Plankton-type. According to my notes and Ostenfeld's data 

 this species is a typical Sty liplank ton-form with essentially eastern 

 distribution. It has been seen only rarely along the N. coa.st of S. 

 America and not in the Florida Current. It enters the Atlantic west 

 of S. Africa, spreads from the Cape Verde Islands to the Azores and 

 occurs in May across the Atlantic^ between 40° and 5(J" N. It was 

 seen in June between the Shetlands and Iceland, in August at W. 

 Greenland and in September (1899) W. of Spitzbergen. I have 

 never found it in any collection from the Sargasso Sea, but Murray 

 & Whitting mention it from that region. — .S.
