dark reddish-brown and black band. In the preserved condition 
the ground colour was still whitish, and the bands were of a 
dark purple; in width the bands were the equivalent of more than 
the middle third of each segment; they were less distinct ventrally, 
especially behind the genital region. The setae were indicated 
by whitish points in the dark rings. Segments 30, but the speci- 
men had previously been mutilated at the hinder end. 
Prostomium epilobous 4, with curved posterior border. 
The dorsal pores begin from furrow 4/5. 
The setae are in unbroken rings; I was unable to count them, 
but found them set closer together ventrally than dorsally. 
No clitellum was visible, nor was it, later, distinguishable in 
sections. 
The male genital area, on segment xvili, is a clean-cut oval 
with its longer axis transverse, which occupies the whole length of 
the segment. The apertures appear as black points on considerable 
rounded papillae which project upwards slightly from the floor of 
the oval depression; these papillae are almost confluent, being 
divided from each other only by a slight longitudinal depression in 
the middle line. The depth of the oval is therefore greatest in two 
transverse lines within its anterior and posterior boundaries respec- 
tively (fig. 17). 
The female aperture was not distinguishable. 
Spermathecal apertures were made out near the middle line 
as minute white points in the furrows from 5/6 to 8/9; but sections 
subsequently showed them to be seven pairs in all, beginning in 2/3. 
Internal Anatomy.—This was investigated by means of sections. 
The pigment of the bodywall appears as an opaque darkish 
green in the stained sections ; it is disposed as a ring in each seg- 
ment in the deeper portion of the circular muscular coat, and alto- 
gether superficial to the longitudinal fibres. 
The first septum is 4/5; that and the following one are thin ; 
the rest are all of the same thickness, none being specially thick- 
ened. 
The septal gland cells extend back into segment vil. 
There is no trace of a gizzard. The oesophagus extends from 
the pharynx to the intestine as a straight, almost perfectly cylin- 
drical tube, without segmental swellings, widening very gently 
however in xii, xiii, and xiv before suddenly dilating to form the 
intestine in segment xv. ‘The internal surface of the oesophagus 
is somewhat more papillose in xiv than elsewhere, without however 
forming lamelliform folds or calcareous glands. 
The last heart is in xii. 
The excretory system is meganephridial. 
Testes and funnels are free in segments x and xi, enveloped 
in masses of developing spermatozoa which fill up the whole of the 
two segments. 
The vesiculae seminales, in xii, attached to the posterior face 
of septum 11/12, are paired, and come near but do not touch each 
other in the middorsal line.
