NO. 1296. JAPANESE CH.^TODONTID.E— JORDAN AND FOWLER. 521 



Family II. ANTIGONIID.E.^ 

 BOARFISHES. 



Body compressed and elevated, covered with small, ctenoid scales; 

 sides of head scaly; preorbital and preopercle more or less serrate or 

 armed; opercle small; gills normal: gill-mem])ranes separate, free 

 from isthmus; top of head bony; premaxillaries ver}' protractile, the 

 posterior process very long-; mouth moderate, the lower jaw project- 

 ing; the teeth A'er}" small ; lateral line not extending on caudal; dorsal 

 tin long, the stout spines separated from the soft rays b}- a deep notch; 

 dorsal spines not graduated; anal tin with three spines separated by a 

 notch from the soft rays, the first spine longest; soft part of anal as 

 long as soft dorsal; ventralsl, 5, the spine strong, inserted below pec- 

 torals; caudal fin rounded, on a moderate peduncle. Upper limb of 

 the post-temporal widened at its distal end, which atl'ords a very firm 

 attachment; the lower limb short and thick. The supraclavicle long 

 and slender, its posterior edge sharply serrate, the serrations stand- 

 ing out abov^e the surface of the skin. Vertebra in normal numl)er, 

 10+18 = 23 {in Capros). Species few, arranged in 2 genera, living in 

 rather deep water. Capros apei\ the Boarfish, superficially resembles 

 the John Dory, Zeus faher, and is common on the coasts of southern 

 Europe. This family, like the preceding, is of doul)tful affinities. It 

 is only remotely allied to the Zeidx^ and it has no relationship to the 

 Carangidm or other Scombroid forms. A)itl(/o)tia ])ears nuich super- 

 ficial resemblance to the Ephlppiddc^ a resemblance doubtless arising 

 from real affinity, as is shown by the form and attachment of the 

 post-temporal. An extinct genus, Proantigoida^ is said to connect 

 Antigonia with Capros. 



a. Lateral line complete. Body deeper than long, covered with rough scales. 

 h. Teeth slender, in jaws only; anal spines strong Atifigonia, 4.

 (r^^hescens). 



Body very deep, the depth much greater than the length of body, 

 which is excessively compressed and covered with moderate-sized, 

 firm, rough ctenoid scales; profile from nape to dorsal very steep and 

 nearly straight. Surface of head above with rough bony stria?; pre- 

 opercle and suborbital bones armed with slender antrorse spines; 



nVe use the name Antigoniiihe in preference to ('apridie, as Caprid:r, derived from 

 Capra, is applied to the family of Goats. Caproidse used by Gill seems liardly 

 admissi])le.
