The seventh segment is furnished with four large tubercles in a transverse line, two on eitherside of the median line. The lateral parts of all the segments areproduced in narrow triangular lobes, with rounded extremities. The first segment of the abdomen has two large tubercles, one oneither side of the median line, and two smaller ones on either side ofthese, making six in a transverse row. The terminal segment isbroadly rounded posteriorly, with the apex slightly truncate. Onthe anterior portion are six prominent tubercles, four in a transverse For description of the male, female, and young of the first stage, see Schicedteand Meinert, Nat. Tidsskr.

Close to the lateralmargin on either side, and just below the middle of the segment, thereis a thick bunch of hairs. The inner branch of the uropoda is pointedat the extremity and extends but little beyond the abdomen. The outer
