Very characteristic specimens of this species have been noted at 

 13 stations in the area, ranging in depth from 12 to 138 fathoms (22 

 to 252 meters), the average 41 fathoms (75 meters). The bottom 

 temperatures at three stations ranged from 52.4° F. to 63.1° F. 

 (11.3° C. to 17.2° C); the average temperature 57.9° F. (14.5° C). 



All these specimens are in the region of the Archipelago, the most 

 of them about the Sulu Sea, in comparatively shallow water. It 

 does not seem to be common, however, at any of these stations, and 

 is not nearly as common as the other two species of this genus in the 

 same general area.
