270 SPECIES OF THE SYSTEMA. 
Stronmbus marginatus. 
This shell is not mentioned by Linneus as forming part of 
his collection. The very peculiar feature “dorso marginato,” 
which, in conjunction with the few other specified charac- 
teristics, is scarcely to be found in any other Strombus, induced 
Schréter to fix upon a shell (Sow. Thes. Conch. vol. i. Strom. 
f. 17) that so excellently agrees with the brief description that 
his selection has met with universal assent. 
Stronbus Huhuawus. 
The Strombus Luhuanus of authors is marked (Sowerby, 
Thes. Conch. vol. i. pl. 7, f. 54) for this species in the Linnean 
collection; and two representations of it “‘ Pet. Gaz. 98, f. 10,” 
“ List. 851” have been correctly added to the synonymy in the 
revised copy of the ‘Systema.’ Argenville’s drawing repre- 
sents S. gibberulus; the reference to his work must conse- 
quently be suppressed: the other figures referred to were 
designed for Luhuanus. 
Strombus gibberulus. 
The Strombus gibberulus of authors is marked (Sowerby, 
Thes. Conch. vol. i. pl. 6, f. 19) for this species in the Linnean 
cabinet, and “ Faux atropurpurea” added in the revised copy 
of the ‘Systema.’ Naturalists easily identified this abundant 
shell from the peculiar distorted look that characterises it, and 
from its generally accepted synonymy. The whorls of the 
spire in unpolished examples are not smooth, as stated in the 
‘Museum Ulrice,’ but are spirally striated.
