ANNELIDS. I. 



Several among these are not more curved than Malmgren's figure indicates. < >f course it is awkward 

 to choose one of the few rather straight dorsal setae when the greater part are far more curved. Small 

 himself draws one of the more curved dorsal setae, and his figure, especially concerning the small 

 spines on the bristles, is more correct than those of Malmgren; in so far Small's figures eke out that 

 of Malmgren, but, according to my opinion it had been more opportune if Small had given one figure 

 more, namely of one of the most curved dorsal bristles which are so strongly curved that the two 

 halves of the bristle, which are bent towards each other, form a right angle. Dorsal setae of such a 

 shape, so strongly curved are found in only very few species. They are found in the genus Gatty- 

 ana, specially in (i. cirrosa. As also the shape ot the ventral setae of H. villosa call to mind those 

 of the genus Gattyana, it can scarcely be surprising that I looked very thoroughly for threadshaped 

 dorsal bristles in H. villosa; if such had been present I would without hesitation have proposed to 

 refer H. villosa to the genus Gattyana; now it max admit of doubt if it is to be done or not. That 

 the species in mention is closely related to the genus Gattyana is, according to my opinion, beyond 

 doubt; of traits of character approximate to Gattyana I shall name: the mentioned, strongly bent 

 dorsal seta;; the shape of the ventral seta;, especially the shape of the endblade; further the dense 

 supply of papilla; on the scales, partly on the cirri too, specially the proximal half of the dorsal 

 cirri is densely beset with papillae. Finally, last not least, the small bodies on the scales show ten- 

 dency to ramification of the apex, a case which is well known in the genus Gattyana. I can add that 

 the segmental papillae are rather prominent, about of the same length as the ventral cirri. All in all 

 I find it a matter of taste whether it is to be referred to the genus Harmothoe or Gattvana; it repre- 

 sents a real transitional form between the two genera in mention ; perhaps it really is closer related 

 to Gattyana than to Harmothoe, 



As regards the geographical distribution it is possible to state that //. villosa is widely spread 

 over the Norwegian sea and that it enters the Atlantic. In Greenland it is found on the east as well 

 as on the west coast. It seems to be common in the deeper regions of the Greenland fjords.

Locality : 



Ingolf-Exped. St. 18. 6i c 44' N. L. 30°2o,' W. L. 1 135 fm. 



The present species has first been captured by the Challenger, East of Prince Edward's island, 

 S. W. of Africa in a depth of 1375 fm. Further, Augener gives an account of a specimen from the West 

 Indies from a depth of 291 fm., and finally the species has been taken by the Valdivia Expedition 

 at the coast of Somali in 1242 fms. When we hereto add the locality from the Ingolf-Expedition from 

 the northern part of the Atlantic we can scarcely doubt that we here have a deep-sea form with a 

 very large geographical range.
