86 GENUS BUCCINUM. 



pears in each of these varieties. Blainville (Faune Frangaise, 

 p. 182), considers the BUCCINUM inflatum of Lamarck as a sex- 

 , ual variety of the BUCCINUM mutabile. We agree in opinion 

 with this naturalist; there is no difference between the two 



'-shells.

B. test4 ovata, ventricosa,lseviuscula, rufa; anfractibus convexis, ultimo 

 superne basique striato; spira brevi, apice obtusiuscula ; labro simplici, 

 inferne repando. 



Shell ovate, ventricose, almost smooth, of an uniform red 

 color ; spire formed of six or seven convex whirls, covered 

 upon their whole surface with very fine transverse striae, which 

 are not apparent upon the middle of the lowest whirl ; spire 

 rather short, slightly obtuse at its summit ; aperture whitish ; 

 right lip thin, smooth ; left lip extends upon the body of the 

 last whirl ; columella smooth and arcuated. The tint of this 

 shell inclines a little to a brick-color. 



Length 1 inch. Width 8 lines. 

 Inhabits the Mediterranean ? 



This shell appears to me the same as the BUCCINUM mutabile ; 

 but as we find it in collections only in a sub-fossil state, it is to 

 be supposed that its colors have disappeared ; this sole difference 

 excepted, we find the same characters, and above all the trans- 

 verse striae upon many of the specimens of this last BUCCINUM ; 

 upon others, also, there are no spots, and the reddish color 

 appears only more pale. 



The Buccinum which I have just described, has been called 

 ventricosum by Lamarck. Having already a species of this 

 name among the BUCCINA, I have thought it improper to retain 

 it for this species.
