Brady in the Challenger report records this variety from off the 

 Philippines in 95 fathoms (174 meters). I have noted it in material 

 dredged at D5133, Sulu Sea, off western Mindanao, 38 fathoms (69 

 meters); D5259, off northwestern Panay, 312 fathoms (571 meters); 

 bottom temperatm-e 49.3° F. (9.6° C); D5300, China Sea, vicinity of 

 southern Luzon, 265 fathoms (484 meters); and D5438, west coast 

 of Luzon, Manila Bay to Lingayen Gulf, 297 fathoms (543 meters), 

 bottom temperatiu-e 46.2° F. (7.8° C). The typical form of the species 

 was also found at station D5300.

This species has been found at several stations. From these few 

 records it would seem that it is a fairly common species in the region, 

 as the most of the washed material did not contain small forms. 

 The specimens found were of the form without the apical spine, 

 with the basal reentrants few but distant. 



The localities include stations between Panay and Negros; off 

 northwestern Panay; Chhia Sea, off Hongkong and off southern 

 Luzon; off Jolo; and to the southward in Buton Strait and Macassar 

 Strait.
