affects the question of nomenclature under Engina. There has been 

 more confusion as to the synonymy and arrangement of this very 

 beautiful and distinct mollusc than one could have supposed possible. 

 Eeeve in 1846 described a Buccinum pulvhrum (Conch. Icon., fig. 80) 

 from the Gallapagos Isles. This has been, unwarrantably, mistaken 

 for a western representative of this eastern species, and in consequence 

 the erroneous idea arose, of a shell possessing a cosmopolitan range 

 in the Tropics of both hemispheres. The Buccinum pulchriim, Eeeve, 

 which is perhaps a Sistrum, or, more probably, an Eyigina, is of quite 

 special configuration, and perfectly distinct from 1!. elegcms, Dkr. 

 The Cumin gian type of the latter species came from Capul Island, 

 Philippines. From the Andamans we have only seen the white- 

 mouthed variety, in which the body of the shell is of a pale straw 

 colour. 



12. SiSTEUM EiciNirs, L. (= Ricinula arachnoidea, Lam.). This 

 species, represented in the collection by fine typical specimens, is 

 extensively distributed throughout the East Indies. 



13. Oliva emicator, Meusch. Better known by the later name of 

 0. guttata, Lam. A variable species, very widely diffused throughout 

 the East. 



14. Latirus CPertsternia) jfASSATULUS, Lam. Brilliantly coloured 

 and quite typical. Eanges northward to the Philippines, and south- 

 ward to Ceylon. 



15. MiTRA ETJBiGiNOSA, Eccve. One example. Recorded from 

 Ticao Island.
