in 5-20 fathoms in 1875. The collar is deep all round like 

 that of C. reayi, but the single example does not show the 

 pedicle for the branchiae (which are absent) on a level with 

 the margin as in that species. Eight bristled segments 

 occur anteriorly, the dorsal tufts having moderately elon- 

 gated tapering tips with distinct, though rather narrow, 

 wings and with a slight curve. The lower bristles are 

 spatulate, with stout shafts which remain nearly cylindrical 

 to the wings, then slightly diminish to a blunt tip, and the 

 web is somewhat short with a smoothly rounded end. The 

 bristles of the second region have shafts which are con- 

 stricted distally, the tip thereafter making an angle with 

 the shaft, the winged tip then tapering to a fine point. 

 The bristles are of moderate length and rather stout, one in 

 each tuft especially surpassing the others in size. They be- 

 come longer and more slender toward the tail. The anterior 

 hooks have stout curved shafts, which increase from the 

 root or base to the shoulder and are striated and yellowish 

 by transmitted light. The neck is translucent, stout, and 

 the main fang, which leaves the neck at an obtuse angle, is 

 short and strong, and has about four distinct teeth above it, 

 the crown posteriorly projecting a little. The posterior 

 hooks (PI. III. fig. 9) approach those of Chone fauveli, but 

 show only three teeth above the main fang instead of four in 

 the British form, the base is less massive and the striation 

 differs, yet there is a close resemblance, which is interesting 

 in forms so divergent in habitat. As mentioned, this is the 

 type of hook Prof. Fauvel associated with Chone infundibuli- 

 for mis, Kroyer, but it is essentially different, as are likewise 

 the bristles. 



4. On the Sabellidse dredged by Canon A. M. Norman 

 off Norway and F'mmark. 



Besides Sabella nordenskioldi and Chone normani described 

 subsequently, Sabella penicillus, L., was obtained at several 

 stations along with Potamilla reniformis, Kr., Amphicora 

 fabricii, O. F. M., and Chone duneri, Mgrn. 



Sabella nordenskioldi *, sp. n. 



A Sabellid which at first sight resembled Sabella 

 crassicornis from its finely coloured branchiae and the 

 disposition of the collar, and nearly 2 inches long, was 

 dredged by Canon Norman off Finmark. The collar
