Very flue and complete specimens, showing the prolocukim intjict, 

 were fomid at a number of stations in the region. 



It is worth nothig here that in the Atlantic H. friabilis was found 

 in comparatively warm waters, while H. suhnodosa was limited to 

 very low temperatures. As all these stations in the Philippine area 

 here noted have relatively high temperatures, the frequency of H^ 

 friahilis and complete lack of H. subnodosa is very significant. 



The localities for this species in the region include Cluna Sea, off 

 Hongkong; Palawan Passage; Jolo Sea; eastern Palawan; between 

 Leyte and Mmdanao; between Negros and Siquijor; north of Celebes; 

 off Bouro Island; and m Buton Strait.

Specimens of this species have been noted in material from 20 or 

 more stations in the region. A considerable number of these stations 

 were off the east coast of Luzon, in 310 to 569 fathoms (567 to 1,081 

 meters), bottom temperature, where recorded, 44.3° F. (6.8° C).
