Re: Placo- or Plakobranchus?

Dear Bill,
    
There is an interesting story here and because Placobranchus is a misspelling (technically an invalid emendation), I have changed (actually reverted) to using Plakobranchus for the genus and Plakobranchidae for the family. Kathe Jensen (1997: 62) gives the following explanation:
    
Hasselt's (1824) original description of Plakobranchus ocellatus was published in a Dutch journal Algemeene Konst- en Letterbode but it was translated into French the same year by M. Boie who, in error, transcribed Plakobranchus as Placobranchus. It is this translation, "Extrait d'une lettre de J.C. van Hasselt au Prof. van Swinderen sur les mollusques de Java", Bulletin des Sciences Naturelles et de Geologie, vol. 3, 1824, pp. 237-248, which is usually quoted as the original source of the name. The misspelling Placobranchus appeared on page 240 of Boie's translation.

Happy New year,
    
Richard

Thanks Richard,
I hoped someone could help us out. Is Kathe's reference a special musuem publication? I don't think I have seen it.
