Group OAPROIDBA. 



A group of doubtful affinities, containing the single family Caproidw. 

 It has the ventral tins normal, the post-temporal aduate to the skull, and 

 is, in many respects, similar to the Squamipiniies. 



Family CLXIII. CAPROID.E.* 



(The Boar-fishes, j 



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

 of head scaly ; preorbital and jireopercle more or less serrate or armed ; 

 opercle small ; gills normal ; gill membranes separate, free from isthmus ; 

 top of head bony ; premaxillaries very protractile, the posterior process 

 very long; mouth moderate, the lower jaw projecting, the teeth very 

 small ; lateral line not extending on caudal ; dorsal fin long, the stout 

 spines separated from the soft i-ays by a deep notch; dorsal spines not 

 graduated; anal fin with 3 spines separated by a notch from the soft rays, 

 the first spine longest ; soft part of anal as long as soft dorsal ; ventrals 

 I, 5, the spine strong, inserted below pectorals; caudal fin rounded, on 

 a moderate peduncle. Upper limb of the post-temporal widened at its 

 distal end, which aftbrds a very firm attachment; the lower limb short 

 and thidk. The supra-clavicle long and slender, its posterior edge sharply 

 serrate, the serrations standing out above the surface of the skin. Ver- 

 tebrjB in normal number, 10 + 13 = 23 (in Capros). Two or 3 species, 

 arranged in 2 genera, and living in rather deep water. Capros aper, the 

 Boavfish, superficially resembles the John Dory, Zcks faber, and is com- 

 mon on the coasts of southern Europe. This family, like the preceding, 

 is of doubtful affinities. It is only remotely allied to the Zeidw, and its 

 relationship to the Carangida' or other Scombroid forms is not evident. 

 AntUjonla bears much superficial resemblance to the Epliippid(v, a resem- 

 blance probably arising from real affinity, as is shown by the form and 

 attachment of the post-temporal. An extinct genus, Proantitjoma, is said 

 to connect Antujonla with Capros. {Capridw, Lowe, Fishes of Madeira, 

 1843, XII.) 



ANTIGONIIN^ : 



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



h. Teeth slender, in jaws only; anal spines strong. Antigonia, 654. 



* Called Caproidce by Dr. Gill to distinguish the group from Capridce, the family of 

 Oapra, the goat.
