. The Danish Ingolf-Expedition. Scientific expeditions; Arctic Ocean. only the limitation between Re I—II indicated, where the mnscle is fastened inwards; the articulation between the Re II and III is well marked anteriorly, but only indistinctly so posteriorly (text-fig. 54 e).

The epistoma and the anterior surface of the lahruDi are scarcely different from those of E. norv. The oral surface of the labruiii (fig. 11 a) a b c e shows a distinct difference from that of E. norv.^ as is realised by comparing fig- ures; the most characteristic feature is the lateral position of the first group, in front of which, behind the marginal fringe, a granular area is found. The usual spinous area behind the median spot Nr. 4 is wanting. The laiiii/ia labialis is, as seen in fig. II b, somewhat different from E. norv., but more interesting is the large lateral group of hairs almost completely fused with the median group, situated in front of the lamina. The lobus labialis has the posterior lateral group well developed. d*. Size: 4-8 mm.; anterior division (2'2 + i'4) = 3'6 nmi.; urosome 1-2 mm. The body is rather clumsy, and about 3 times as long as the urosome; no dif- ference was found between the lateral corners on the right and left side, and no tooth was observed.
