206 ' ENDEAVOUR " SCIENTIFIC RESULTS. 



it is 9 mm. across the ventral surface, whence it tapers fore 

 and aft. The width of the 4th chaetigerous is 4 mm., and 

 at the hinder end is 3 mm. It is pale in colour, with little 

 sign of pigmentation ; the caruncle is yellowish, and along 

 the line of union of the crest with the basal lamella is a line 

 of dark purple ; the same colour is present on the cirro- 

 phores of the dorsal cirri and at the base of the branchial 

 cirri. 



The cha?ta% which are said to be pale green in the type, 

 are here colourless, glassy, though in a less well preserved 

 specimen they are pale yellow. 



This suggested that perhaps I had Haswell's N. flavus 1 

 before me, and the almost total absence of serrations on the 

 chaetse inclined me to that view, but he states that amongst 

 the dorsal bristles some are simple, while in the genus 

 typically all are forked. I find no simple ones. 



Potts 2 has recently tabulated the species according to the 

 presence or absence of serrations. In the present case I can 

 only find serrations on the ventral chsetse of the anterior 

 segments, and then they are so ill-defined that under a low 

 power (Leitz, Oc. 3, Obj. 3) they are not recognisable. 

 Under a higher combination, however, there are seen, as 

 M'lntosh figures them, as minute step-like interruptions in 

 the margin of the larger prong. 



Except for this small difference, my specimens agree with 

 M'Intosh's so closely that I do not feel justified in making 

 a new one.

This worm I have taken on several occasions on the coasts 

 of New Zealand, though I do not think that it has been 

 recorded since Quatrefages wrote his brief account of it. 

 Its leading feature is the absence of bifurcation and of ser- 

 rations on the chaeta?.
