32 SPECIES OF THE SYSTEMA. 
figures, were virtually rejected by their omission. Schumacher, 
a very careful and independent observer of the species described 
by Linneus, remarks (p. 159) that it was not likely that our 
author would have placed a clearly hinged Cardiwm in the 
genus Solen. 
Solew mitruiuitws. 
Linneus, in his own copy of the ‘ Systema,’ has wisely ex- 
punged this Saxicava from the list of species, with the remark 
“Tdem cum Mya Arctica,” which latter he proposed to transfer 
to this genus. 
Solew bivrews. 
One shell alone (pl. 1, f. 1) in the entire Linnean collection 
precisely corresponds to the published description of this spe-- 
cies, and, as our author has expressly declared his possession 
of an example, no reasonable doubt can be entertained of the 
typical authority of the specimen. It is the Glawconome virens 
of Reeve (Conch. Icon. Glauce. f. 9), whose attention I directed 
to my identification. 
TELLINA. 
Many of the Tellens in the Linnean cabinet have been ejected 
from their original boxes, and placed in pasteboard trays, on 
which the names are written. Although the types have been 
so carefully distinguished that where no cyphers were found 
“ ex descriptione ” has been added; the writing, not being the 
original one, diminishes the authority of the specimens.
