This species, as might be expected, is very typical and finely de- 

 veloped at many stations, the most abundant and finest specimens 

 being found in comparatively shallow water. 



Of the 21 stations at which it is recorded, ranging in depth from 10 

 to 500 fathoms (18 to 914 meters), the average depth is 166 fathoms 

 (303 meters). It is most numerous and best developed about the 

 islands of the Sulu Archipelago in shallow water, usually under 20 

 fathoms (37 meters). It has also occurred in Verde Island Passage; 

 China Sea, off southern Luzon; east of Masbate; between Burias and 

 Luzon; and off Komblon.
