The color description of plexa is rather indefinite as only the 
color of the body is mentioned by Say and this is not of a constant 
and uniform color as distinctly indicated by the words, “more or 
less tinged with yellow.” By omitting “of which” Parshley gives 
a different meaning to the portion of the description which de-
