413 MELVILL AND STANDEN : SHELLS FROM LIFU. 



Odostomia bulimoides Souverbie. — Agreeing with the 

 description and figure in everything excepting size, our 

 two examples being only 3 mm. in length. 



O. versicolor M. & S., p. 379, 1897. 



Pyrgulina gliriella M. & S., p. 303, 1896. 



Turbonilla belonis M. & S., p. 303, 1896. 



Family NERITIDAL. 



Nerita pica Gould. — A small grey and white mottled shell. 

 Native of Polynesia, and extending as tar north as Japan 

 (N. japonica Dunker). 



Neritina Souverbiana Montrouzier. — Six specimens. A 

 pretty pale fulvous species nearly allied to N. Rangiana 

 Recluz and N. viridissima T. C. 



N. (Vitta) viridissima Tapp. C— Five specimens, all beauti- 

 fully fresh, and with characteristic black pencilled mark- 

 ings. The N. viridis L., with which this has been 

 confounded, is unmarked, and a native of the Antilles. 

 Tryon associates it with N. Rangiana Recluz. 



Family TURBINID.E. 

 Turbo (Senectus) nivosus Reeve. — A small example. 

 T. (Senectus) setosus Gmelin. — Worn, but evidently this 



species. 

 Alcyna lifuensis M. & S., p. 312, 1896. 



Family TROCHIDAi. 



Gibbula fasciata Born = Monilea carneola Lamk. — Also 

 a native of the West Indies, where one of the authors has 

 collected it. It is strange to find it in Lifu, but we can see 

 no appreciable difference in the appearance of individuals 

 from these shores. 



Oxystele suavis Phil. — Endemic in the New Caledonian 

 group of islands. One example only. 



Pyramidea histrio Reeve. — Six prettily coloured examples, 

 all small.
