Genitalia : vesiculse seminales four pairs, in ix-xii, the first two 
pairs adherent to the anterior faces of the mesenteries between 
IX and X, and x and xi ; the second and third pairs to the posterior 
faces of those between x and xi, and xi and xii ; true testes and 
ciliated rosettes two pairs, in x and xi ; prostates in xviii, the 
genital ducts long and nearly straight ; the vasa deferentia not 
■vdsible. Ovaries and oviducts as usual : spsrmathecse five pairs 
of stalked pouches with single stalked cseca, those of each pair 
opening to the exterior by a common aperture under the nerve 
cord, but one of each pair rudimentary, and then the pouch and 
the caecum about the same length, usually alternately on opposite 
sides, at other times so consecutively for two or more segments. 
Last pair of hearts in xii. 
Nephridia ; a pair of long much convoluted tubules in each 
segment except the first. 
Hah. — Narrabri, Coonabarabran, N.S.W. (collected by Mr. T. 
G. Sloane). 
Cryptodrilus fastigatus, n.sp. 
Five spirit specimens 63-89 mm. long, 3-4 mm. broad ; number 
of segments from about 100-140. 
Colour above reddish or purplish tinged with brown, or 
iridescent purplish, lighter below. Prostomiuin completely divides 
the buccal ring. From a little way behind the girdle backwards 
the body tapers steadily. Segments faintly or not noticeably tri- 
annulate. 
Setse of the outer couples much fnrtlier apart than those of the 
inner couples — the outermost row on each side dorsally situated — 
and even than the two couples of each side. 
Clitellum comprises four segments xiv-xvii, compact and com- 
plete all round. 
Genital pores : the whole ventral surface of xviii is tumid, the 
modified surface extending outwards on each side as far aa the
