Typical specimens of this species were obtained at nine stations 

 with a rather different distribution from the preceding species, being 

 more widely scattered: Off Manila Bay; Bouro Island; Jolo Sea; north 

 of Celebes; Palawan Passage; and Patiente Strait. In depth these 

 range from 297 to 1,105 fathoms (543 to 2,021 meters). The bottom 

 temperatures where given range from 41.2° to 56.4° F. (5.1° C. to 

 13.5° C). 



Some of the specimens are very perfect and of large size. In a 

 few cases the bottom material is recorded as coral sand, rather an 

 unusual bottom condition for this species.
