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

 Trichiuridce." Jordan and Evermann. 



2 "From the Squamipinnes the Plectognathi are certainly descended." "The close connection of these groups leads 

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

 offshoot from the Squamipinnes.'' Jordan and Evermann. 



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



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