LIOPLAX. 35 
times almost channelled, aperture small, 
broadly ovate, umbilicus partly or entirely 
closed. Light olive color, blue within. 
Length 20, diam. 8 mill. 
Georgia and Alabama. 
I agree with Mr. Binney in considering Mr. 
Lea’s P. Elliottit to be identical with this spe- 
cies. The carina is obsolete or nearly so on 
the lower whorls, but is more or less distinct 
on those of the spire. 
3. LIOPLAX SPILLMANII, Lea. 
Plate 14, fig. 7. Plate 15, fig. 8. 
Shell subelliptical, rather thin, imperforate, 
whorls 5, biangulated around the middle, the 
angles carinate, sutures well impressed ; aper- 
ture small, narrowly ovate, surface closely 
covered with revolving striew. Light- green, 
bluish within. 
Length 33, diam. 13 mill. 
Jackson County, Mississippi. 
Very distinct from having a plane surface 
girdling each whorl, caused by the double 
carina.
