Although the number of stations for this species is large, there are 

 no stations among them from the region south of the Philippines 

 themselves. It occurred in general in the following localities: Off 

 Formosa; China Sea, off western and southern Luzon: Baylayan Bay 

 and Verde Island Passage; between Marinduque and Luzon; between 

 Bui-ias and Luzon; off Romblon; east of Masbate; east coast of Luzon; 

 off northwestern Panay; between Panay and Negros; Tanon Strait, 

 east coast of Negros; between Siquijor and Bohol; Sogod Bay, south- 

 ern Leyte; eastern Illana Bay, southern Mindanao; off Jolo; off Tawi 

 Tawi; off eastern Palawan and Palawan Passage. These localities 

 cover the area fairly well. The range in depth is from 12 to 805 fath- 

 oms (22 to 1,472 meters), with a few specimens from Little Harbor, 

 near Manila, in a few feet of water; the average depth of all stations, 

 318 fathoms (582 meters). Bottom temperatures range from 40.6° 

 to 63.1° F. (4.70° to 17.2° C), with the average 51.3° F. (10.7° C). 



The specimens as a rule were rather small, with little or no raised 

 surface ornament, and the usual brownish tinge to the translucent test.
