STOMIATOIDS.THE BEAKED SALMON. 37 



STOMIATOID FISHES. 



(Family^ Stomiatidce.) 



THESE are large-mouthed and large-eyed fishes frequenting 

 the ocean depths ; some being known from a depth of nearly 

 2,500 fathoms. In some the body is naked, while in others 

 it is scaly. In most of the species, the luminous organs 

 known as "photophores" are well-developed. Their enor- 

 mous mouths are characterized by a most formidable array 

 of teeth. 



At least two species of these Stomiatoids* are known 

 from our waters ; one having been obtained by the "Chal- 

 lenger" at a depth of 2,440 fathoms off the North-west Coast 

 of Australia, while the other was obtained by the same 

 vessel off the coast of South Australia at a depth of 2,150 

 fathoms.
