3 Tahiti ; ex Mus. Godeffroy. 



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



Unfoi'tunately tliesc last are not quite adult ; apparently tbe 

 sculpture of this species at the Andamans is most vaidable. 

 Some have the characteristic, longitudinal, undulating furrows 

 of L. granocostata.

 12 Hongkong J coll. R. Hungerford, Esq. 



Lone. 10, diam. 8 mil. Very van' able as regards sculpture, 

 sometimes only spirally striate, occasionally more or less dis- 

 tinctly granuiose ; it can always be easily distinguished from 

 L, ventricosa, which lives with it, by being always an gulate 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. 

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

 fio-. 13 of L. nodosa fairly represents some of the Hongkong 

 specimens. 



var. fljiensis. 



Littorina fijiensis, Heeve, Icon. 1857 ; emend. Blaitens in Donum Bism. 

 as L. viiiensis. 

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



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

 ceding. It can scarcely be the L. vitoisis of Dunker, Malac. 

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