MUREX. 291 
Murex sevodiciulator. 
The Triton scrobiculator (Chemnitz, Conch. Cab. vol. x. 
pl. 163, f. 1556, 1557) of authors is marked for this shell in 
the Linnean collection. The species was pictorially defined in 
the tenth edition of the ‘ Systema,’ by the single reference to 
Gualtier’s engraving being in harmony with the brief descrip- 
tion. Of the other synonyms, only appended in the twelfth 
edition, Adanson’s is correctly cited (at least, it has been 
generally so quoted); Lister's was probably a misprint for 943, 
f. 39 (not 34, 39), which figure also has been attributed to scro- 
biculator ; Seba’s and Petiver’s had been already referred by 
Linneus to Murex rana, and are decidedly Ranelle. The 
reference to the ‘Gazophylacium,’ indeed, has been erased in 
the revised copy of the ‘ Systema.’ 
SUurex reticularis. 
No aid is afforded us by the Linnean cabinet towards the 
elucidation of this species, a brief description of which, accom- 
panied by two apparently antagonistic synonyms, made its ap- 
pearance in the tenth edition of the ‘Systema.’ Of these the 
cited figure of Gualtier represents the Ranella tuberculata of 
Broderip, that of Bonanni the R. gigantea of Lamarck. Both 
these shells harmonise fairly enough with the succinct diagnosis, 
but the “columella subedentula” is far more suited to the 
former. The latter, however, has been erroneously taken by 
Gmelin, Dillwyn, and certain other writers, for the true repre- 
sentative of reticularis, solely on account of Bonanni’s very in- 
accurate figure of it. But since that Ranella has already been 
described in the ‘Systema’ as Murex olearwum, little doubt can 
exist that Linneus regarded this figure of Bonanni as either a 
magnified delineation or a larger form of the shell figured by 
Gualtier, which, except in size, it more nearly resembles than 
it does the Mediterranean shell we know it to be intended for ; 
the longitudinal plice extend in the engraving over the entire 
body, the varices are drawn as uninterrupted, and the upper
