 scarcely more than half the length of the end segment ; the latter as 

 long as the two basal segments combined. Total length, 2-2.4 mm.

 the proportions of the various parts of the body, and by the fifth 

 legs. Thus far it has been reported only from the northern Atlantic 

 on both the European and American sides.
