coast of Japan several well-preserved species, which in many regards agree with the species 

 tVom Ceram. I think, that Polynoc crinoidicola Potts must be ranged also in the same genus. 



1. } Scalisctosus ccranwnsis Mc. Intosh. 



Mc INTOSII, Challenger Annelida Polychaeta, p. 103, PI. Xa, figs. 13 and 14. 



Stat. 267. 5° 54' Lat. S., I32°56'.7 Long. E. East of Great Kei Island. Depth 9S4 1\L i in- 

 complete .specimen. 



Length 10 mm.; segments 35. Presumably 15 elytra. 



At the above-named .Station a worm was dredged, that with regard to its bristles much 

 asrees with Scalis. ccramensis : unfortunatelv Mc Intosii had only a single badly preserved 

 specimen at his disposal and therefore coiild not give a detailed description. Our specimen 

 also lacks the elytra and cirri. The frontal peaks of the prostomium are very distinct ; palps 

 and antennae are absent. On each side of the head two large eyes are situated ne.xt to each 

 other, the anterior of them lying laterally, the posterior one in front of the posterior margin 

 of the head. 



The parapodia have both lobes well-developed. The neuropodial lobe has its anterior 

 lip very much elongated, with a filiform tip, extending beyond the point of the acicula, that lies 

 enclosed in its base; its long and slender bristles have the distal end dilated, slightly falciform, 

 obviously serrulated along both edges, with a small tooth below the tip, that however is 

 not separated from the shaft by a semilunar cusp as in other species. The dorsal lobe is also 

 pointed and elongated, but hardly reaches to half the length of the ventral one ; its bristles 

 are stout, half as long as the ventral ones, .slightly curved and furnished with three spines 

 instead of with the usual fringes. 



2. Scalisetosus (Polynoe) crinoidicola Potts. PI. XVI, figs. 6 — 8; PI. XXI, fig. i. 



PoTïs, loc. cit. p. 337, PI. XVin, fig. 10; PI. XX, fig. 30; PI. XXI, figs. 39—41. 



Stat. 164. t°42'.5 Lat. S., i30°47'.5 Long. E. South off Salawatti. üepth 32 M. i specimen. 



xA. small worm, mea.suring only 12V., mm. in length; its dorsum is brownish black, 

 somevvhat paler in the median line, with two narrow white transverse lines over each segment. 

 The parapodia as well as the ventral side of the body are yellowish, buff. The eyes are sur- 

 rounded by a pale ring; the anterior pair are the larger, strongly protuberant. That they should 

 "be raised on a distinct eminence" as mentioned by Potts, could however not be confirmed. 

 The palps are somewhat longer than the latera! antennae; both are dark coloured, with the 

 slender e.xtremities colourless. The median antenna is lost, like in the specimens ot Potts. 

 The tentacular cirri are unequal in length ; the dorsal ones longer than the palps, nearly of 

 the .same length as the proboscis. Of the fifteen pairs of elytra only a single one was left ; it 

 is circular, except a small notch near the eccentrical scar of attachment, from which several 

 nerve-trunks are ramifying towards the circumference. The surface of the elytron is smooth, its 

 border without fringes; at the inferior side it was partly covered with a layer of pigment-cells
