spine If in head, longest soft rays 2| in head ; caudal 2J in head, slightly 

 lunate, upper lobe longer; third anal spine very long, much longer than 

 second, If in head; pectoral 1 in head; ventral \\ in head. Color bright 

 orange, deepest at base of dorsal ; head and nape abruptly black to level 

 of lower point of eye, below this point reddish pearly ; breast and lower 

 jaw nearly white; preorbital bones paler than cheeks, which are mottled 

 with brownish; median region of top of head paler; pectoral slightly 

 dusky; dorsal and anal colored like body, the last rays of anal with a 

 large black blotch, vertically oblong, its longest diameter a little greater 

 than diameter of eye, not ocellated as in F. longirostris; soft rays of dorsal 

 and anal blackish at tip, the very edge pale; caudal abruptly blackish. 

 This species is extremely close to F. longirostris, which is common in the 

 East Indies. The American species differs, however, in the deeper body 

 and the much larger anal spot, which is almost round in the East Indian 

 species. Rocky Islands, off the west coast of Mexico; numerous speci- 

 mens from Clarion and Socorro islands, 6 to 8 inches in length, (flarissi- 

 mus, very yellow.)

* The Linnrcan genus, Chcetodon, is based on various species, chiefly of this family, the 

 Pomacentridce and Teuthididce. Forskal, in 1775, removed the latter elements to form 

 hissubgenera Abudefdvf and Acanthurus.- Pomacanthus and Holacanthus were removed 

 by Lacepede, and by Cuvier the genus was limited essentially to its present boundaries.
