C O N U S fumig-atus. 



&' 



Family Strombidae. Sub-family Conianae. 

 Generic Character See Lamarck. 



Specific Character. 



Shell smooth, spire very short, channeled, or with the ivhorh 

 concave : colour chcsmit, belted icith tchitc, and articulated 

 rows of chesnut dots.

A species not conspicuous for its beauty, but by no 

 means of common occurrence : its close resemblance to the 

 next has induced us to illustrate both by figures. C. 

 fumigatus seldom exceeds the size here represented ; it 

 may at once be known iroxn franc'iscanus (which is a much 

 smaller shell,) by the spiral whorls being concave^ instead 

 of convex : this species occurs in the Indian Ocean. 



If the student compares either Strombus Luhuanus, 

 Mauritiamts, or Persicus, with any of the wide mouthed 

 Cones, he will immediately perceive the affinity between 

 the two groups. In both, the operculum of the animal is 

 small, but in Conus it seems reduced to a mere vestage ; 

 while the shell, nearly rolled upon its own axis, indicates 

 the near approach which Nature has now made towards the 

 Cowries ; a family, however, essentially distinguished by 

 the great developement of the mantle, and the total 

 absence of an operculum. 



CONUS franciscanus. 



Shell smooth, chesnut, icith two ivhite bands, the upper one near 



the suture: spire short, the ivhorls convex. 

 C franciscanus. Lam. Si/st. 7. 493. Ency. Meth. 221 .f. 5. 



Lamarck mentions Africa and the shores of the Mediter- 

 ranean, as the native locality of this shell. It escaped our 

 researches on the coasts of Italy, Sicily, and Greece, and 

 we suspect it to be an Oriental species.
