'"Remotely related to the Scoiubriform fishes, and perhaps derived from the same ancestral stock as the 

 Trichiuridm." Jordan and Evermann. 



="From the Sqiui mi pinnes the Pleclognathi are certainlj' descended." "The close connection of these groups leads 

 us to subordinate the Pleclognathi to the Acanthopteri and to place its 3 sub-orders in their natural position as an 

 ofifshoot from the Squamipinnes." Jordan and Evermann. 



'"Closely allied to the Balistidoe, difTering chiefly in having the first dorsal represented by a single spine, 

 behind which is sometimes a rudiment." Jordan and Evennann.
