ANMU.mS. 1. 





inwards, towards the middle, their lateral contour is convex, while the medial is somewhat concave, 

 rendering the bodies almost renal shaped, with the hilus turned towards each other; the edge is 

 smooth, devoid of incisions. 



The first parapodium, which, as said, is partly coalesced with the cephalic lobe is provided 

 with two tentacular cirri. The largest of the latter, presumably homologous with the paired tentacle 

 in the Polynoids, is about equal in length to the unpaired tentacle; the other is only half that length 

 and conspicuously more slender. First parapodium bears on 

 each side a bundle of long hairy seta;, which are turned forwards 

 and converging. 



The second parapodium is, like the first, turned 

 forwards; it is longer than the first and projects somewhat 

 before this. Its shape is rather high and somewhat 

 compressed; its two branches are partly coalesced; only 

 their distal parts are free and distinct. The parapodium 

 is provided with a lot of long thread-shaped papillae, 

 which mainly are situated on the dorsal side of the 

 parapodium (fig. 22). The ventral cirrus, which in this 

 genus is usually of a considerable length, is here about 

 twice the length of the same organ in the other parapodia. 



The third parapodium is also turned forwards; 

 but not to such a degree as the second, in shape it is 

 transitional between the second and the rest; its distal I 

 half is beset with thread-shaped papilke, but the latter 

 do not reach the length of those in the second parapo- 

 dium, nor are they so numerous. 



The other parapodia are relatively not so high 

 as the foremost described above; their two branches are 

 not coalesced to such a degree as described, and are 

 more separated from one another; the supply with pa- 

 pilla; is much reduced, the latter being not so long 

 and only few. In a parapodium from about the middle 

 of the animal I count in the notopodial branch 3, in 

 the neuropodial 2. The two on the neuropodial branch 

 have been transformed into broad oval flabs. The ventral cirrus is on its dorsal surface irregularly 

 denticulated. 



The acieuke are strong. 



The dorsal setse are very I0110-, exceedingdv delicate and finelv serrated. 



The ventral seta; are, as usual in these species, of different shape; most dorsally is situated a 

 little bundle of a few uncompouud bristles; the latter consist of a straight stem which is rather thick in 

 the proximal half but then tapers quickly to the tip, which is exceedingly delicate. In its distal half
