 fig. 17-18. 



PI. XX, fig. 74, 75, var. A, 76, var. B. 



B. testA parva, ovato-conica, nitida, pellucida, acuta, luteo-albida, longi- 

 trorstim tenuiter plicata, transvers& striata ; anfractibus convexiusculis, 

 margine superior! albis, fusco-castaneis, aut fusco-coerulescentibus ; aper- 

 tura alba ; labro dextro crasso, intus striato. 



Shell small, ovate, conical, rather shining, pointed ; spire 

 formed of six or seven indistinct whirls, often ornamented with 

 longitudinal folds, which are rarely continued to the base of 

 the lowest whirl, and which are crossed by very fine and 

 slightly marked transverse striae. Aperture white ; right lip 

 thick, white externally, and denticulated within. Columella 

 smooth, with two guttules at the base. The coloring of the 

 shell is very various. The ground is generally of a yellowish 

 white ; the transverse striae are accompanied with very fine 

 lines, white and of a red bay color ; reddish, or bluish brown 

 spots, intersected with white, form zones upon the upper-part 

 of each whirl. At the base, and the middle of the lowest, the 

 brown lines are more marked. 



Length 6 lines. Width 3 lines. 



Inhabits the Mediterranean, the coasts of Southern France, 

 and of Corsica, where it is very common.

 authors, deceived by the different shades of the shell, have di-

 Coquilles de la Corse, pi. 8, fig. 15, 16, has established a species 

 under the name of BUCCINUM Ferussad, the greater part of the 

 characters of which belong equally to that which he had already 

 called BUCCINUM Cuvieri, the same we have just described. In 

 the Ferrusaci of that author, the longitudinal folds, which are 

 prolonged upon the lowest whirl, are more prominent, the color
