species, closely related to .tlie Ch(ctodonfs, but said to show important 
dittereuces in the skeleton. Fishes mostly of large size, in warm seas, 
sometimes entering rivers.

(Lacep&de, Hist. Nat. Poiss. iv, 50.1, 1801: type Clmtodoa phiniicri B\och.= Chcctoclon 
fahcr Brouss.) 
Body much elevated and compressed, its outline nearly orbicular, the 
anterior itrofile nearly vertical. Scales small, 5o-70 in the course of the 
lateral line. Jaws about equal; no teeth on vomer or palatines; teeth 
on jaws slender, somewhat movable; preopercle finely serrulate. Bran- 
chiostegals C. Dorsal fins 2, somewhat connected, the first of usually 
spines, the third of which is elongate ; anal spines d, small, the second 
the longest; ventral with a large accessory scale. Pyloric cceca 4-0. 
American, distinguished from the Asiatic genus Uphippus by the very 
much smaller scales. {yairoSwv^ Chtetodon; <5;^, two; Tzzepir^^ fin, the

002. C. fabes* (Brouss.) J. & G. — Angel-fish; Porgee. 
Grayish ; a dusky band across the eye to the throat ; a second similar 
band, broader, beginning in front of the dorsal and extending across the 
base of the pectoral to the belly; a third band, narrower, extending to 
the middle of the sides, from the base of the fourth and fifth dorsal 
spines; a fourth broader band from the last dorsal spine to the anal 
spines, the remaining bands alternately short and long; all of these 
bands growing obscure and disappearing with age; ventrals black. 
Vertical fins low in the young, lalcate in the adult. Third dorsal 
spine nearly as long as from eye to edge of preopercle, its membrane 
blackish; chin with a row of pores; preorbital nearly as wide as eye; 
])ectoral considerably shorter than ventral, the first soft ray of the latter 
filamentous. Head 3-34; depth I 4 . D. VIIl-I, 20; A. HE, 18; Lat. 
1. GO; cceca 4-6. L. 2 feet. Warm seas; north to San Diego and (New 
York; abundant on our South Atlantic coast; an excellent food-fish. 
Very large specimens, which we su])pose to be old individuals, but which 
may possibly be a distinct species {Ephippus gigas Cuv.), have the occi- 
pital crest and anterior interhaimals developed in thick bony masses.
