 (Fig. 479) ; the pelvic bones, cleithra, and postclavicles are expanded to

usually perforate, but often much reduced (Fig. 480). The pelvic fins 

 have a spine, and four dermotrichs, but are liable to reduction. The 

 body has a short trunk, large head, and long tapering tail ; both the 

 anal and the dorsal fin are usually lengthened, the latter often reaching 

 to the head and giving rise to separate cephalic rays.
