* Pellona is the Spanish name of Pdloua Jlaripinnis at Buenos Ayres, apparently from pelon, 

 bald, in allusion to the caducous scales. 



If "typonyms," or new generic names based on the indication of a type, without descrip- 

 tion, are to be rejected, the name Pellona should take the place of llisha.
