66 Mr. C. R. Narayan Rao on some 
both sides perhaps representing rudimentary spermathecal 
structures. 
Type-specimen in the British Museum. 
Syntypes in the Hamburg and Indian Museums, 
Locality.—Sandy banks of the Harangi, Madapur (Coorg), 
and of the Cauvery, Dubari forests, Fraserpett (Coorg). 
Glyphidrilus saffronensis, sp. n. 
External characters.—Average length of three longest 
specimens 135 mm.; maximum thickness 5 mm., which is 
fairly the thickness throughout, except the posterior one- 
eighth, which gradually tapers towards the anus. Average 
number of segments 298. Segments in the middle of body 
about one-third the width of segments 6-12, and those imme- 
diately in front of the anus about half the width of former. 
Anteriorly the body is round, behind it becomes four- 
cornered with feebly lateral canals, the dorsal and ventral 
ones, however, are strongly marked. Secondary annular 
ridges may be wanting or may be limited to the occurrence 
of one on each segment, mainly anteriorly. 
Prostomium large, zygolobous. In the preserved speci- 
mens the anterior dorsal wall of the pharynx may project 
beyond the mouth. No dorsal pores. Anus, a dorsal 
longitudinal slit, wider at the terminal part with tumid lips. 
The seta-distance in front of segment 12 aa=14, ab=1, 
be=14, ed=1, dd=134; in the middle of body aa=2, 
ab='75, be=14, cd='75, dd=2; in the terminal modified 
portion of body aa=1, ab=°50, be =:75, cd="50, dd=1. 
No trace of clitellum, all the numerous examples in the 
collection being sexually mature; puberty-tubercles and 
clitellar wing absent, 
Nephridial pores, in the intersegmental furrows, nearer 
to seta-line c throughout the length of body from seg- 
ment 18. 
Spermathecal apertures made out with difficulty in the 
intersegmental furrows 13/14-16/17 nearer to seta-line 6. 
Sometimes only one orifice, that of 13/14 may be present. 
Male aperture on the intersegmental furrow 27/28 in the 
seta-space ab ; female opening not discoverable. 
Colour.—In the living condition the whole body is a 
vivid lemon-yellow, with reddish and whitish patches on the 
anterior somites. The terminal modified portion of body 
white. Dorsal and ventral dark bands. In the preserved 
specimens the colour is either a pale yellow or grey. 
Internal organisation——The first recognisable septum is 
4/5, which and the succeeding two are strongly muscular.
