There is a single specimen of this species from Albatross station 

 D5201, Sogod Bay, southern Leyte, in 554 fathoms (1,012 meters). 

 This is very similar to the specimens I have previously figured.^

Both attached and free specimens have occurred in the dredgings, 

 but the species has been noted at but three stations: D5236, 494 

 fathoms (903 meters), eastern coast of Mindanao; D5268, 170 fath- 

 oms (311 meters), Batangas Bay; and D5301, 208 fathoms (381 

 meters), China Sea. The bottom temperature at the latter station is 

 given as 50.5° F. (10.2° C), for station D5236, 41.2° F. (5.1° C), and 

 none is recorded for D5268.
