bloodvessels. The intestine begins in xix, after the alimentary tube has escaped from 
the compression of the prostates. 
The last heart is in xiii. 
The excretory system is micronephridial. 
The testes were not identified; funnels were present, free in x and xi. The 
seminal vesicles, attached to the anterior walls of xi and xii, are cut up into small 
ovoid lobules like bunches of grapes. 
The prostates, in xviii, are of moderate size, and cause the septa 17/18 and 18/19 
to bulge forwards and backwards respectively ; they consist of a number of small 
lobes closely compacted together. The duct is short, shining, stout, and even fur- 
ther widened near its termination. 
The ovaries are of comparatively large size, composed of parallel finger-like lobes, 
and break up at their free ends into moniliform strings of ova. 
The spermathecae (fig. 25) are small and numerous, and correspond to the white 
dots seen externally. Each is a club-shaped organ, with a long stalk, and the inter- 
nal end dilated to a greater or less degree; they are disposed more or less parallel to 
each other in a closely set row, their dilated inner ends directed backwards. The 
length varies,—up to I mm.; the breadth at the wider end is about 2 mm. Examined 
in glycerine, the wall is seen to be moderately thick, the greater part of its thickness 
due apparently to a tall columnar epithelium (ep.); in the ectal portion (duct) the 
lumen is narrow, a chink only; the bulbous portion contains a transparent mass (x) 
which nearly fills it, leaving a space (cav.) at the inner end. 
There are no penial setae.

(Plate IX, fig. 26.) 
Parambikulam, 1700—3200 ft., Cochin State; 16—24-ix-1914(F.H. Gravely). A single specimen. 
External characters.—Length I10 mm., diameter 2°75 mm.; colour a medium 
grey, with darker mid-dorsal groove over greater part of length; clitellum rather 
browner. Segments 145. 
Prostomium epilobous +, the longitudinal grooves bounding the ‘tongue’ con- 
verging behind, but the ‘ tongue’ not cut off posteriorly by a transverse groove. No 
appearance of secondary annulation in the anterior segments. | 
First dorsal pore in groove 5/6. 
The dorsal and ventral interruptions in the setal rings differ a little from the 
type form; thus dorsally in front of the clitellum zz=24-1}yz, diminishing backwards, 
while behind the clitellum z2—=2-I#yz, ultimately diminishing so that near the pos- 
terior end the ring is closed. Ventrally, in front aa=24-3ab, behind the clitellum 
—3} ab, and the same towards the posterior end. The setae of the pregenital region 
are on the whole smaller than the rest; a and b are not larger than the other setae, 
and are not in regular lines; ab is not regularly greater than bc. The numbers 
(counted on the two sides) were:—22+23/ix, 21 +24/xiii, 18 +21/xix, and further
