 Extremes of adaptation in the existing bony 

 fishes (Teleosts) of the Abyssal Zone of 

 the Oceans. Although man\^ different or- 

 ders of Teleosts are represented, each type 

 has independenth^ acquired phosphores- 

 cent organs, affording a fine example of 

 the law of adaptive convergence. The 

 body form in these fishes is of great 

 diversity. i. Thread-eel, Nemichlhys
