264 SPECIES OF THE SYSTEMA. 
most, then, it can only be regarded as an approximation to the 
general aspect. Linneus had proposed to remove the species 
to the genus Strombus; so that, coupling this circumstance 
with the recorded peculiarities, it is probable that it belonged 
to Cerithium, and to the short-tailed section (Potamis), or it 
would have been placed by him in Murex (as he designed with 
St. tubercularis) along with the other true Cerithia. Now of all 
the specimens in the Linnean collection (where the presence 
of murinwm is declared in the original list that accompanied 
the tenth edition), the Cer. granulatum (as in Kiener) alone 
bears any likeness to the declared characteristics, without 
being utterly unlike the engraving of Gualtier; the example 
(Born, Test. pl. 11, f. 16), however, being decorticated, does 
not answer to the colouring, and the presence of the species 
is not recorded in the final list, so that, although the identity 
of the two is not so improbable, it cannot be absolutely 
demonstrated. 
STROMBUS. 
The following addition to his generic characters was pro- 
posed by Linneus for his revised edition of the ‘Systema:’ 
“Labium postice ad latus sinu excavata exceptis 502, 510, 
514.” 
Stronmbus: fusus. 
When this species was first constituted, our author, as we 
learn from the catalogue of his collection, did not himself 
possess a specimen of it. It was pictorially defined in the 
tenth edition of the ‘Systema,’ by no less than three references
