TELLINA. 39 
Tellina traquibalbts. 
As our author has stated his possession of this species, and 
one shell alone (pl. 1, f. 6) in the entire collection agrees with 
the description, no reasonable doubt can be entertained of the 
typical authority of that specimen which I consider to be a 
produced form of the Pandora rostrata of Lamarck. The spe- 
cies queried by Gronovius for this shell is the Anomia tabacea 
of his plates, an aged Pandora, the young of which subsequently 
received the name of trilineata from that Montagu of America, 
the illustrious Say. 
Gelltwa trtifasetata. 
By a similar mode of analytical examination one is enabled 
to identify this pretty species (pl. 1, f. 5), which I take for the 
Donax vittata of Lamarck as delineated in Delessert’s folio 
(Ree. Coq. pl. 6, f. 12). The tray which contains it is also thus 
named in the collection (the inscription was probably copied 
from that in the original tin box when the specimen was re- 
moved), but the writing itself is modern, and hence of little 
authority. The same reference to Lister is appended to both 
this (not so in the tenth edition) and the next species, and with 
equal incorrectness, for Psam. Ferroensis, the shell represented 
by him, does not agree with either. On reference to the 
‘Fauna Suecica’ we shall find a mere repetition of the original 
diagnosis in the tenth edition. The stated locality is erro- 
neous. 
Gellina twearwnata. 
The Tellina squalida of Montagu (T’. depressa, Wood, Gen. 
Conch. pl. 45, f. 3) is marked in the collection for this shell, 
and well agrees with the description of it. The cited figure of 
Gualtier is very rude, yet not so unlike the species. The 7’.
