This species is closely allied to erosa, but the wiiorls ar« 

 ^aid to be flatter, and apjjarently higher, since, if viewed 

 dorsally, the last whorl, it is stated, equals almost one-third 

 of the whole length of the shell, whereas in ero.sa it equ.ils 

 only one-fourth. The base of the b .dy-whorl in the latter 

 is abnost flat and circunisciibed by a distinct an;;le. In 

 tsclirichiii, on the contrary, the periphery and base are 

 rounded. The aperture is longer and oval, whilst in erosa it 

 is shorter and rounder. Animal and operculum unknown.
