The records for this species show that it is most common in warm 

 shallow water, especially in the southern part of the Archipelago. 

 The stations range from 18 to 277 fathoms (33 to 507 meters), only 

 two of them, however, being greater than 37 fathoms (68 meters). 

 These are D5212, 108 fathoms (198 meters), east of Masbate Island, 

 and D5o76, 277 fathoms (507 meters), north of Tawi Tawi. At both 

 of these stations specimens were rare. In aU cases the bottom 

 temperatures were relatively high— 59.9° F. (15.5° C), 53.3° F. 

 (11.8° C), and 75.7° F. (24.2° C).
