382 NOTES oy Australian earthworms 



The girdle comprises three segments, xiv to xvi, and is thick and 

 complete all round, the setae and intersegmental boundaries just 

 visible. 



Setae of the ordinary shape, about '45 mm. long, in eight longi- 

 tudinal rows, not in pairs ; first row on each side ventral, a 

 little to one side of the median line, the second row also ventral, 

 the third lateral, the fourth dorsal ; the first and second rows stand 

 closer to each other than do the third and fourth ; the interval 

 between the third and fourth about equal to that between second 

 and third, and about twice that between the first and second. 



On XVIII a pair of conspicuous somewhat conical elevations mai'ked 

 with several circular groves; on the summit of each a small median 

 papilla (perhaps only the everted terminal portion of the genital 

 duct) on which are the male pores about in line with the second 

 row of setse ; a second and third smaller and less conspicuous 

 papillae, one immediately in front, the other immediately behind 

 the median one, each with a pore through which probably the 

 penial setae are extruded. Oviduct pores two on xiv. Sperma- 

 thecal pores not determinable. Dorsal pores absent. Nephridi- 

 pores not visible. 



Alimentary canal : the buccal mass and pharynx extend through 

 about the first four segments ; in vi and in vii a thin-walled 

 globular portion either or both of which may perhaps be a gizzard ; 

 calciferous glands in segments x-xiii, the last pair very large 

 and conspicuous ; the intestine is quite narrow in the next two 

 segments, while in xvi the large intestine suddenly commences, 

 and continues throughout the rest of the body. 



Genitalia : a single pair of testes only visible in xii, white 

 racemose bodies independent of each other, attached to the 

 posterior face of the mesentery between xi and xii ; an anterior 

 pair possibly overlooked ; ciliated rosettes in x and xi ; vasa 

 deferentia not visible ; prostates a pair of long narrow transversely- 

 disposed bodies in xviii, sometimes folded on themselves, with a 

 rather long much-bent duct coming off from near the inner (lower) 

 end of the gland, gradually increasing in diameter : the two
