98 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 22 



Goniada brunnea was first described off the Hawaiian Islands in 

 202-220 fms, but has been more widely recorded from other parts of 

 the eastern Pacific Ocean, in shallow depths to 600 fms (Hartman, 

 1950, p. 19). The present records extend the depth range to nearly 

 900 fms.
