348 Records of the Indian Museum. [Vol. X, 



Length 35 mm., breadth i mm. ; thin, small elongated worms, 

 of an indefinite grey colour. Segments 85. 



Prostomium epilobous J-J. 



Setal ratios estimated as (post-clitellar) ah = \aa=^hc = ^cd. 



Clitellum extends over xiv-xvi=^ 3. The body is narrower in 

 the segments embraced by the clitellum. 



All that could be made out in the genital area was that the 

 setae a of segments xvii and xix were enlarged, and running 

 straight between them, longitudinally on each side (i.e. from seta a 

 of xvii to seta a of xix), was a narrow groove. Setae h seem to 

 be absent on xvii and xix, and both a and h cm xviii. 



A specimen was sectioned longitudinally in order to studj^ the 

 internal anatomy. 



The first septum is 1^, which is thin ; ^ is slightly thickened, 

 '' moderately, ^, ij and to considerably, and vV perhaps slightly. 

 The rest are thin. vSepta f and i are much bulged backwards. 



Dorsal to the alimentary canal in segments iv and v, stretch- 

 ing back from the roof of the pharynx over the dorsal surface 

 of the oesophagus is a gland which at its hinder end almost 

 reaches the anterior end of the gizzard ; laterally also it extends 

 well round the sides of the alimentary tube. The gizzard is in 

 segment vi ; it is small, elongated, with not very thick walls. 

 The oesophagus is narrow in vii, and thenceforward dilated in 

 each segment and constricted at the septa ; the epithelium is 

 folded in all the oesophageal segments viii-xiii, but there are no 

 calcareous glands. The intestine begins in xiv. 



The excretory system is meganephric. 



Testes and funnels are both found in segments x and xi. 

 Seminal vesicles are present as three pairs, in x, xi and xii ; they 

 are dorsalh^ situated, above the oesophagus; those in x and xi 

 meet their fellows above the tube, those in xii do not quite meet. 



The prostates are two pairs ; one pair occupying xvii and 

 xviii, the duct ending in xvii, the other occupying xix and xx, 

 the duct ending in xix. The ducts are bent into a gentle S-shaped 

 curve. 



Ovaries and ovarian funnels, the latter small, are situated in 

 xiii. The oviducts are narrow, and end on the anterior part of 

 the ventral surface of segment xiv, each in front of one of the 

 ventral setae, probably h. 



The spermathecae are situated in segments viii and ix. The 

 ampulla of each is apparently ovoid, and there is a well-marked 

 stoutish duct, longer than the ampulla and bent in its course ; 

 the ducts open in intersegmental furrows I and I. There is a 

 considerable diverticulum, approximately spherical in shape, from 

 the base of the ampulla. 



Genital setae are present in segments xvii and xix, at the 

 apertures of the prostatic ducts, in bundles of two or more. Each 

 is curved to nearly a quarter of a circle ; in length they are ap- 

 proximately 400 /', in breadth 9-10 i>. The extremity is simple, 

 and bluntly pointed.
