86 GENUS BUCCINUM. 
pears in each of these varieties. Blainville (Faune Francaise, 
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. ,

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 strie, 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 ip extends upon the body of the 
last whirl; columella smooth and arcuated. ‘The tint of this 
shell inclines a little to a brick-color.

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 strie 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 
veniricosum by Lamarck. Having already a species of this 
name among the Buccina, I have thought it improper to retain 
it for this species.
