[Taxacom] holotype designation

Gary, your inference about Tindale is correct - although 1958 in this case
and the context is the same as you gave. For example for E. salvazi the
full quote(and placed in a separate paragraph) is "Loc. Laos: Thado, 6
June, 1915, R. Vitalis de Salvaza (type a male, unique, in Cornell
University Collection, lot 841)." So am I correct to understand that this
is "by original designation" rather than "by monotypy"?
