PSEUDOLIVA, Swainson. 
Gen. Char. Shell thick, ventricose ; spire short ; 
aperture large, longitudinal, oval, with a broad, 
short canal at the base and a narrow canal at the 
opposite extremity ; outer lip with a tooth on its 
sharp edge corresponding to a groove around 
the outside of the lower part of the whorl ; 
inner lip thick, tumid at the upper part. 
A genus of shells nearly related to Oliva and Eburna , 
and of which the typical recent species is the Buccinum 
plumbeum of Chemnitz. Its most obvious character is 
the furrow upon the lower part of the whorl, termina- 
ting with a tooth on the edge of the lip, as in Ancillaria ; 
a genus to which some of the fossil species approach, in 
having the inner lip spread over a part of the spire. 
PSEUDOLIVA obtusa. 
TAB. DCXXII. 
Spec. Char. Obovate, smooth, with a few striae 
below the furrow ; spire short, small, partly 
concealed by the expansion of the inner lip ;
