 34. STYLOCHEIRON ELONGATUM G. O. Sars 



Occurrence 



Remarks. — This species is comparatively rare but widely distrib- 

 uted in the tropical oceanic area. It is a deep-water form, only a 

 single specimen occurring in 46 hauls taken above 400 meters, while 

 it occurred in 50 per cent of the hauls taken below that depth. Its 

 maximum of distribution seems to lie between 400 and 700 meters. 



35. STYLOCHEIRON SUHMH G. O. Sars 



Occurrence 



Remarks. — This species is widely distributed in the tropical oceanic 

 area, but never very abundantly. It occurred in about an equal 

 number of hauls above and below the 200-meter line, but whereas 

 104 specimens were taken between 200 meters and the surface, only 

 20 specimens occurred below that depth. It is most abundant 

 between 100 and 200 meters.
