Some fragments are present, unfortunately in a rather bad condition, so that it is with some 

 hesitation that I venture to refer them to Storm's species. No scales are present, but the bristles 

 resemble very much those of a specimen of H. violacea which Storm has presented to our museum. 



In his paper on the Annulata polychseta of Norway, Bidenkap mentions this species as 

 identic with M aim gr en's Lcenilla glabra and he refers to his paper: "Undersogelser over Annulata 

 polvchseta" in Archiv for Mathematik og Naturvidenskab 1894, where he deals with a single specimen 

 taken at Brommelhuk in 60—80 fans, by the author himself. He remarks that this specimen agrees 

 in all respects with the description of Malmgren of L. glabra, except the position of the eyes, and he 

 adds, that the small chitinous bodies on the scales, the structure of the bristles, the relative length of 

 the appendages of the cephalic lobe & c. are entirely typical. I shall hereto only remark that if the 

 specimen here mentioned by Bidenkap is identic with Mai mgr en's L. glabra, it cannot be referred 

 to Storm's H. violacea. By the kindnes of Professor The el I have borrowed from the "Riksmuseum" 

 in Stockholm M aim gr en's specimen of H. glabra, and the first glance proved the two forms to be 

 different to such a degree that no confounding is possible. Without any discussion of the problem 

 Bidenkap here unites two well defined species, and only succeeds in increasing the previously great 

 confusion in the systematizing of this group.

The species has been taken by the investigation-steamer '-Trior"; a great number of fragments 

 are present, all in a rather bad condition. All appendages are lacking, even the parapodia are in several 

 segments torn off or partly torn off. As far as it is possible to judge -- not a single entire specimen 

 is found and all the fragments represent front parts — the size of the animal has been about one and 

 a half centimeter. The breadth, with setae, makes about 7 mm. A few fragments, however, are some- 

 what smaller. A single fragment representing about the foremost half of a specimen is found in a 

 somewhat better state of preservation than the rest. A deep brown-violet colour remains on the dor- 

 sum, and even a few scales were found in situ. The following description refers mainly to this specimen. 



The cephalic lobe is of the ordinary polynoid shape (PI. I, fig. 10). The sagittal incision reaches 

 about to the middle. The frontal prominences are rather conspicuous and terminate in an acute tip.
