RESULTS 



These records definitely establish the fact that this 

 species is a pelagic, surface, oceanic, and mainly trop- 

 ical form. In both the Atlantic and Pacific oceans it was 

 not captured at any station north of latitude 40° north. 

 There were no stations south of latitude 40° south in 

 either ocean. It was particularly abundant between lati- 

 tudes 20° to 40° south and longitudes 80° to 100° west. 

 It was never taken in any of the townet hauls made in 

 any of the harbors and anchorages in the islands of the 



Pacific, but always in the open sea away from land. Of 

 the above records, iorty-eight (or eighty per cent) were 

 from surface hauls, six from 50 m, five from 100 m, 

 and one only from 1000 m (the specimen, a very young 

 one, in all probability caught as the net was hauled to 

 the surface). These facts clearly show that S. thomp- 

 sonii frequents the upper 100 m of water and is mainly 

 a surface form.
