lip more effuse and angular, and not so incrassate ; colour a pale 

 unicolorous isabelline yellow, which no doubt suggested to Lamarck 

 the trivial name. 



Strombus (Conomurex) luhuanus L. — Three, quite typical. 

 Australia, New Guinea, Philippines, Loyalty and Fiji Islands. 



Pterocera (Harpago) chiragra L. — Only in young state. 

 Indian Ocean, Philippines, Loyalty Islands, Polynesia. 



Rostellaria curvirostris Lm. — Several, mostly in a young state. 

 Red Sea, Moluccas. 



Family CERHHllDsE. 



Cerithium carnaticum M. & S., vide antea, p. 31. 



Cerithium cf. corallinum Defr. — Three examples, which we con- 

 sider very near to, if not identical with, this species. 



Cerithium litteratum Born. — Several specimens. West Indies, 

 Florida. 



Cerithium morus Lm. — A well-known, variable, and widely- 

 distributed species. Madagascar, Red Sea, Philippines, Australia, 

 Loyalty and Fiji Islands. 



Cerithium nodulosum Brug. — One fine specimen. Singapore, 

 Moluccas, Philippines, Lifu (Hadfield). 



Cerithium vulgatum Brug. — Some typical examples. There are 

 few shells with such an enormous synonymy of varietal names as 

 this species, although it does not vary more than is usual in the 

 genus. Tryon figures a number of these so-called varieties, but does 

 not recognise their claim to separation from the type. Southern 

 Europe, West Africa, Cape of Good Hope. 



Cerithium yerburyi E. Sm.— Allied to C. morus L. but more 

 attenuate. Originally described from Aden, but no doubt it will be 

 found all along the Indian Coasts. 



Colina macrostoma Hinds. — A very interesting form, of which 

 only one occurred in Prof. Henderson's dredgings. Straits of 

 Malacca, Borneo. 



Colina selecta M. & S., vide antea, p. 31. 



Pyrazus palustris L. — Two, of typical form. India, Java, 

 Australia, Loyalty Islands. 



Family PLANAXIDyE. 



Planaxis nigra Quoy. — Six, of a plain-coloured, smooth, unpolished 

 shell. New Ireland, Fiji and Sandwich Islands, South Africa. 



Planaxis sulcatus L.* — Eighteen, all well grown and 

 unusually large. Indian Ocean, Sandwich Islands, Australia, Philip- 

 pines, Mauritius, South Africa.
