 It has also occurred in typical form at D5112, China Sea, off south- 

 ern Luzon, 177 fathoms (324 meters); D5114, in 340 fathoms (620 

 meters), off Verde Island Passage; D5201, Sogod Bay, southern

 p. 416, pi. 52, figs. 14-17.— Egger, Abh. kon. bay. Akad. Wiss. Miinclien, CI. ii, 

 vol. 18, 1893, p. 291, pi. 8, fig. 103.— Goes, Bull. Mus. Comp. Zool., vol. 29, 1896,

This species is only known from comparatively deep water, and 

 therefore it is not expected in any quantity in the Philippine ma- 

 terial. The only record is from Albatross station D5257, southern 

 Mindanao, in 28 fathoms (52 meters) proving an exception to the 

 general rule.
