The range of this species is remarkable, extending as it does geo- 

 graphically from lat. 9 3' 24" N. and from long. 79 37' E. (according 

 to Koehler) to lat. 54 33' 30" N. and to long. 130 34' W., and 

 bathymetrically from 53 fathoms to 876. But Koehler has made a 

 serious blunder in saying that the species was taken by the Challenger 

 "entre les iles Philippines et les iles Carolines," for the only recorded 

 Challenger station is 232, not far from Yokohama, Japan.
