There are considerable tufts of micronephridia by the side of the alimentary 
tube in segments v-ix ; and micronephridia are thinly scattered over the body-wall 
throughout. The remarkable feature is the presence, in addition, of a large nephri- 
dium on each side from segment xvii backwards ; these have however no connection 
with the septa. On opening the specimen and pinning out in the usual way they 
appear as wavy or curled tubes, emerging on each side from under the intestine, and 
extending outwards on the body-wall for a distance equal to half the diameter of the 
intestine or less. Their ventral ends are as a matter of fact only just covered by 
the intestine in this position, as may be seen by drawing the intestine slightly to one 
side. Towards the posterior end of the body these nephridia are smaller though 
still easily visible to the naked eye; they may here be absent on one or both sides, 
or there may be more than one minute tuft. 
The anterior male organs are proandric, with testis-sac and a single pair of semi- 
nal vesicles, as described by Michaelsen. 
In the first batch of specimens, the spermathecal diverticulum was longer than 
in the original account of the species, finger-shaped and of equal thickness throughout, 
not stalked. In the second, while the shape of the diverticulum was more like that 
of the type form of the species, main duct and diverticulum were attached quite 
separately to the body-wall. 
The spines of the penial setae are more numerous than in the original (6-7 rings), 
and do not stand off so much from the shaft; the truncated distal end is narrower. 
Remarks.—Here again the dissection shows that the gizzard is at least not wholly 
in segment vii; the small number of forms which (constantly at any rate) possess 
this peculiarity is thus still further diminished. 
In may be noted that the spermathecal apertures are not here fused in the 
middle line, as in the original. 
Megascolex campester, sp. nov. 
(Plate VIII, figs. 17-18.) 
Horton Plains, Ceylon, 7000 ft.; in jungle paths; Dec., 1913 (S. W. Kemp.) Three specimens. 
External characters —Length 60-74 mm., maximum diameter 4 mm.; colour dark 
slate, only slightly lighter on ventral surface and over first few segments. 
Segments 130. 
Prostomium epilobous 3—3, the posterior process delimited behind by a trans- 
verse groove. 
Dorsal pores begin in groove 5/6, and are present on the clitellum. 
The setal rings are situated on a whiter line round each segment. Ventrally the 
ring is closed, or almost so; dorsally there is a short interval, so that zz=2yz. The 
intersetal distances are rather greater dorsally than elsewhere, and are narrowest 
laterally. The numbers counted were :—v/46, ix/ca.50, xiii/48, xix/50, and in the 
middle of the body ca. 47. 
The clitellum extends over segments xii—xvii=5. It is purple in colour, in one
