SOLEN. 29 
SOLEN. 
Solen bagina. 
Of the four synonyms of this shell, three (Rumphius, Argen- 
ville, Klein) refer to an Indian, one only (Gualtier) to an 
European shell; yet authors have seemed obstinately bent 
upon reserving the name for the latter, in despite of the lan- 
guage of the ‘ Museum Ulrice,’ ‘“ Extremitas postica crassior, 
oblique extrorsum truncata, antice vero rotundata.” This pas- 
sage, so inapplicable to the Solen vagina of British writers, 
which indeed is not present in the Linnean collection, perfectly 
accords with the characters of Solen brevis, of which an exam- 
ple (Mawe, Conchol., pl. 5, f. 2) is preserved in the cabinet, and 
alone of the shells there present suits both the description and 
synonymy. Hence there can be no reasonable doubt that it 
was the type of the species. 
Solew stliqua. 
The Solen siliqua of authors (Wood, Gen. Conch. pl. 26, 
f. 1) is marked for this species in the Linnean cabinet: the 
manuscript adds “ List. t. 409” to the former synonymy. 
Of the published synonyms, the figures in Ginanni and Ar- 
genville are very bad; of Lister, admirable ; of Gualtier, 
Bonanni, and Plancus recognisable. 
Solew ensts. 
The Solen ensis of authors (Wood, Gen. Conch. pl. 28, f. 1, 2) 
is still preserved in the Linnean collection, and alone of the spe- 
cies there present agrees with both description and figures. The 
reference to Lister’s work on English shells greatly facilitated 
its former identification; the delineation, though not good,
