Remarks.—I have only had a few specimens of this worm. 
It is very like M. grandis, and occurs along with that species. 
It is easily to be distinguished from M. grandis by its small, 
pointed prostomium. The whole anterior end is pointed, and 
when killed in spirit it is flaccid, while M. grandis is for a 
time very rigid. 
M. nilamburensis, sp. n. 
Prostomium broad. 
Size, 760 mm. long, 23°5 mm. in circumference. 
Segments, 566, annulated. 
Pigment, very little present. 
Setz 0°63 mm. long. They appear black to the naked eye. 
Dorsal gap 14 mm., lateral gaps 3 mm., ventral gap 3-5 mm. 
Each couple is separated by 0°5 mm., and are therefore more 
widely separated than usual. 
Nephridiopores all, I think, in the direction of the outer 
seta rows. 
Male pores nearer the inner seta rows than the outer. 
Oviducal pores in the direction of the inner seta rows. 
Spermathecopores in the direction of the outer seta 
rows. 
Septa v-vi to vii1-1x very thick. 
Gizzard in five (or six) lobes, occupying about Segments 
XXVIII—XXXIII (normal for five lobes, the sixth lobe may be in 
XXVII OF XXXIV). 
Sperm-sacs oval. 
Prostates 7 
Ovaries : 
Spermathece eas in M. grandis, 
Copulatory pouches 
Habitat.—I have had preserved specimens only from 
Nilambur, near the sea-level, which were kindly sent me by 
Mr. Hadfield, of the Forest Department, who informs me that 
the worm burrows along in the wet season just underneath the 
surface. 
Remarks.—This is another worm like M. grandis. It is
