NOTES ON AUSTRALIAN EARTHWORMS, 
Spermathecal pores two pairs, between segments vii and viii, and 
VIII and IX, opposite the first setse. 
Dorsal pores commence after about xii, the first one or two not 
always distinctly visible. 
Nephridiopores not visible. 
In having six pairs of calciferous pouches in viii-xiii, as in 
other respects, this species agrees with P. Coxii. Points of diflfer- 
ence are that the two pairs of vesiculae seminales are in ix and 
XII, instead of consecutive segments ; the spermathecae are long 
pyriform pouches each with a single distinct club-shaped caecum ; 
the prostates ai’e smaller, extending through only about three 
segments, and the last pair of hearts is in xii.

This, and the species next to be described, belong to the same 
section of the genus as F. Coxii, characterized by a marked differ- 
ence in the number of setae on the anterior and posterior setigerous 
segments, caused by a tendency in the former to a reduction in 
the number ; also by the pallid colour of the body, and by the 
large number of pairs of calciferous pouches. [In P. Coxii the 
setae ai-e not at all conspicuous on the first few setigerous seg- 
ments, especially on the first two, i.e., segments ii and iii ; but after 
re-examining a number of specimens I find that these two seg- 
ments have usually each 8 setae — in one specimen on iii there 
were 8 on one side and 6 on the other — after which the next few 
segments have 12, or here and there, as far back as xiii, 14 or 16 ; 
still further back the setae become more numerous and the seti- 
gerous ridges more conspicuous, until posteriorly the number 
increases to about 30 with many gaps in the half-circles, but 
occasionally when these are more complete as many as about 50 
may be counted ; the two innermost (ventral) rows are straight 
throughout, and are the only regular ones. The body is also 
much more robust, and the genital papillae are not inter- 
segmental but are chiefly on the anterior annuli except when 
there is more than one on a segment]. The three species are
