. The Danish Ingolf-Expedition. Scientific expeditions; Arctic Ocean. VNNELIDS. I 33. Kg. â 4- of the basal joint of the unpaired tentacle; their terminal filament is inconspicuous. The palps arc of usual length and shape, with a relatively short terminal filament. The tentacular cirri are rather short. While the palps are smooth, the tentacles and tentacular cirri are beset with sparcely spread clavate papillae of the usual form. The foot (fig. 141 is about as high as long; the notopodial branch some- what smaller than the neuropodial. The acicles are strong; the dorsal cirrus is medium length and slender, beset with sparcely spread papillae like the tentacles and the tentacular cirri. The ventral cirrus is rather short and of the usual shape. Segmental papillae are distinct; in the hindmost half of the body they are longer than in the front part. The dorsal bristles (fig. 15 a) are of the usual sword-shape in this genus. The transverse rows of spines are rather prominent, the spines themselves are rather stout but acute. The distal part of the bristle is devoid of spines of a length about corresponding with the case i H. imbricata. The ventral setae are rather different according to their position; the most ventral of them has a rather short end-leaf, the spines of which are very delicate, almost hairlike; the most distal of these spines differ from the others, being a stout and clumsy thorn diverging more from the longi- tudinal axis of the bristle than the others (fig. 15 /', c). The tip of the bristle calls to mind that in Harmothoe imbricata; the tooth under the apex is however relatively weaker. The most dorsally situated of the neuropodial setae have a considerable long endblade provided with a strong and abundant supply of spines; the tip of these bristles is straighter than that of the other ventral setae, the secondary tooth is stronger (fig. 15 d). The elytra which are relatively large, and seem to cover the dorsum in its whole breadth, are present to t
