1g16. | J. StePHENSON : Indian Oligochaeta. 
The prostates, compact in form, are confined to xviii. The 
duct is stout and very muscular, and passes from the middle of the 
gland downwards and then inwards. 
The ovaries and their funnels have the usual position. 
The spermathecae are seven pairs, the first opening in furrow 
2/3 and the last in 8/9. The ampulla is ovoid, the first of the 
series is ‘2 mm. long, and some subsequent ones ‘25 mm. The 
duct is short and comparatively stout,—half the length and half 
the thickness of the ampulla. The diverticula are either one or 
two in number, globular, in diameter 06 to ‘12 mm., and attached 
by short stalks to the junction of ampulla and duct. 
The penial setae (fig. 18), in length ‘27 mm. or possibly as 
much as *3 mm., and in breadth 7 near the base, are absolutely 
straight and rod-like; and taper very gradually along the shaft, 
more suddenly at the tip, which is bluntly pointed. There is an 
ornamentation of fine spines at the distal end. 
Remarks.—This is a particularly well-marked species, by rea- 
son of the bands of pigment and the extraordinarily large number 
of spermathecae. It is possible however that it has already been 
described. Michaelsen (10) has given an account of a form which 
he has named P. ceylonensis, also from Peradeniya in Ceylon. 
Unfortunately I am for the present unable to obtain his paper, so 
that I am quite in the dark as to whether this species is or is not 
the same as his. Should it ultimately turn out to be the same, a 
second and independent description of this interesting little worm 
will perhaps not be altogether without value.

Lady Blake’s Drive, Kandy, Ceylon, 22-v-1915 (7. A. Gravely). <A 
single specimen. 
External Characters.—Wength 29 mm., maximum breadth 1°75 
mm. Colour a dirty brown (white in life according to a note 
accompanying the specimen). Segments IIo. 
Prostomium epilobous $, tongue broad, cut off behind. 
The first dorsal pore apparently in furrow Q/Io. 
The setae are widely paired. In the anterior part of the body 
ab =2aa=2bc=cd, and dd is equal to half the circumference. 
Posteriorly ab and cd are a little greater relatively to aa and bc, 
and cd may be rather greater than ab. At the hinder end aa = 
hc=cd or almost so (i.e. the lateral setae are no longer paired) ; 
ab is about 2aa, and dd considerably less than half the circumfer- 
ence. 
The clitellum extends over xiv-xvi=3. 
The male apertures are situated on segment xviii in line with 
setae b, on slightly raised transversely oval areas which extend
