This is a fish of very singular appearance and beauty. The body 
is of a lengthened form, compressed and gradually tapering towards 
the tail, which terminates in a long slender filament. The head is 
large, thick, and ascending in front into a pyramidal form : each 
jaw is furnished with a pair of broad laminae, which are crenulated
