Distribution. — The extremely wide distribution of this small species 

 has been recorded in my Harvard paper; a large number of localities 

 in the tropical and temperate Atlantic, between lat. 37° 58' N.; long. 

 16° 21' W. and lat. 26° 58' S.; long. 44° 57' W., have been enumer- 

 ated in my paper on the Schizopoda from the Swedish Antarctic 

 Expedition (1913).

 Antarctic Ocean presented by Prof. D'Arcy W. Thompson and deter-
