Of spermathecae there is a pair in each of segments vn, vm, and 

 ix ; opening anteriorly, the apertures being between vi and vn r 

 vil and vm, and vm and ix, and nearly in a line with the second 

 row of setae on each side ; each spermatheca is pear-shaped and has 

 a long caecum as in P. australis. 



On the ventral portion of segment ix is a raised elliptical or 

 more or less rectangular area occupying the whole width of the 

 segment and extending laterally as far as the second row of setse 

 on each side, while on it is a pair of small pits or possibly pores, 

 one on each side of and rather close to the median line. The 

 ventral portion of x is similarly modified, but here the thickened 

 area extends further out on each side (to the 3rd row of setae), and 

 is divided by a median groove into two nearly square or oblong 

 areas, with a depression or pit in the middle of each. 



On xvii and occupying the interval devoid of setae is a pair of 

 small copulatory papillae with a pit or pore on each, rather close 

 together and with their inner margins joined by a short transverse 

 ridge, so as to form a somewhat dumb-bell-shaped area. On xviii 

 ventrad of each papilla carrying a male pore is a second but smaller 

 one, so that this segment carries four papillae. On xix the arrange- 

 ment is similar to that on xvii but with the two papillae a little 

 further apart. 



The prostates are very much incised or lobulated, and the short 

 thick ducts run almost perpendicularly, and are joined by the vasa 

 deferentia close to the glands. 



The other organs do not differ materiallv from what has been 

 described in P. australis.

The worms of this species live together with the four other 

 species previously described from the same locality, and were 

 collected at the same time as those mentioned, but thinking they 

 were young specimens of P. australis I did not pay particular- 

 attention to them.
