C. tripos var. arctica Exp. — I do not, as Dr. Aurtvituius, include under this name 
also the var. longipes, which | find always easy to distinguish from the original form, 
figured in the Microgeologie and by Cravarbpr and Lacamann. The var. arctica occurs 
frequently, sometimes in immense number, in the Labrador current, in Davis strait 
and around Spitzbergen (optimum salinity 34 p. m.). It belongs thus to the tricho- 
plankton chiefly, but occurs also in the sira-plankton. The var. longipes, on the con- 
trary, is a more neritic form, which occurs in the spring along the whole Norwegian 
coast-line, around Scotland and in Skagerak. It belongs to the northern neritic plankton.
