NOTES ON AUSTRALIAN EARTHWORMS. 
Rah . — Sydney (common in the Hon. W. Macleay’s garden at 
Elizabeth Bay). 
This species is allied to P. australis^ but differs in respect of the 
papillae on which the male pores are situated not mammillary, in 
having accessory genital papillae and ridges on xvii and xix, and 
swellings on x and xi, in having fewer setae in the posterior region, 
and the spermathecal pores more ventrally situated ; individuals 
also are smaller, the body comprising fewer segments ; while there 
is a tendency for much both of xiii and xvii to be included in the 
girdle. I have recently obtained some large and very fine 
examples of P. australis which have the ventral surface of xvii 
more or less tumid, with a depression opposite and in front of 
the papillae carrying the male pores.
