but the position of Sub-Tribe A is less certain, 

 their allies were for long associ- 

 ated with the Gadiformes, from 

 which they have been distinguished 

 by Boulenger [40]. 



The pelvic fins are placed in 

 front of the pectorals, being 

 'jugular' or even 'mental' in 

 position. The base of the pectoral 

 tin is usually vertical and ex- 

 tended. Frequently the foramen 

 lies not in the scapula, but between 

 it and the coracoid (Fig. 477, A). 

 The spines and scaling are gener- 

 ally reduced ; the more specialised 

 families become much modified 

 and give rise to some of the most 

 phantastic forms of fish. 



SUB-TRIBE A. Two of the 

 short flattened pectoral radials 

 rest on the coracoid, and some of 

 the anterior dermal rays on the 

 scapula, as in the Scorpaeniformes 

 (Fig. 477, A;. 



Family TRACK IJUDAE. The 

 Weevers have u subocular lamina 

 on the second suborbital, well- 

 developed pleural ribs and epi- 

 pleurals, the foramen between the 

 scapula and coracoid, and a long 

 opercular spine. The mouth is 

 large and protractile, the snout 

 very short, the spinous dorsal short 

 and separate, the tail lengthened 

 with a long soft dorsal and anal. 

 The pelvic fins have one spine and 

 five jointed dermotrichs. The air- 

 bladder has been lost, and the 

 small Cycloid scales are set in 

 oblique bands.

Family PERCOPHIIDAE. Differ 

 from the preceding in the disposi- 

 tion of the scales, the wide separa- 

 tion of the pelvics, and the position 

 of the foramen in the scapula (Fig. 

 477, B).
