Reophax pilulifera H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 

 292, pi. 30, figs. 18-20.— CusHMAN, Bull. 71, U. S. Nat. Mua,, pt. 1, 1910, p. 85, 

 figs. 117, 118 (in text). 



This species has occurred at 13 stations in the region, usually but 

 few specimens occurring at any station. 



The stations are all in less than 1,000 fathoms (1,829 meters), 

 excepting one, D5637, in 1,560 fathoms (2,853 meters), while from 

 the dhallenger records Brady makes the statement that it "appears 

 to be peculiar to deep water," most of the records from that material 

 being of considerable depths. 



The following localities are represented by the specimens: Sulu 

 Sea, off southern Panay; China Sea, off Luzon; east coast of Luzon; 

 between Siquijor and Bohol Islands; Sibuko Bay, Borneo; and be- 

 tween GiUolo and Makyan Islands. 



After an examination of material from one of the original stations 

 in the Porcupine dredgings it seems probable that many of the 

 records for this species represent other species. The Philippine 

 specimens are smaller than those of the Porcupine material and are 

 not typical.

A single specimen was found in material from D5621, between 

 GiUolo and Makyan Islands, 298 fathoms (545 meters). At D5639, 

 Molucca Sea, 1,560 fathoms (2,853 meters), it was abundant but most 

 of the specimens were broken.
