(6) C. macedonensis, sp. i\. (Figs. 16, 17, 18, G8). Spirit 

 specimen 8 inches long, one-eighth inch bioad. 



Prostomium not dovetailed into the peiistomiuin, which is 

 ribbed. 



Clitellum distinct, complete and brown coloured in spirit 

 specimens, the rest of the body being bleached. 



. Setae, four couples, regular along the wdjole length. The 

 intervals between the two couples of each side, and between 

 tlie two rows of the outer couple very nearly equal and each 

 more than twice as great as that between the rows of the 

 inner couple. The fourth seta nearly dorsally placed. 



Male pores on papillae on segment 18, at the level of tiie 

 interval between the two inner rows of setas. 



Oviduct pores on segment 14 slightly anterior to and 

 venti-al of, the innermost seta^. 



Spermathecal pores, four in number, on the anterior 

 margins of segments 6-9, slightly ventral to the level of 

 the innermost setae, each on a distinct little papilla. 



Accessory copulator}' structures very well marked. A 

 large tumid patch occupying the median ventral part of 

 segment ] 1, the anterior edge of segment 12 and the 

 posterior of segment 11 ; or this may be divided into two 

 parts, one occupying the anterior ventral part of seg- 

 ment 11 and the posterior juxrt of segment 10 : the othei-, 

 the corresponding parts of segments IJ and 12. 



Beliind the clitellum, tumid ridges are present, the lirst 

 of which occupies the posterior ventral part of segment 17, 

 and anterior of segment 18, and others occupying correspond- 

 ing positions on segments 18 and 19, 19 and 20, 20 and 21, 

 21 and 22. Each has a median linnear groove, corresponding 

 in position to tiie intersegmental groove. 



Dorsal j)ores present, the tir.st between segments 4 and 5. 

 Nephiidial poies not easily seen, l)ut are })laced at the level 

 of the third seta on each side. 



Alimentary canal. Gizzard in segment 5, but not occupy- 

 ing the whole of the segment. Vascular swellings on the 

 oesophaous, but no true calciferous glands. Laig-e ititestine 

 connnencing in segment 18. 



Excretory system. Meganephric. 



Reproductive system. Testes, two jmirs in segments 10 

 and 11. Ciliated rosettes in the same segments. 



Prostates in segment 18, coiled, tubulai-, with distinct 

 coiled duct.
