* Thiele (1900, p.47–48) wrote: “Von einer Art hat Kieschnick eine Diagnose mit folgenden Worten gegeben (l. c., p. 530): … Ein Exemplar, worauf diese Beschreibung zuträfe, ist in der mir vorliegenden Sammlung Kükenthals nicht vorhanden, daher muss ich diese Diagnose Kieschnicks als offenbar irrtümlich einziehen“ Our translation: „Kieschnick gave a diagnosis of one species in the following words (l. c. p. 530): …(he here repeats Kieschnick´s text and then goes on): “There is no specimen fitting to this description in Kükenthal´s collection, which I have before me, I therefore have to withdraw the diagnosis as obviously erroneous. Presumably he described the spicules of a really present species of Erylus together with another sponge, which will be proved in the following. The species should not be described so far and so I call it Erylus nobilis.”
