64 Mr. ©. R. Narayan Rao on some 
minute, sessile, subspherical bodies embedded in the body- 
wall, In each segment there are five on each side, the 
innermost row internal to seta-line aa, and the others on 
seta-lines a, 6, c, d, with corresponding intersegmental 
spermathecal apertures. lLop-sided variations in regard to 
the spermathecze are common, the additional ones occur in 
segments 17-18 in the seta-line 6. The supra-cesophageal 
ganglion occurs in segment 4. 
Type-specimen in the British Museum. 
Syntypes in the Hamburg and Indian Museums. 
Locality.—Sandy islets in the Cauvery, Dubari forests. 
Fraserpett (Coorg) ; banks of Sheravaty, Shimoga (Mysore). 
Glyphidrilus rarus, sp. 0. 
External characters.—Average length of three longest 
specimens 205 mm.; maximum thickness 4 mm., which may 
increase slightly behind or suddenly fall from behind 
segments 9-12. The last segments 20-32, immediately 
in front of anus, become very short, and are marked off 
from the rest of the body in front. Average number of 
segments 290; segments 6-10 large; those in the middle 
of the body equal to these or only very slightly shorter. 
The number surrounding the anus is too short to be counted. 
Body round for about twelve segments, behind it is high 
and four-cornered, with broad dorsal, ventral, and lateral 
canals; segments 3-14 bear secondary ridges and annu- 
lations. 
Prostomium large, zygolobous. Mouth is a crescentic 
opening, rather ventral. Anus a narrow longitudinal slit, 
dorsal in position. 
Dorsal pores none. 
The seta-distance in front of segment 12 is aa=2, ab=1, 
be=14, cd=14, dd=2; in the middle of body aa=2?, 
ab=14, be=14, cd=1, dd=2?; in the terminal modified 
portion of body aa=13, ab=#, be=1, cd=?, dd=17. The 
first segment is free. Sete on middle of body very large. 
No trace of clitellum, although all the numerous speci- 
mens in the collection are fully mature and the sexual 
glands are well developed. Puberty-tubercles and clitellar 
wing-like expansions are also absent. The latter may be 
feebly formed over somites 25-82 on the outer side of seta- 
line b. 
Nephridial pores in the intersegmental furrows in the 
middle of seta-space bc throughout the length of body from 
segment 12. 
None of the spermathecal apertures can be made out
