388 NOTES ON AUSTRALIAN EARTHWORMS, 



Male pores on papillae on xviii, about in line with the 

 2nd or 3rd row of setaj on each side, or with the interval 

 between them. Oviducal pores close together on xiv. Spermathe- 

 cal pores a single pair, between vii and viii, corresponding with 

 the interval between the 3rd and 4th rows of setse on each side. 



Dorsal pores after segment v. 



Accessary copulatory structures comprise ventral thickening on 

 X and XI ; and on some or all of xvi xvii xix and xx there are 

 other structures which are slightly different in the specimens from 

 the three different localities : thus in Springwood specimens the 

 ventral surface of xvii only, or of this and xix, is thickened and 

 marked with a somewhat elliptical fossa extending outwards on 

 each side to the second seta, with a well-marked rim, and some- 

 times a raised central portion, and apparently with a pair of pores. 

 In four Randwick specimens the fossae are on xvii and xx, while 

 on XIX in front of the interval between first and second row of 

 setse there appears to be a pore. In two Manly specimens the 

 fossa is on xvi, while on xvii and xix there are two pairs of small 

 papillfB with pore-like depressions, extending from the first to a 

 little way beyond the second setee. 



Alimentary canal : the gizzard is in v ; four pairs of calciferous 

 pouches in x to xiii with perhaps an additional one in ix ; the 

 large intestine begins in xvi. 



Genitalia : two pairs racemose testes attached to the anterior 

 mesenteries of segments xi and xii ; two pairs ciliated rosettes in 

 X and XI ; the prostates are white compressed bodies, incised 

 superiorly so as to be 3- or 4-lobed, a lobe in each of segments 

 xviil-xx or XXI, the first and second lobes also partially divided by 

 an incision from below, and from the groove so formed emerges 

 the genital duct, the rest of which is bent in horse-shoe fashion, 

 the limbs lying close together, and with the concavity of the bend 

 looking backwards : the ovaries and oviducts have the usual 

 situation and arrangements ; the single pair of spermethecse 

 are in viii, opening anteriorly, each consisting of a large pear- 

 shaped sac with a distinct stalk, and a club-shaped csecum only 

 about half the length of the principal pouch.
