 highly specialized. One of the 

 best types is Exonaides (Fig. 84), 

 which, when it leaps out of the 

 water, parachutes for some distance 

 by means of its very large pec- 

 toral fins. 



The sub-order is not believed 

 to be homogeneous, for it con- 

 tains such aberrant forms as Be- 

 lone, a fonn reseml^ling superficially 

 the Gar-Pike, and sometmies given
