The clitellum occupies four segments — 14 to 17 inclusive, 
and a portion of segment 13. In my earlier paper on the 
genus (2) an exactly similar condition of the clitellum is noted. 
Dorsal pores are present on all segments after, and including, 
the tenth. The pores of the spermathecse are very con- 
spicuous between segments 7 and 8 ; they correspond to the 
interval between the dorsal and ventral pairs of setae (fig. 7, 
c-P •)• 
The male generative orifices are upon segment 17, and 
correspond to the ventral pair of setae. 
Between segments 19 — 20, 20 — 21, and occupying the 
whole of the space corresponding to the interval between the 
two ventral pairs of setae, is a single large papilla (see fig. 3). 
The arrangement of the genital papillae in this species is there- 
fore apparently different from that which characterises T. 
orientalis. The number and position of the papilla agrees 
with Pontodrilus (Perrier (16), p. 177, pi. xiii, fig. 1, b.') } 
with which genus, however, the present has but few other 
points in common. 
Internal Anatomy. 
Body Cavity. — Under this head I refer to the condition of 
the intersegmental septa in the anterior region of the body. 
As in other Earthworms this species is seen to have a 
number of these septa thickened and hypertrophied. The first 
of these septa lies between the fourth and fifth segments; the 
next in the succeeding segment. Tlie two following seg- 
ments, which are occupied by the gizzard, are not divided by 
a mesentery at all unless the muscular bands which bind 
the anterior region of the gizzard to the body wall can be 
regarded as the remains of the septum dividing segment 6 
from 7. Farther back are three thickened septa which lie 
between segments 8, 9, and 10. These latter are remarkable 
from the fact that they do not divide the body cavity into 
segments precisely equivalent to those indicated by the external 
characters. 
The first of these mesenteries corresponds to the first
