* Breitfuss in his Catalogue [3] puts this specimen down as " Levcosoletiia 

 hotryoides" and since the name Leucosolenia is used by him to denote Ascons in 

 which monaxon spicules are lacking, it follows, either that he did not examine the 

 specimen, or that he overlooked the very conspicuous monaxons.
