DIPHYOPSIS DISPAR. 257 



No species of Galeolaria as yet recorded from the Pacific could be confused 

 with it. 



The locaHties from which the species is recorded, Eastern Tropical Pacific, 

 Bay of Biscay, and West Indies, suggest that it will be found widely distributed 

 over the warmer zones of all oceans. Though it has now been taken in twenty- 

 four hauls (seventeen of which were in the Bay of Biscaj') , only once has it been 

 found in a surface haul. On the other hand, the shallowness of most of the 

 Atlantic captures (fifteen from 100 fathoms or less, one from 250, one from 300, 

 all in open nets) shows that it belongs to the "epiplankton," though it is appar- 

 ently uncommon immediately at the surface.
