298 SPECIES OF THE SYSTEMA. 
SUurvex melongena. 
The Pyrula melongena (Kiener, Coq. Viv. Pyrula, f. 1) of 
authors is marked for this shell in the Linnean cabinet. From 
the accuracy of the synonymy the species was readily identified 
by naturalists. Plate 904 of Lister’s ‘Historie’ was correctly 
referred to in the revised copy, where, too, “ Rore glauco ob- 
ducta” and ‘“ Jamaica” (the last copied from Lister) have been 
added. 
Murex cartosus. 
The conclusion of Deshayes, that this species would find its 
representative in the Melanopsis costellatus of Férussac (Mem. 
Soc. H. N. Paris, vol. i. p. 157) is confirmed by an examination 
of the Linnean collection. The only specimens in the cabinet 
which precisely answer to the definition are some young 
examples (pl. 2, f. 6) of the many-ribbed variety (with from 
14 to 17 coste on the body), a form which I believe to be 
specifically identical with the more remotely ribbed Buccinum 
Maroccanum of Chemnitz (pl. 210, f. 2082, 2083), which I have 
received along with it from Seville. The elevation of the spire 
varies so greatly in the species, that Rossmiissler’s drawing 
could not be cited as an exact portraiture ; the belt of nodules, 
too, which, in some individuals, forms a connected spiral band 
adjoining to, though clearly separated from, the suture, in 
others is obsolete or scarcely distinguishable. The following 
manuscript note, in our author’s own copy of the ‘Systema,’ 
“An potius Buccinwn, affine B. preroso, sed majus et pli- 
catum,” reveals that he doubted the appropriateness of the 
generic position he had assigned it: the comparison with 
prerosum throws light upon its affinities.
