except in the clitellar region : behind this they appear to be 

 somewhat irregular. 



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

 interval between the setae of the ventral pair. 



Oviduct pores on segment 14. 



Spermathecal pores, two pairs, intersegmental between segments 

 7 and 8, 8 and 9, at the level of the ventralmost setae. 



Dorsal pores present, the first between segments 5 and 6. 



Alimentary canal. Gizzard in segment 5. In the segment in 

 front of this the walls are dilated but not thickened. Vascular 

 swellings in segments 14 and 15, a pair of calciferous gland in 

 segment 16. Large intestine, commencing in segment 19. 



Circulatory system. Dorsal vessel single. Hearts in segments 

 6-13. Two swollen lateral branches pass ofi" on each side to the 

 walls of the calciferous gland. 



Excretory system. Plectonephric. 



Reproductive system. Testes, two pairs, in segments 10 and 

 11 into which the rosettes open. 



Spermiducal glands, small, lobate, in segment 18. 



Sperm sacs, attached to the anterior wall of segment 12. 



Ovaries in segment 13, into which the oviducts open. 



Spermathecae, two pairs, each consisting of a somewhat 

 spherical sac with a short, rounded diverticulum. 



Habitat. Near Maryborough, Queensland. (Collected by. Mr. 

 R. A. O'Brien). 



(3). Cryptodrilus cooraniensis, sp. n. (Figs. 34, 35, 36). 

 Spirit specimens 2| to 3 inches in length, ^ inch broad. 

 Number of segments about 142. 



Prostomium completely dovetailed into the peristomtum. 



Clitellum well marked, extending over segments 14-16. 

 Accessory copulatory structures in the form of glandular patches 

 ventrally on segments 17 and 18 ; one pair at the level of the 

 interval between the ventral pair of setae on segment 17, and 

 three median patches on segments 17, 18, and 19. 



Setae quite regular along the whole length of the body : the 

 ventral pair on each side near to the mid line and close together ;
