Colour above dark purplish-brown especially in front of the 
girdle, lighter and more reddish at the sides, paler below. Pros- 
tomium divides the buccal ring for a little more than half, the 
latter grooved in the median ventral line. 
Setse at first 20 per segment, just behind the clitellum 24 may 
sometimes be counted, the number increasing in the posterior 
region to about 28. The median ventral interval devoid of setae 
from 2-3 times the width of an ordinary one between two setse ; 
the median dorsal interval narrower, nearly twice an ordinary one. 
Clitellum comprising segments xiv-xvi together with two-thirds 
of XIII and of xvii, complete all round except for a little unmodi- 
fied patch on which are the oviduct pores. 
Male pores on papillae on xviii, about opposite the second setae 
on each side, but being large and slit-like, extending both ways 
beyond these setae. Spermathecal pores two pairs, between vii 
and VIII, and viii and ix, opposite or a little ventrad of the 
third setae. Accessory copulatory structures comprise a pair 
of genital papillae on xvii, and a similar pair on xix, in both 
cases a little ventrad of the papillae carrying the male pores, 
and corresponding with the intervals between the first and 
second setae ; the papillae of each of these two pairs frequently 
connected by an intermediate ridge or swelling — on the anterior 
annulus of xvii and the posterior one of xix ; hence the six 
papillae and their connections come to enclose a basin-shaped 
depression ; sometimes the papillae have one or two pit-like depres- 
sions (apertures ?), and occasionally there is a small papilla on xviii 
between those carrying the male pores : also a pair of swellings 
on X, and another on xi, extending a little beyond the first and 
second setae on each side, and antero - posteriorly across the 
segments, best defined in worms with well-developed girdles and 
then each with a central j)ore-like depression. 
Alimentary canal: only two pairs of calciferous pouches in xi 
and .\ii. 
In other respects like I\ australis.
