ANNELIDS. I. 



The scales cover the dorsum in its whole breadth; the milky colour of the former is very 

 characteristic, and is present in all the specimens. This is also remarked by Storm: "Color totius 

 corporis et elytrorum lacteus". 



The shape of the foot is the same in all the specimens (fig. 12). Also the shape 

 of the bristles is identical. 



Peculiar to the foot is, that the notopodial branch is somewhat reduced, and 

 that the neuropodial branch is provided with a little flab or tentacle-like 

 prominence which projects somewhat over the acicle. The dorsal cirrus 

 is rather short and beset with short clavate papillae. 



The neuropodial setae are long-shafted, with a short or middle-long 

 endblade, the spines of which are only a little prominent. Under the tip, 

 which is strongly bent, is found a little acute tooth. As a rule this tooth 

 is worn off, (fig. 13 «), but in the new setae it is easily seen, (fig. 13 b). 



The reasons which for the present have made me keep together 

 specifically the specimens from the Trondhjems-Pjord and from the Atlan- 

 ■"4" tic are the following: 



It is known that the species of Storm lives on Oculina; the Atlan- 

 tic specimen which has been taken south of Iceland in a depth of c. 500 fms. 

 originates just from the Oculina-area.

The parapodia and the setae can not be distinguished m the two 

 forms. Last not least, only one specimen is present from the Atlantic; I 

 therefore consider it best to wait for further captures from this locality before forming an opinion con- 

 cerning the question.

 Locality : 



The Ingolf-Exped. St. 67. 6i°3o' N. L. 22°30' W. L. 975 fms. South of Iceland. 



A number of specimens, c. 10 in all, are present from the above named locality. Only half of 

 these are, however, tolerably entire. The rest are represented by laager or smaller fragments. They 

 belong to a form which I have not been able to refer to any known species. It is a typical Harmothoe 

 of rather small size. Almost all the specimens present are alike in this respect. They measure c. 14 mm. 

 in length. The corresponding breadth is, with setae, 6 mm., without setae c. 5 mm. One of the 

 specimens, of which only the foremost half (c. 15 segments) is present, is, however, considerably larger; 

 it measures in length 10 mm. and has a breadth of 9 mm. with setae and c. 7 mm. without setae. 



The cephalic lobe is of the usual Harmothoid type, but it is rather clumsy in shape; the median 

 incision is unusually short and reaches not more than one third of the length of the head; the frontal 

 prominences are small and rounded. No eyes are seen. The median unpaired tentacle has a relatively 

 stout basal joint; the tentacle itself is rather short, the terminal filament long, about the half of the 

 length of the tentacle. The paired tentacles are extraordinarily short; they do not reach the length
