purplish ; from experience in other cases I regard this as indicative 

 of a waxing or a waning clitellum. If so then this species like 

 P. canaliculata is intraclitellian. 



Male pores on two large papillae, the outer (dorsal) margin of 

 each extending to about the sixth set^e, their inner margins con- 

 nected bj an intermediate somewhat swollen portion ; these struc- 

 tures occupy the entire ventral surface of xviii within the limits 

 mentioned, obscuring the setse if these are present, and they bulge 

 a little antero-posteriorly ; the pores themselves are about in the 

 line of the second row of setae. Oviduct pores two, in front and a 

 little ventrad of the innermost setee on xiv; spermathecal pores four 

 pairs in the intervals between segments iv-viii, about opposite or 

 a little ventrad of the second setse ; (the first pair a segment in 

 advance of the usual arrangement). 



Dorsal pores commence after segment v. Nephridiopores a pair 

 to a segment after the first, just behind the anterior margins, 

 forming a single irregularly sinuous series on each side, the pores 

 varying in position from opposite the fourth or fifth setae to dorsad 

 of any visible setse, and not very far from the median dorsal line. 



Hab. — Mt. Bellenden-Ker, N.E. Queensland (received from 

 Mr. Henry Tryon). 



This distinct species belongs to the same group as P. canali- 

 culata, FL, from the same district. At present I refrain from 

 dissecting the single specimen available. 



From time to time I have received or collected a number of 

 small perichsete worms from various localities in N.S.W., which 

 while diflering for the most part a good deal in size or general 

 appearance from the typical forms of the species to which as 

 varieties, at any rate provisionally, I now propose to refer them, yet 

 present no sufiiciently satisfactory or important points of differ- 

 ence entitling any of them to rank as independent species. From 

 the small size and stunted growth, or not good state of preserva- 

 tion of some of them, together with the difficulty in determining
