Summary:

Has sent copy of his paper on the Papilionidae. Regrets complications of synonymy arising from Felder publishing ARW's new discoveries as part of Felder's Voyage of the Novara. This produces issues as to priority of names. Includes concordance list of Lepidoptera species described by both Felder and ARW.
