are slender, smooth, tapering distally and extending nearly as far as the bristles of the second 

 segment. The neuropodium of the second segment has a club-shaped prolongation ; its bristles 

 are articulated, with a very slender process with curved tip. The dorsal cirrus of the third 

 segment has a short basal part and a long whip-shaped terminal portion, that reaches as 

 far as the palp. In the neuropodium of the succeeding feet the central bristles of the fascicle 

 are furnished with a rather long, not stout, bifurcated terminal process ; their shaft shows 

 in its distal portion a number of faint transverse ridges. The superior bristles of this fas- 

 cicle (PI. XXVII, fig. 13), that bear a more slender appendix, have the shaft furnished with 

 obvious transverse ridges, which are very faintly developed in the slender inferior bristles (PI. 

 XXVII, fig. 12). 



In the specimen of Station 81 nearly all the bristles of the neuropodial fascicle are pro- 

 vided with strong transverse ridges on the shaft. The snout-like elongation of the anterior scales 

 of this specimen was not very conspicuous ; for the right anterior elytron, probably having been 

 lost and afterwards regenerated, was covered with some large, irregular lamellae of lime in 

 stead of with the fine regular coating of the remaining part of the body. 



Though undoubtly closely allied to Ps. Jzjietisis, the Siboga-specimens could not be 

 identified with that species, on account of the swollen tip of the tentacle and the tentacular 

 cirri, of the whip-shaped terminal appendix of the dorsal cirrus of the third segment and the 

 different structure of the bristles, their shaft being furnished with prominent, transverse ridges. 



Sub-family Eulepidinae. 



Body rather elongated. Head eyeless ; three antennae, the lateral ones arising quite next 

 to each other in the middle of the front. Scales 12 pairs (15 pairs Mc Intosh), situated on 

 segments 2, 4, 5, 7, 9 . . . . 2 1 and 24. Elytrophores and branchial cirri arising next to the 

 median dorsal line. Stout knee-like bent bristles in the notopodium, commencing in the third 

 segment ; in the neuropodium besides the simple winged bristles a single pectinate bristle 

 superiorly. 



In my opinion the genus Ejilepis cannot be ranged among the Sigalioninae, as done 

 by Grube, neither among the Polynoïnae, as proposed by Augener, büt requires the institution 

 of a new sub-family, as already suggested by Mc Intosh i) and D.^rboux^). Though allied to 

 the Sigalioninae by the branchial character of their dorsal cirri, they are .sufficiently distinguished 

 from them by the absence of compound bristles, as well as by the presence of the stout hook- 

 like setae in the notopodial fascicle.
