villosa, H. Ratlike, likewise occurs, and an example about 

 § of an inch in length is so free from sand that the papillae 

 are clearly visible on the pale yellowish-brown surface. 

 This species shows considerable variety in external appear- 

 ance, but the bristles and crotchets remain distinctive. The 

 Trophonia arctica of Hansen does not appear to differ 

 materially from this form. 



The only example of the Chaetopteridae is the widely 

 distributed Spioclwetopterus typicus of Sars, tubes of which 

 occur in 96 fathoms in Trinity Bay, Saguenay County, as 

 well as a fragmentary form at Station 4, 1872. 



7. On the same Families dredged in Norwegian Waters 

 and in Finmark by Canon Norman. 



The rich collections of Canon Norman from northern 

 waters include examples of Stylarioides plumosa, O. F. M., 

 off Bergen, Christiania, and other localities, as well as from 

 Finmark, but they are comparatively small in contrast with 

 the British specimens, the finest of which occur between 

 tide-marks. An abundant northern form is Stylarioides 

 glauca, Malmgren, and one still more characteristic of 

 Norwegian waters is Stylarioides Jlabellata, Sars, which is 

 found in great beauty. From Finmark come Brada villosa, 

 11. Rathke, Brada granulata, Malmgren, and another which 

 differs from both. Average examples of Flabelligera ajfitus, 

 iSars, are not uncommon in the Norwegian Fjords. 



A species, Stylarioides hirsuta, Hansen, dredged at 

 Stations 74 and 84 in Finmark in 1890, appears to correspond 

 closely, so far as can be made out from the brief description 

 and figures, with Trophonia hirsuta of Hansen *. The 

 incomplete body is about half an inch in length, somewhat 

 clavate in outline, and with 17 bristled segments. The 

 colour is dull yellowish or ochre, with the clavate papillae 

 of the first two segments of a reddish brown and forming- 

 two rings, whilst a little of the same pigment occurs on 

 the next six or seven feet. The dorsal surface (PI. XII. 

 fig. 2) is clothed with remarkably long papillae, so as to be 

 woolly, especially posteriorly. On the ventral surface the 

 papillae are comparatively short, especially on the dilated 

 anterior region. About 17 bristled segments are present. 

 The first segment is marked by an ellipse of the reddish- 

 brown papillae and certain much longer pale papillae, as 

 Well as by the somewhat slender and short tufts of golden
