interest. The L,e of the maxilhilae show, however, some variation. In one specimen a single very 

 short hairy seta, a longer one and 5 very long ones were present on each side; in another specimen 

 1 fairly long -f- 5 very long were found on the left side, but 2 short -j- 5 long on the right side; in 3 

 specimens 2 short -j- 5 long setae were found on each side, and in one, on the left side, in addition to 

 the 5 long ones, one fairly long and one very short seta. The basipodite has 5 setae, the Ri I 3, Ri II 

 4 (one very delicate), and the Ri III 3 setae. 



The pes I has the articular membrane between Re I — II fairly well developed anteriorly (text- 

 figs 48 b — c), and the Se Re I is fairly well developed. The Se Re II scarcely extends to the end of 

 the short Se 1 Re III, and the Se 2 Re III extends somewhat beyond the middle of the third division 

 (cf. Wolf en den's fig. 9, p. 134). The epistoma, anterior surface of the labrum, and the labial lobes

seem in main features to be like E. norvegica; the oral surface of the labrum is somewhat different 

 from E. norvegica, as seen by comparing figs 6 a and 3 a; the lateral anterior group has about 60 rather 

 strong short spines, the groups 1—6 are more regularly placed. The area in front of the lamina labi- 

 alis differs by the less square, more rounded, lateral group of short hairs. 



Y^ (St. V). Size 8*3 mm. ; anterior division 6 mm.; urosome 23 mm. 



The lateral corners of the thorax are regularly rounded; in other respects, except the usual ones, 

 this stage is scarcely different from the adult females (text-fig. 48 f). 



Occurrence. This species was gathered at the following stations by the Ingolf Expedition.
