238 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Poli/rhaeta. 



fading to white further back ; the tentacles and cirri are white. The hinder 

 segments are longer than those in front, (iwing to the contained eggs, which distend 

 the body. 



Length, 15 mm. ; breadth, 1 mm. ; with 8.5 segments. 



Ehlers states that the dorsal cirri are somewhat spindle-shaped in the individuals 

 examined by him, owing to 2 or 3 joints in the middle being wider than the rest. 

 I do not detect this in the specimen at my disposal ; the joints are widest at the 

 base of the cirri, and the organ tapers slightly, and is composed of some 13-15 

 annuli. 



In the parapodia the 6 or 8 chaetae are all alike in form, bnt the appendix of 

 the upper ones is twice the length of that of the lower ones, and there is a gradual 

 decrease in its length from above downwards ; this is true not only for the posterior 

 but for the anterior feet. 



In view of Ehlers' remarks on the variability of the length of the appendix in 

 different specimens from Christchurch and from Chatham Island and from the Cape 

 of Good Hope this seems worthy of mention. 



Locality. — Campbell Island : Perseverance Harbour ; (T. J. Parker, 1895). 

 Antipodes Island ; (L. Cockayne, 1903). 



Distribution. — New Zealand and Chatham Island ; Caf)e of Good Hope.

 A single specimen of a large Nereid was forwarded to me by Professor H. B. 

 Kirk, who collected it on the shore of Perseverance Harbour, where it occupied 

 " a tube of sand on the underside of a stone at low-water mark." The colour is 

 thus noted on the label : " Dorsal vessel deep red ; notopodia and neurojiodia pink ; 

 general effect red, with iridescence in which purple predominates." 



The animal is preserved in formol, and now is of a dull fleshy brown ; the 

 anterior end has a greenish tint, and the median line is dark. There are dark-grey- 

 coloured glands at the bases of the parapodia, which become much pronounced 

 towards the hinder end of the worm.
