36 Prof. M'Intosli's Notes from tJte 



C. duneri to be Kroyer^s C. infundlbultformis, and that the 

 species held here to be C. infundibuliformis is only a variety 

 of the former (C duneri). Tliis does not modify either the 

 opinions or the figures in this paper, 



Chone duneri has a very wide distribution, ranging from 

 the British seas to Norway, Jan Meyen, Spitzbergen, 

 Greenland, the Gulf of St. Lawrence, and Madeira. A 

 species, wliich closely approaches C. duneri, extends along 

 tlie eastern shores of Scotland, is throAvn by storms on the 

 sands at St. Andrews, is dredged in deep water off Montrose, 

 and occurs in the stomachs of fishes, such as the cod and 

 haddock. It has been termed C.fauveli in the meantime, 

 since the processes at the tips of the branchise form a contrast 

 with the long filiform processes in C. duneri, and its posterior 

 hooks generally show a tooth more above the main fang. 

 Further investigations may clear up certain doubtful points 

 in connection with both forms. Wolleboek^s * view that 

 C. dnneri is a synonym of C. infundibuliformis cannot be 

 corroborated. In the fine volume on the Polychsets procured 

 by the Prince of Monaco, Prof. Fauvel f describes and 

 figures C. duneri as C. infundibuliformis, and it is possible 

 that the rarity of the latter and the abundance of the former 

 in northern waters has led to this misapprehension, which 

 we in Britain equally shared. Prof. Fauvel's figures of the 

 bristles and hooks in his account of the Polychseta from Jan 

 Meyen are excellent. In all probability the species from 

 the area of tlie Clyde % ^s Chone fauveli and not C. infundibuli- 

 formis, which has not hithcito been met with in British 

 waters. The species described by Miss Katherine Bush § as 

 Chone teres appears to be closely allied to the last-mentioned 

 species, especially in the structure of its posterior hooks. 

 Besides the foregoing forms, Chone reayi extends from 

 Shetland to the Channel Islands, and Chone princei occurs 

 in the Gulf of St. Lawrence, Canada. 



Chone fauveli \\, sp. n., the fourteenth species^ is widely 

 distributed in Bi'itain. 



The cephalic plate is surrounded by an ample and con- 

 tinuous collar^ cleft, however, at the dorsal fissure, and it
