Further Descri])tions of Australian Earthworms. 55 



Alimentary canal. Gizzard in segment 5 ; vascular swellings 

 in segments 10-12; no true calciferous glands present; large 

 intestine, commencing in segment 17 ; a white, swollen, twisted 

 part in segment 15. 



Circulatory system. Dorsal vessel single ; hearts in segments 

 6-12. 



Excretory system. Meganephric ; the nephridiopores at the 

 level of the sixth seta from the ventral surface. 



Reproductive system. Two pairs of testes, in segments 10 and 

 11, into which the ciliated rosettes open. 



Spermiducal glands, small, coiled, tubular, in segment 18. 



Sperm sacs, racemose, attached to the posterior wall of segment 

 9 and the anterior of segment 12. 



Ovaries in segment 13, into which the oviducts open. 



Spermathecae, 5 pairs, in segments 5-9, each consisting of a 

 spherical sac with a duct to which a small diverticulum with a 

 swollen end is attached. 



Habitat. Blacks Spui', Victoria. Under logs at an elevation 

 of 2000 feet. 



(4). Diporochaeta euzona, sp. n. (Figs. 70, 71, 72.) Spirit 

 specimens 6 inches long, h inch broad. 



Prostomium scarcely at all dovetailed into the peristomium. 



Clitellum extending over segments 15-19 and the posterior 

 part of segment 14, except in the mid ventral area of segments 

 17-19 and the posterior part of segment 1 6. Accessory copulatory 

 structures in the form of elongate, oval, glandular patches 

 ventrally between segments 17 and 18, 18 and 19, 19 and 20, 20 

 and 21, the patches being united by ridges across the mid ventral 

 line. 



Setae, 18-20 on each side behind the clitellum ; about 15 on 

 each side in front of the clitellum ; distinct dorsal and ventral 

 break, the latter irregular. 



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

 interval between the two ventral setae on each side ; the two 

 papillae united by a median ridge. 



Oviduct pores on segment 14.
