  After I had written my articles I realized the columellar plaits of
the smaller unicolored Scaphellas are more similar to the plaits
belonging to Scaphella junonia.  I also point out that this suggests the
subgenus of Scaphella "Clenchina" is invalid.
  Emerson and Old belived this subgenus was trivial based on the
comparison of radula charactaristics of S. contoyensis, S. evelina and
S. junonia.
