LITTORINIDE. 153 
[Auckland], they are utterly without value in my eyes; the 
Jatter’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, pl. XXX, fig. 21; 
this may be the L. novee~zelandie of Fischer from New Cale- 
donia !

pl. 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. 5 mil.

Littorina millegrana, Philippi, Abd. IIT, 1850, pl. VII, fig. 15, Red Sea;

Not in a satisfactory condition.

Littorina cinerea, Pease, Amer. Journ. Conch. IV, 1870, pl. VILL, Jig. 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.
