The distribution of this species has been thoroughly dealt with 
by Fowler (1906) and Ritter-Zåhony (1910 and 1911b). The 
Species occurs in all oceans. In tropical and subtropical regions it 
Js found in the mesoplankton exclusively; in the temperate parts 
of the seas it may also occur in the lower epiplankton, and in 
Cold areas it may even be met with at the surface. As to the 
Vertical distribution in the waters near Spitzbergen Ritter-Zåhony 
States (1910), that the species has its maximal occurrence between
