DR. W. C. M'mXOSH O'S THE ANXELIDS OF 



The tubes are for tlie most part composed of the same quartzose 

 saud as in the examples from the ' Valorous.' The specimens are 

 rather small, the longest tube being 41 millims. in length, and 7 

 millims. in diameter at the anterior end. 



Not uncommon at Iceland and Grreenland. 



Fam. Amphaeetid^. 



Amphicteis Sundevalli, Mahnqren. 



A very fine example (measuring 42 millims. in length and 11 in 

 breadth) from Discovery Bay, in 5 fathoms. 



This agrees with Malmgren's description in having 19 segments 

 with pinnules in the posterior region of the body. The bristles 

 are rather more crenated, and their shafts more distinctly striated 

 than in AmpMcteis Gunneri, Sars ; but the most characteristic 

 difference appears in the hooks, which certainly diverge in a note- 

 worthy degree. 



This species has hitherto been procured only on the eastern 

 shores of Spitzbergen, on a clayey bottom.

Fam. Teeebellid^. 



SciONE LOB ATA, Malmgren. 



From Franklin- Pierce Bay, collected by Mr. W. C. Hart. In 

 tubes composed of coarse chitinous secretion, with adherent sand- 

 particles, Foraminifera, and other minute organisms. 



Not rare at Spitzbergen and Grreenland. 



AxiONiCE FLEXuosA, GrwSe. (Fig. 3.) 



From Floeberg Beach in IO5 fathoms . 

 A single specimen in a somewhat fri- 

 able flattened tube, composed of chi- 

 tinous secretion and quartzose sand. 

 The regular curves of the tubes are 

 remarkable. 



Common on the shores of Spitzber- 

 gen and Greenland.

Everywhere common in the northern seas.
