that the epithelium of both pouches is in actual contact. This 
minute sac is attached to the Septum x11/xtrr by a strand of 
fibrous tissue (muscular or connective tissue). It is situated on 
the opposite side of the spermatothecal sac to that on which is 
placed the orifice of the duct leading from the oviduct. The 
sac was filled with a few small rounded cells which might be 
immature germinal cells or might, indeed, be any kind of cel- 
lular tissue in an immature state. I have no evidence to bring 
forward that this tissue is really what is left of the ovary, ex- 
cept its position and the fact that it is enclosed in a special sac. 
The egg-sac and the oviduct appear to have the same struc- 
ture and relations as in Polytoreutus ceruleus, The only 
difference that I noted was the absence of any diverticula of the 
oviduct lodging sperm masses such as Michaelsen has figured 
and described in that species. The egg-sacs contained, besides 
ripe ova, germinal cells in various stages of growth. 
In describing the structure of Polytoreutus kilindi- 
nensis I shall have some observations to offer about the de- 
velopment of the different parts of the female reproductive 
organs. 
Polytoreutus kilindinensis, n. sp. (fig. 8). 
The present species was represented by two individuals, both 
of which were collected at Kilindini, on Mombasa Island ; 
they were found, together with another species to be presently 
described, in damp ground where the slops of a household were 
deposited. 
This species cannot be confounded with the next, nor with 
either of the two remaining species of the genus. It is larger 
than the last; the larger of the two individuals measures 
120 mm. in length by a diameter of 5 mm. This specimen 
consisted of 220 segments. The colour, too, is different ; it is 
characterised by the same general coloration, but the violet is 
less deep and less extensive. 
The prostomium is broad, and does not invade in the least 
the buccal segment ; the latter segment has numerous wavy 
lines anteriorly.
