usually intersegmental taking in one annulus of xviii and one of the 

 segment in front or behind, or confined only to the annuli of xviii. 

 Oviduct pores two, rather close together, in front and ventrad of 

 the innermost setse on xiv. Spermathecal pores two pairs between 

 VII and VIII, and viii and ix, in line with or just dorsad of the 

 setse of the second row. 



Nephridiopores not visible in any of the specimens. Dorsal 

 pores not determinable on the clitellum nor in front of it, the first 

 visible one between xviii and xix. 



Alimentary canal : gizzard in v ; calciferous dilatations possibly 

 in about segments ix-xiii, but no pairs of pouches; the large 

 intestine begins in xvi. 



Genitalia : one pair of testes and one pair of ciliated rosettes in 

 XI ; one pair of vesiculse seminales in xii ; a pair of long narrow 

 linear folded prostates partly in xviii and partly in xix, anteriorly 

 giving ofi" the genital ducts which are fairly long and straight, a 

 single vas deferens on each side joining the prostatic duct close to 

 the gland ; behind each genital duct is a pair of delicate sacs each 

 containing a couple of curved tapering penial setse. Ovaries and 

 oviducts as usual ; spermathecse two pairs in viii and ix, pouches 

 with remarkably long ducts each with a pair of (in one case three) 

 simple club-shaped caeca, one on either side of the duct near its 

 exit. 



Nephridia : delicate tubules, a pair to a segment. 



Last pair of hearts in xii. 



Hah. — Grafton, Clarence Eiver, N.S.W. (received from the Rev. 

 A. Swift). 



A distinct species whose affinities are not very clear at present. 

 I received a considerable number of worms from Mr. Swift, but 

 with the exception of the above and half a dozen specimens of 

 perichsete worms, the rest were simply the ubiquitous Allolohopliora 

 turgida, for which Grafton is the most northerly locality in N.S.W. 

 from which I have yet seen specimens.
