Tellina. This genus is treated of by Sowerby in the late Mr. Reeve’s Con- 
chologia Iconica, parts 268 & 269, 262-266. N ew species are : — T. substrigosay 
meloy Malaga; inflatay caseusy arcuatay occidentalis (Morch), West Indies; tu- 
midia, Jamaica; macandreiy Madeira; longirostratay malaccana, Malacca; 
corbisy tenuistriata, graciliSy Australia ; excavatay in<xquivalvis, Australia. 
Tellina baltica (L.). The Mediterranean specimens are of small size, and 
resemble the fossil specimen figured in S. Wood’s ^ Crag Mollusca.’ T.planata 
(L.) is obtained rarely alive by means of the dredge, because it lives in very 
shallow water, where the dredge cannot be used. T. incarnata (L.)=<?e- 
pressa {0(vaQ\.) = squalida (Pult.) ; a pale variety is T. daniliana (Brusina). 
T. my wa (Poli) = <cnm5 (Donovan). T. (Qronov.), the Mediterra- 
nean specimens are narrower in shape than those from the North Sea, 
. T. distorta (Poli) is a distinct species. T. donacina (L,), one of its varieties 
is Payraudeau’s T. lantivyiy whilst T. oudardi (Payr.) = distorta of Hanley, not
