36 Prof. ;M'Intosli's Notes from the 



C. diineri to be Kriiyer's C. infiiiKl'ihul'iformis, and that the 

 species hehl here to be C. infinutiljuli/or/iiis is only a variety 

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

 opinions or the figures in this p;ipcr. 



Clione duneri h:is a very wide (Hstribution, ranging from 

 the British seas to Norway, Jan jMcycn, Spitzbergen, 

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

 species, uliich closely approaches C. duneri., extends along 

 the eastern shores of Scotland, is thrown 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.fauve/i in the meantime, 

 t^ince the processes at the tips of the branchije 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. duneri is a synonym of C. infundibuliformis cannot be 

 c(jrr()l)()rated. In the fine volume on the Polychrets 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 misap|)rehension, which 

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

 bristles and hooks in his account of the Polyclueta from Jan 

 Meyen are excellent. In all probability the species from 

 the area of tlie Clyde % ^s Cbonefauveli and not C. infundihuli- 

 forniis, which has not hitherto been met with in British 

 waters. The species described by ]Miss Katherine Bush § as 

 Clume teres appears to be closel}^ allied to the last-mcutioned 

 species, especially in the structui'e of its posterior hooks. 

 Besides the foregoing forms, Chone reayi extends from 

 Shetland to the Channel Islands, and Chone princei occurs 

 iu the Gulf of St. Lawrence, Canada. 



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

 distributed in Britain, 



The cephalic plate is surrounded by an ample and con- 

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