390 Records of the Indian Museum. [Vol. VIII, 



The clitellum embraces segments xii-Jxix=7^; the region is 

 swollen, but the intersegmental furrows are not obliterated. In 

 dissection this portion of the body-wall is very thick and friable. 



The first dorsal pore is in furrow ;] ; no pores are however 

 visible on the Clitellum. 



The setal rings are unbroken ventrally ; the setae are very 

 close together in the mid- ventral region; the intervals become 

 wider towards the sides, and laterally and dorsally are three times 

 as wide as mid- ventrally, or even more. The ring is broken in the 

 mid-dorsal line {zz = 2^-'^yz) ; but the dorsal setae are extremely 

 difficult to see, and are so small that I was at first uncertain 

 whether or not any existed posterior to the clitellum. There are 

 no setae between the male pores on the ventral surface of segment 

 xviii ; otherwise the setae of the clitellar segments have the usual 

 distribution. The number of setae per segment is about 50. 

 There are no penial setae. 



The male pores are situated on the lateral margins of a 

 square depression which occupies the mid-ventral portion of seg- 

 ment xviii. The size of the depression is such that it occupies 

 the length of the segment from the anterior to the posterior 

 limiting groove. The margins of the pores themselve? are 

 puckered or nodular. 



The female pore is single, and minute, situated in the middle 

 of a slightly depressed whitish patch mid- ventrally in the anterior 

 part of segment xiv. 



The spermathecal apertures are two pairs, inconspicuous, in 

 grooves 7 and f, about \ of the circumference apart. 



There are no other genital papillae or markings. 



No septa are specially thickened. 



There is not even a rudimentary gizzard. The oesophagus is 

 rather dilated in segment x ; the intestine begins in xix ; there 

 are no intestinal caeca. 



The last hearts are in xiii, the first, which are small, in vii. 



The nephridial system is purely meganephric ; all the organs 

 on each side are in the same line. 



The sperm-funnels are large and iridescent, free in segments 

 X and xi. The vesiculae seminales are paired, in xi and xii, 

 depending backwards from the anterior septum of their segments ; 

 they are large, compact masses, only indistinctly cut up into 

 lobes. The vas deferens, thin and fine, joins the prostate gland 

 on the lower part of its inner face, close to where the ejaculatory 

 duct leaves it. The prostate occupies segments xvii and xviii, 

 and septum \i> is bulged backwards by the gland ; it is a solid- 

 looking massive compact body, elongated antero-posteriorly, not 

 distinctly lobulated on the surface; its duct is thick, short, and 

 S-shaped. 



The ovaries are large, like bunches of grapes. 



The spermathecae are in segments vii and viii, their apertures 

 in grooves y and ^. The shape of the ampulla is very irregular, 

 and not quite the same in all (fig 11) ; on the whole it is triangular.
