Mr. Gray's Monograph on the Cyprceidce. 491 



tumid, rather irregular, white, with scattered largish round pur- 

 ple spots. The mouth wide, orange colour ; teeth white, those of 

 the inner lip small, close, nearly equal ; of the outer lip large, dis- 

 tant, extended over the lip nearly to the margin, forming promi- 

 nent ribs ; columella flattish, front parts deep, plaited ; inside 

 purplish white. Axis -|-§, diameter J? 5 of an inch. 



When this beautiful species is young, the shell is nearly cylin- 

 drical, for the margin is scarcely thickened, and the spots are 

 paler ; but it is even then soon distinguished by its mouth and 

 back.
