NOTES ON AUSTRALIAN EARTHWORMS, 
Prostates are a pair of long linear bodies coiled and folded into 
a mass, one extremity giving off the genital duct. Each of the 
spermathecEe, of which there are two pairs, has a single rather 
rudimentary ciecum. 
Ilab. — Braidwood, N.S.W. (sent by Mrs. Caird). 
This is a distinct species, though from the few unsatisfactory 
specimens so far to hand the above description characterises it but 
imperfectly. It is allied to C. fastigalus in some I’espects, these two 
species at present standing alone in having three pairs of nephri- 
diopores to a segment, and the prostomium completely dividing the 
buccal ring. They are readily distinguishalde from one another by 
the difference in (1) colour, (2) the situation of the middle pair of 
ne])hridiopores, (3) the characters of the prostates, and (4) the 
caeca of the spermatheca?. The dorsal pores commence further 
forward in C. fastigatus. 
Cryptodrilus mediocris, n.sp. 
Ten (spirit) specimens are from 32-65 mm. long, and ‘2-3’5 mm. 
broad; number of segments from about 114-125. 
Colour : body pallid but tinged with brown especially just 
anteriorly. Prostomium does not divide the buccal ring at all, 
but looks like a forward prolongation of it ; the second segment 
not so distinctly separated from the first one as usual. 
Setai in eight longitudinal rows, those of the outer couples 
further apart. 
Clitellum comprising four complete segments, xiv-xvil, together 
with as much as half or two-thirds of xiii ; complete all round, 
but the divisions between the segments on the ventral surface not 
entirely effaced. 
Male pores not conspicuous, on xvili, about in line with or just 
dorsad of the first setje, near the posterior edge of the pits with 
tumid margins usually present on this segment. Oviduct pores 
relatively close together on xiv ; spermathecal pores two pairs, on
