This species was known to Risso, who had in his collection the speci- 

 men which afterwards served Be Filippi as a type and which is now 

 in the Turin Museum. A sketch by Kisso of this fish, to which he 

 never gave a name, is given in " ( )ceanic Ichthyology." The Turin speci- 

 men was examined by Prof. Giglioli in 1882; it is 160 mm. long and has 

 the following radial fornnila: D. 29/1; A. 35. 



Prof Uigiioli has three specimens in his collection at Florence. We
