A single rather large fragment is present from the named locality, representing the foremost 

 fourteen seta>carrying segments. It is a quite typical specimen in all respects; the cephalic lobe, the 

 proboscis protruded, and the setaj agree well with the description and figures of Sars. Only the 

 longitudinal fold on the dorsal side of the palps is not prominent. 



This species is essentially known from the coast of Nor wax, but seems to be scarce everywhere. 

 It has been taken at Drdbak in 40— 50 fm. by M. Sars, at Lofoten in 150^200 fm. by G. 0. Sars 

 and in the Trondhjemsfjord, 120 fm. by Storm. According to Me. Intosh it has been taken near 

 Donegal and at different places off the Irish coast. The Porcupine-Exped. has taken it in 370—420 fms. 

 According to Verril it has also been found at the coast of America. Tauber indicates that two 

 specimens have been taken by Collin in Oresund at Hellelxek; it is impossible now to elucidate the 

 real facts of this case; at any rate the two specimens in mention are not present in the museum 

 in Copenhagen.

The material available consists only of a fragment representing the foremost 28 segments of 

 the body save the cephalic lobe and the buccal segment. It measures in length 31 mm.; the width 

 comes to 15 mm.; without seta; only 10 mm. 



The cephalic .lobe (PI. I, fig. 7) is somewhat longer than broad, the anterior incision is rather 

 broad and reaches nearly to the middle of the head; the two lateral halves of the latter end 011 each 

 side in a short, conical, papilliform prominence; these two prominences are not quite parallel but 

 diverge a little. There are no eyes. The palps are long, rather thick and quite smooth; they are 

 thickest at their base and taper gradually towards the apex; they are devoid of terminal filament. 

 The unpaired antenna measures about \j s of the length of the palps; it is. like the paired antennae 

 and the tentacular cirri, beset with a few small clavate papilla. 



Only a few scales are present; they are soft and gelatinous, thin and feebly translucent of a 

 whitish hue; their shape is broadly reniform with the elytrophore situated near hilus. Along the
