ventrals long; middle rays of dorsal and anal longest. Color grayish. 

 Open Atlantic. Known from a single specimen, 1 inches long. (Cuvier & 

 Valenciennes. )

 Atlantic ; GuNTHEK, Cat. Fishes, i. 214, and n, 396; GOODE & BEAN, Oceanic Ichth., 228. 



Oreotoma coniferum, CUVIER & VALENCIENNES, I c., pi. 99; same type; a slip arising from 

 nn corrected proof sheets. 



Group GAPROIDEA. 



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

 It has the ventral fins normal, the post-temporal adnate to the skull, and 

 is, in many respects, similar to the Squamipinnes. 



Family CLXIII. 



(THE BOAR-FISHES.) 



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 membranes separate, free from isthmus ; 

 top of head bony ; prernaxillaries 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 rays 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 affords a very firm attachment; the lower limb short 

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

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

 tebra in normal number, 10 -f- 13 23 (in Capros). Two or 3 species, 

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

 Boarfish, superficially resembles the John Dory, Zeus faker, 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 Zeidce, and its 

 relationship to the Carangidce or other Scombroid forms is not evident. 

 Antlyonia bears much superficial resemblance to the Ephippidts, a resem- 

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

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

 to connect Antiyonla with Capros. (Capridw, Lowe, Fishes of Madeira, 

 1843, xn.) 



ANTIGONIIN^E : 

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



&. Teeth slender, in jaws only; anal spines strong. ANTIGONIA, 654. 



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

 Oapra, the goat.
