of the rami 1 1 1 « - whole cirrus to be short. The firsl pair is placed near the mouth and 



ome di the second. lts r.imi are nearl) equal and composed ol five segments 



only. The ent is very long, longer than the other four segments together ;m«l nol 



iposed "i four <t five short and broad segments solden ether. Segments 



. very characteristic péntagonal shape, segment 5 is short, small, quadrangular. 



horter ramus is at the same time ;i little narrower. It can be said t<> have one 



nent more than the longer ramus, as the last segment of those which are soldered together 



form the 1 ment <>l" the longer ramus lias remained free in the shorter one. Each 



irs .1 broad group of long bristles on iis outer surface; the first segment show 



such groups of bristles. The last segment lias the bristles planted close i<> its extremity. 



< >n the inner surface the bristles are less numerous and nol placed so regularly, on tin- outer 



lents they form a row near the extremity. Along the dorsal margin, «ach segment bears 



a long bristle planted slightly above the middle of its length. 



The pedicel of the lirst cirrus is much shorter than that of the other cirri. The filamentary 

 3 si ated beneath the basal articulation of the lirst cirrus; it is long, conical and 

 nted at its extremity. 



The 2 nd cirrus lias ten segments in both rami, the 3 rd 11 in the shorter and 13 in the 



er ramus ; the 4 !h lias [2 and 13 segments, the 5 th and 6 th 1; and 15 — at least these 



the numbers in the specimen 1 investigated more carefully. The pedicels are long, the 



'•nts sli<>rt, slightly longer only than broad. Each segment is protuberant at the anterior 



a little beneath the articulation with the following segment. < >n this protuberance is planted 



a dense brush of bristles; a transverse row of bristles is also inserted on the outer side near 



the extremity of each segment. In the upper segments these bristles have the character of thick 



and claw-like spines. ( )n the inner side the bristles are less strong and also less numerous. 



They form distinct rows only on the upper segments. 



The basal segment of each ramus is in most cirri indistinctly divided into two segments. 

 Thus the o' 1, cirrus miglu as well be said to have 13 and [5 as 12 and 14 segments. 



The caudal appendages are rather long and delicate. In one of the specimens I 

 • teil the one consisted of 8, the other of 10 joints. In length they equal the pedicels <>f 

 the 6 ,h cirrus. the lO-jointed one being slightly longer. The basal segments are short and broad, 

 the middle long and narrow, the upper very narrow, but not so long as the middle ones. The 

 short and thin bristles are planted on the extremity of each segment, the terminal segment 

 being furnished with a tuft of bristles. 



The penis is thick and long, curled together in a curious way, tapering towards the 



extremity. where its end is indistinctly bilobed. The articulations are not very plain, yet the 



as well as the terminal portion eau be said to be ringed, there being an intermediate 



part where the rings can hardly be distinguished. Very long and delicate hairs are scattered 



the surface, forming a somewhat irregular tuft at the extremity in the little furrow between 



the two points or lobes. 



The are small and very numerous. I found a single lamella only. The eggs in 



the specimen I have investigated wen- far advanced in development: most of them contained
