of cilia round the mouth as a guide, the specimens come nearest to Beroe flemingii. 

 They do not, however, quite agree in shape, and the lateral canals from the meridional 

 canals do not communicate with the stomodseal canals. Miss Moser states that the 

 Sihoga specimens are identical with Pandora flemingii of Eschscholtz. This species 

 Eschscholtz named after the English zoologist John Fleming. Miss Moser, 

 however, has changed the specific name to pandora, wishing to retain the generic 

 name Pandora as a specific name in honour of Eschscholtz. The changing of the 

 specific name of this species is certainly contrary to the International Rules on 

 Nomenclature, and consequently the specific name pandora is invalid.
