NEW SPECIES OF MARINE SHELLS, 244, 
Eastern Islands, and a few other species have been described, but are 
hardly known. 
TELLINA KOLABANA, sp. nov. (Pl. 1, f. 28). 
T. testd ovata, albescente, solidiusculd, convexd, latere postico valde 
bicarinato, antico oblongo, transversim concentrice liratd, apud umbones 
Sere lav, flavo tinctd, postice aspera, usque ad marginem ventralem. 
Lat. 27 mill. 
one. hae. 
Hab. Bombay (Abererombie). 
A somewhat thickened shell, as 7. balthica (L.) ; white, yellow, or 
orange-tinted at the umboes, convex, distinctly posteriorly bicarinated, 
the concentric lire becoming very rough and distinct at the posterior 
angle. 
Rare ; only one or two specimens. 
TELLINA (MRA) LECHRIOGRAMMA, sp, nov. (Pl. 1, f. 22). 
T. testa albidd solidrusculd, donaciforme, postice abbreviatd, subobliqua, 
anticé elongata, undique concentricé tenui-lirata, nitida. 
Long. 14 mill. 
Neate vor Genres 
Hab. Bombay (Abercrombie). 
Apparently not uncommon, but mostly in imperfect condition, half 
valves only. It is like 7. pygmea (Phil.) in shape, but of thicker 
consistency, pure shining white, very finely concentrically lirate, 
posteriorly abbreviate, anteriorly elongate, with some of the appearance 
of a Mesodesma or Donacilla. 
THRACIA SALSETTENSIS, sp. nov. (PI, 1, f. 24). 
T. testa pertenuz, oblonga, alba, postice flexuoso-quadrata et subrostrata, 
antice ovato-oblongd, valvd sinistrd subplanatd, dextrd convexa, valvis 
ambabus, presertim sinistra, plicis concentmicis undanter suceinctis posticé 
fere applanatés, 
Long. 36 mill. 
Piatti S20 es 
Hab. Bombay (Abercrombie). 
A remarkably delicate semi-trapezoid species, of which numerous 
single valves were found, but no quite perfect specimen. The left 
valve is almost flattened, with a broad longitudinal depression, inclining, 
posteriorly, almost down the centre of the left valve from the umbo,
