Shell oval, compressed and expanding outwards, of delicate but 
not fragile texture, semitransparent and glossy ; sculpture, numerous 
and close-set spiral rows of minute links, arranged in a chain-like 
fashion, which vary in shape from roundish-oval to oblong, besides 
occasional intermediate lines as in P. scabra; the edge of the mouth 
(especially at its base and on the upper part of the outer lip) is 
finely scalloped by the continuation of the spiral sculpture ; color 
as in the last species ; spire extremely small, but prominent ; whorls 
2-3, similar (except in size) to those in the last species ; suture nar- 
row, deep and channelled; mouth equalling about three-fourths of 
the circumference of the shell, broadly oval, contracted above by 
the periphery, with a bluntly rounded (or almost truncated) base ; 
outer lip flexuous, slightly indented or concave in the middle; the 
top is level with the spire, the shell being placed mouth downwards ; 
inner corner cloyen and producing the same partial disconnection 
of the body-whorl as in the last species ; inner lip forming a broad 
and thickened glaze. (Jeffr.).
