64 Mr. 0. R. Narayan Rao 07i some 



minute, sessile, subspherical bodies embedded in the body- 

 wall. Ill eacli segineut there are five on each side, the 

 innermost row internal to seta-line oa, and the others on 

 seta-lines a, h, c, d, with corres|)OiHliiig intersegmental 

 s])erniathccal apertures. Lojj-sided variations in regard to 

 the spermathecaj are common, the additional ones occur in 

 segments 17-18 in the seta-line b. The supra-a>sophageal 

 ganglion occurs in segment 4. 



Type-specimen in the British Museum. 



Syntypcs in the Hamburg and Indian Museums. 



Lucality. — Sandy islets in the Cauvery, Dubari forests. 

 Fraserpett (Coorg) ; banks of Sheravaty, Shimoga (Mysore). 



Glyphidrilus varus, sp. n. 



E.vternal 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 anu.«, become very short, and are marked olf 

 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, 

 hc=l^, ccf=li, dd = 2 ; in the middle of body aa = 'Z'^, 

 «//= 1^, Ac=H, crf=l, dd=2^; in the terminal modified 

 portion of body fl'a = If, uh = ^, hc=\, cd=^^, dd=\^l. The 

 first segment is free. Setie on middle of body very large. 



No trace of clitellum, although all the numerous sjieci- 

 mens in the collection are fully mature and the sexual 

 glands are well developed. Puberty-tubercles and clitcllar 

 wing-like expansions are also absent. The latter may be 

 feebly formed over somites 25-32 on the outer side of seta- 

 line b. 



Nephridial pores in the intersegmental furrows in the 

 middle of seta-space he throughout the length of body from 

 segment 12. 



None of the spermathecal apertures can be made out
