This fish was originally described from a specimen 5 feet long seen by Eafinesque at 

 Solanto, Sicily, June 15, 1808. It has since been observed at Nice, in the Adriatic and 

 at Malta and Elba, and at Cette, whence came the beautiful specimen which we Lave seen in 

 the Museo Civico of Genoa. 



Prof. Giglioli was the first to point out the interesting series of metamorphoses by 

 which Astroderimts and Diana develop into Auiionia and Luvarus. 



Lowe observed both young and old at Madeira, and Steindachner found it on the coast 

 of Spain. Two were thrown ashore on the Cornish coast in 18G6, and from one of these, 

 45 inches long, Day had made the excellent figure for his " Fishes of Great Britain and 

 Ireland."
