Records of the Indian Museum. [Voi,. XXIV, 



The nephridiopores are just above the line of setae b. 

 The clitellum is saddle-shaped, and extends over segms. xxix- 

 xxxiv (= 6). The ridges of puberty are indistinct, and appear to 

 be coextensive with the clitellum, or perhaps exclude the last 

 segment and half of the first. 



The male pores are on segm. xv; they appear as transverse 

 slits which extend from the line of setae b to that of c, with 

 tumid anterior and posterior lips which cause the limits of seg- 

 ment xv to bulge forwards and backwards. 



The spermathecal apertures are in furrows 9/10 and 10/11, in 

 the line of setae d. 



Internal Anatomy :— Septum 4/5 is thin, 5/6 -- 15/16 are thick- 

 ened, 6/7-8/9 most so, the rest only slightly. 



The gizzard takes up two segments ; xvii and xviii. There 

 are oesophageal pouches in segm. x ; the calciferous glands in xi 

 form large lateral widenings of the oesophagus which, however, 



are not set off from the tube ; they are 

 continued back, but are less prominent, in 

 xii, and are not distinguishable behind this. 

 The last heart is in xii, but this is much 

 smaller than the one in xi, and is at a 

 deeper level. . 



Testes and funnels are free, in segms. x 

 and xi. There are four pairs of seminal 

 vesicles, in segms. ix-xii, all of quite 

 moderate size ; those of segm. x are equal 

 in size to those of ix. 



Spermathecae are present in segms. x 

 and xi as small round sacs sessile on the 

 body-wall. 



The ventral setae of segm. xv are slightly 

 modified. The points are apparently soft- 

 ened ; the characteristic feature is a faint 

 sculpturing of the distal portion of the 

 shaft by a numerous series of transverse 

 markings, slightly jagged and convex towards the insertion of the 

 seta (fig. 5).
