At the above-named Station a Polynoid-vvorm was dredged, that possesses only some 

 of the anterior scales ; it has a length of 12 mm. and consists of 38 segments, whereas the 

 number of elytra amounts to 15. The head (PI. XX, fig. 4) shows a median groove on the 

 dorsum and from its anterior part a short tentacle arises with a stout basal part; its distal 

 joint, not much longer than the basal one, is dilated in its inferior part and abruptly ends 

 with a filiform tip. The lateral antennae are only somewhat longer, also terminating in a 

 filiform tip. The palps are rather stout, tapering distally, with a filiform tip, darkly pigmented 

 like the head, except a longitudinal pale stripe over their dorsal side. Indistinct eyes He in 

 front of the posterior margin of the head. The scales (PI. XX, fig. 3) are reniform, their un- 

 covered part being blackish and beset with rather large conical spines, whereas their posterior 

 margin is fringed with rather long, cylindrical papillae ; only on the covered part of each scale 

 there are small tubercles. No dorsal tubercles are present. The parapodia have a long dorsal 

 cirrus, furnished with rather long papillae and extending beyond the bristle-fascicle ; the ventral 

 cirrus is minute, smooth and does not reach the distal extremity of the foot. The notopodium 

 has a rounded, ear-shaped edge; its anterior lip is short, straightly cut, whereas the posterior 

 one is elongated, pointed. Its bristles are fringed up to a short distance from the tip, that is 

 acutely pointed. The n europodium has a triangular, elongated anterior lip, enclosing the aci- 

 cula ; its bristles are longer, bifid, with laciniated whorls on the dilated distal part. 



The species appears to be allied to Lao^isca yokohamicnsis^ but it does not show the 

 rapid diminution of the body posteriorly, that occurs in the genus Lagisca ; also as the last 

 scale is situated on the 32"^ segment, no great part of the body can have been uncovered.

At the above-named Station a small worm was dredged, that must be identified with 

 Gattyana pallida^ specimens of which were captured by the Deutsche Tiefsee Expedition south 

 off Pulu Nias, at the depth of 616 M. It measures 21 mm. in length and has 37 segments. 

 The species is characterised by its reniform elytra, that have the scar of attachment situated 

 near their concave margin; the Siboga -specimen possesses 15 pairs of elytra, whereas Ehlers 

 mentions 16 pairs. The elytra show an areolate structure, especially in the vicinity of the 

 margin ; these cavities are covered by the thin epidermis-layer only and are distinctly visible 

 through this layer. The blunt tubercles on the upper surface of the elytron have a small 

 round cavity ; the filiform papillae of the margin are dilated distally.
