and slightly produced below. The anal somite is fused with the furcal rami, of which sometimes the 

 left and sometimes the right is the longer. The structure of the legs and of the labrum is scarcely 

 different from that of the female. 



Jc^ (V). The male of this stage is scarcely different from the female except for the four 

 abdominal somites (text-fig. 9 f) and well developed fifth pair of legs, as previously described. Wol- 

 fenden (1904 p. 113) has, with some doubt establishud the young male of this species as a new one 

 Ezic. atlanticus^ because "the larger furcal segment and longest tail seta are on the left side, instead 

 of the right side", and on account of the not retrogi'aded oral organs. 



As, however, the former assumption is wrong, because not only males and females but also 

 young specimens have the longest furcal branch now on the right and now on the left side, and as 

 the latter is a general phenomenon in the young males, the species must vanish. 



.1!^ (IV). Size: 3-8 nun. In general structure this stage is like the preceding one, but the urosome 

 consists of 3 somites, of which the two first are of almost equal length and distinctly shorter than 

 the third one, which is fused with the furcal rami, on the left side being the longer in both specimens 

 examined. The ovaries were well developed though less so than in the preceding stage. 



Occurrence. The Ingolf has taken this species only at a single station in I)ennu^rk Strait.
