1542 NOTES ON AUSTRALIAN EARTHWORMS, 
second seta, posteriorly on to xix, and anteriorly being confluent 
with the clitellum ; this presents a transverse furx’ow or depression 
reaching outwards on each side to about the first seta, near the 
extremities of which are the not very conspicuous male pores (the 
details are slightly different in the two specimens from Burrawang). 
Oviduct poi'es rather far apart, in fi’ont and just ventrad of the 
first setse on xiv ; spermathecal pores two pairs, between vii and 
VIII, and VI II and ix, opposite the first setie. 
Nephridiopores conspicuous, three pairs to a segment after the 
first one, on the anterior margins of the segments, or even a little 
way back, opposite or a little dorsad of the first, third, and fourth 
setse on each side. 
Dorsal pores commence between segments iv and v, but the first 
one smaller and less conspicuous. 
Alimentary canal : gizzai’d in v, a white glandular mass over- 
lying both it and the posterior part of the pharynx ; in segments 
x-xvi the alimentary canal presents dilatations in some cases 
looking like rudimentary pouches ; the large intestine begins in 
segment xviii. 
Genitalia : two pairs testes and ciliated rosettes in x and xi ; two 
pairs of racemose vesiculie seminales in xi and xii (in one specimen 
three additional similar but smaller bodies, one in xiil, and a 
pair in xiv) j prostates two pairs, in xviii and xix-xxi, the second 
pair immediately behind and contiguous to the first, the two on 
each side at first sight looking like a single mass ; on lifting them 
however it is at once seen that they are separate, each of them 
having its own duct, but that the two prostatic ducts of each side 
join to form a single genital duct which soon increases in diameter, 
and is bent on itself ; a single vas deferens on each side joining 
the genital ducts at about the junction of the prostatic ducts. 
Ovaries and oviducts as usual ; spermathecee two pairs in viii 
and IX, pouches with distinct thick ducts, from each of which 
come off two short club-shaped cxeca, one on either side.
