Type by subsequent designation, Gray, Pioc. Zool. Soc. 

 (Lond.), 1847, p. 165 : Doris maculata. 

 Not Doto, Oken, Gottingen Gelebrte Anz., 1807, pt. 2, p. 1168.

 Type by original designation, Melihcea fragtlis, Forbes. 

 [Note. — Dotona was proposed for Doto preoccupied, as Idulia 

 had been commonly regarded as simply a misspelling of Idalia, 

 but reference to Leach's proof-sheets, printed in 1819, shows Idulia 

 to have been invented years before Idalia, so Ididia must be used.]
