89. DENTEX MACROPHTHALMUS (Bloch). (Goggle-eye; Cachucho. ) 
Mediterranean Sea and neighboring waters, 
90. DENTEX DENTEX (Linnzeus). (Dentao; Deuton.) Shores of southern

XXI. NEMIPTERUS. 
Nemipterus Swainson, Nat. Hist. Fishes, etc., 11, 1839, 223 (filamentosus). 
_ Synagris Giinther, Cat. Fish, Brit. Mus., 1, 1859, 375 ( furcesus; not Synagris Bleeker). 
Dentex Bleeker, Systema Percarum Revisum, 1875, 278 ( filamentosus). 
Type: Dentex furcosus Cuv. & Val. 
Etymology: vjua, thread; zrepdy, fin. 
This genus contains some twenty species, very closely allied to the 
species of Dentex, from which genus it is not quite certain how they 
should be separated. All are Asiatic, except one, which is very imper- 
fectly known and may be a true Dentex. The name Nemipterus has 
priority over Synagris for this group.
