2 Mauritius; coll. G. Nevill, Esq. [7f, 5], 



3 Tahiti ; ex Mus. Godeffroy. 



10 Andamans; coll. J. Wood-Mason, Esq. 



Unfortunately these last are not quite adult ; apparently the 

 sculpture of this species at the Andamans is most variable. 

 Some have the characteristic, longitudinal, undulating furrows 

 of L. granocostata. 



54. Littorina miliaris. 



Littorina niiliaris, Quoy, 1832, pi. 33, figs. 16-19, " He de I' Ascension"

2 Madagascar ; coll. J. Caldwell, Esq. 



3 Nagasaki ; coll. R. Hnngerford, Esq. 

 12 Hongkong; coll. R. Hungerford, Esq. 



Long. 10, diam. 8 mil. Very variable as regards sculpture, 

 sometimes only spirally striate, occasionally more or less dis- 

 tinctly granulose ; it can always be easily distinguished from 

 L. ventricosa, which lives with it, by being always angulate at the 

 base of the aperture, instead of rounded. It is a larger, coarser 

 variety than the Ceylon form, and may be specifically distinct ; 

 it can be easily distinguished by the more regular spiral sculp- 

 ture and its sombre coloration, wanting the characteristic 

 black and white " filleted " bands [as seen also in Philippi's fig. 

 of L. leucosticta] ; it is as much like Philippi's figure of L. 

 subnodosa as that he gives of L. nodosa, Gray. Reeve's 

 fig. 13 of L. nodosa fairly represents some of the Hongkong 

 specimens. 



var. fljiensis. 



Littorina fijiensis, Seeve, Icon. 1857; emend. Martens in Donwm, Sism. 

 as L. vitiensis. 

 2 Tahiti; coll. H. Pease, Esq. [sent as " L. fijieusis "]. 



Undoubtedly, I think, not specifically separable from the pre- 

 cedino-. It can scarcely be the L. vitewsts of Dunker, Malac u 

 Blat. 1871, Fiji Isl., long. 10, diam. 7 mil. ?
