spine If in head, longest soft rays 2\ in head; caudal 2^ in head, slightly 

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

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

 orange, deepest at base of dorsal; head and u;ipe 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 liead pakr; 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. lowilrostris ; soft rays of dorsal 

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

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

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

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

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

 mens from Clarion and Socorro islands, (J to 8 inches in length. (Jlarissi- 

 mus, very yellow.)

* The Linnrcan genus, Chcetodon. is ba.scd on various specie.s, chiefly of this family, the 

 Pomacentridce and Teuthidida;. Fiirskal, in 177r>, removed the latter elements to form 

 bis subgenera J^6»rfp/rf(// and Acaut/nn n.-<- r'nnacanthus and iZui«ca>U/(MS were removed 

 by Lacepede, and by Cuvier the gouu^ h a- liuiitud essentially to its present boundaries. 

 One of the two Linuican species, htrialuf, ami capistratus. mentioned by Cuvier must be 

 regarded as the type of Chcetodon. Of these striatus was chosen as type of Tetragonop 

 terus, which would apparently leave capistratus as the type of Chcetodon. The use by 

 Bleeker of Chcetodon for Pomacanthus is justified only by the peculiar rules of nomencla- 

 ture adopted by Bleeker. This code recognized pre-Linnasan genera, and made the first 

 species mentioned under a new generic name as the type of it.
