The Apodes, or Eel-like Fishes 



The LipogenyidcB have a round, sucker-like mouth, with 

 imperfect lower jaw, but are otherwise similar. Lipogenys 

 gilli was dredged in the Gulf Stream. 



FIG. 118. Notacanthus phasganorus Goode & Bean. Grand Banks. 



Dr. Boulenger has recently extended the group of Heteromi 

 by the addition of the Dercetida, Halosauridce (Lyopomi), and 

 the FierasferidcB. We can hardly suppose that all these forms 

 are really allied to Notacanthus.
