NOTES ON AUSTRALIAN EARTHWORMS, 
RA, 
Like the pi'eceding one this is another species belonging to the 
group of which C. mediterreus is the type. The grooving of the 
prostomium and first two segments, the additional pair of sperma- 
thecal pores, as well as its general appearance are among the 
external characters which serve to distinguish it. 
Cryptodrilus manifestos, n.sp. 
Seven i-ather contracted spirit specimens from 5-7 cm, long, 
4 5-7 mm. broad ; number of segments about 150-190. 
Colour pallid or flesh-coloured. Prostomium divides the buccal 
ring completely. Segments usually more or less completely tri- 
annulate, frequently the anterior annular groove the more distinct; 
segments widest antero-posteviorly and most conspicuous in front 
of the girdle especially from segments iv or v to ix-xi. 
Sette in eight longitudinal rows of which on each side two are 
ventral, one lateral and one dor.sal : the setae of the outer couples 
further apart than those of the inner ones, and nearly as far as the 
two couples of each side. On segments XIII-x^'II the setae of the 
second row on each side stand successively a trifle closer to the 
corresponding setae of the first row ; on xviii the setae of the inner 
couples not visible ; from xix to xxii or thereabouts the second 
rows again diverge. 
Clitellum comprising four segments, xiv-xvii, complete all round. 
Male poi'es rather close together in correspondence with the 
approximated spermathecal pores, separated by a slight depression 
in the median line, on .small papillae on xviii, just ventrad of the 
innermost setae. Oviduct pores in front and just ventrad of the 
first setae ; spermathecal pores four pairs, on the anterior margins 
of segments vi-ix, the pores of each pair on either side of the 
median line remarkably close together. On xvii, xix, and on the 
next three or four segments there are usually accessory copulatory 
structures — papillae or depressions corresponding with the intervals 
between the setae of the inner couples, those of some of the 
anterior pairs connected by a transverse depression.
