[Auckland], they are utterly without value in my eyes ; the 

 latter's specimens probably came from Madras ? The above 

 recorded specimens are a constantly much smoother form than 

 L. ventricosa, with even less marked coloration and distinctly 

 more produced spire in all cases, though this last is a variable 

 character in both species. E. A. Smith describes a closely 

 allied, but more compressed form, from the Solomon Islands, 

 as L. melanacme, P. Linn. Soc. XII, 1876, pi. XXX, fig. 21 ; 

 this may be the L. novce-z eland ice of Fischer from New Cale- 

 donia ? 



52. Littorina reticulata. 



Littorina reticulata, Anton, Verz, Conch., p. 53, Sah. ? and Philippi, Ahh, 

 pi. IV, fig. 12; ?=L. granocostata, Reeve, 1857, fig. 79, Brisbane; 

 Mascarene Islands, fide Martens. 



7 Praslin Islands, Seychelles ; coll. G. Nevill, Esq. 



I took this distinct little species alive at one spot on Praslin, 

 and never saw it elsewhere from these seas, unless the Andaman 

 specimens, quoted below, should prove to belong to it. My 

 specimens agree exactly with Reeve's figure and description. 



Long. 7, diam. 6 mil. 



53. Littorina millegrana. 



Littorina millegrana, PMlippi, Abb. Ill, 1850, pi. VII, fig. 15, Red Sea ; 

 Suez, fide McAndrew. 



5 Mesbek [Persian Gulf] ; coll. W. T. Blanford, Esq. 



Not in a satisfactory condition,

var. einerea. 



Littorina einerea, Pease, Amer. Journ. Conch. IV, 1870, pi. VIII, fig. 14, 

 Marquesas ; alt, 7, diam. 51 mil. 



10 Balapiti, Ceylon; coll. G. Nevill, Esq. 



These agree exactly with Pease's above-quoted figure, the 

 spire is relatively higher than in Philippi's figure; the 

 species is a connecting link with the Sub-Genus Tectarius ; 

 H. and A. Adams indeed considered it a species of that Genus.'
