatis variegata ; anfractus 8, con~ 

 vexiusculi, Iceves vel obsolete spiraliter striati, ultimus bushn 

 versus distinctius transversim striatus ; spira hrevis, leviter 

 concave acuminata ; apertura albida vel pallide ccerulea, 

 angusta, longitudinis totius | adcequans ; labrum extus paulo 

 incrassatum, intus denticulatum, denticulis mediants paucis 

 cceteris majoribus ; columella callo ienui induta. 



Longit. 16g millim., diam. 9. 



This species is very like C. vulpecula, Sowerby, but differs in 

 ' Con. Icon. vol. iii. Buccinum, jjl. viii. fig. 65.
