Description of Victorian Earthworms. 145 



Clitellum well marked, but incomplete veiitrally, especially 

 at the anterior end. 



Setse somewhat difficult to see. In four couples, the outer 

 couple being placed laterally, and having its two rows 

 slightly farther apart than those of the inner couple. The setae 

 become irregular in the ui>per two rows in the clitellar region, 

 the innermost row of each side being i-egular along the whole 

 length. 



Male pores on two papillse on segment 18, at the level of 

 the innermost .set?e. 



Oviduct pores on segment 14. 



Sperinathecal pores, five in number ; intersegmental ; the 

 first between segments 4 and 5. 



Dorsal pores ])resent, the first between segments 3 and 4. 



Alimentary canal. Gizzard occupying half of segments 

 5 and 6. No true calciferous glands, but vascular swellings 

 present in segments 8-14. Large intestine commences in 

 segment 19. 



Circulatory system. Dorsal vessel double in each segment 

 as far forward as the fifth segment. The last heart is in 

 segment 1 3, and a lateral vessel is present on each side in 

 segments 5-11, and a supra-intestinal in segments 8-14. 



Excretory system. Plectonephric. The little nephridial 

 tufts are very minute, but for the ]30sterior third of the body, 

 large paired nephridia are present ventrally, with internal 

 funnels. 



Reproductive system. Testes, two pairs in segments 10 

 and 11, with rosettes opening into the same segments. 



Prostates flattened with the surface mammillated in 

 segment 18. Sj)erm sacs, a pair of grape-like structures on 

 the anterior wall of segment 1 4, and of sac-like structures 

 on the posterior wall of segment 9. 



Ovaries in segment 13, into which the oviducts also 

 open. 



SpermathectE. Five pairs in segments 5-9. Each con- 

 sisting of a sac with a diverticulum about half the length of 

 the sac. The spermathecse are small in relation to the size 

 of the body. 



Habitat. Croajingolong. Collected during an expedition 

 of the Field Naturalists' Club of Victoria.
