412 Records of the Indian Museum. [Vol. XIII, 



The spermathecal apertures are possibly represented by whit- 

 ish patches on segment viii in the site of the ventral pair of setae 

 {ah) ; a single seta, apparently b, is present in each patch. 



There are no other genital markings. 



Internal anatoinv. — Septa 4/^ to 7/8 are thin ; the rest of those 

 in the anterior part of the body, — 8/9 to 12/13, — are slightly 

 strengthened. 



The gizzards are large, in segments v and vi. Calcareous 

 glands are present as small white swellings in segments x, xi, and 

 xii. The typhlosole is a simple vertical lamina. 



The last heart is in segment xii. 



The excretory system is micronephridial ; the arrangement 

 varies a little in various parts of the body. Behind the prostatic 

 region the nephridia are in three or four rows, of which the dorsal 

 row consists of more elongated loops than the rest ; the organs 

 are not of the fiat circular type met with in some species, but are 

 thin tubes in the form of loops ; if there are four rows, the two 

 ventralmost are close together. Behind the middle of the body 

 there are three rows, of the same relative size as further forwards. 

 Near the hinder end the lowermost of the three nephridia increases 

 relatively and absolutely in size, and is the most conspicuous of 

 the three, — a twisted tube which has its inner end in the line of 

 setae a and its outer end external to b ; of the other two, one lies 

 between c and d, and the other dorsal to d; these two are less 

 easily seen. 



In segment x are a pair of large opaque white shining masses 

 with deeply lobulated margins ; these are the most prominent 

 things in the dissection ; they are attached to septum lo/ii, meet 

 each other in the middorsal line above the other structures of the 

 segment, and extend deeply down in the segment but without be- 

 ing attached to the ventral body- wall. These represent testis-sacs 

 and seminal vesicles conjoined; on opening one, a funnel was 

 found deeply placed, but the testis was not identified. There are 

 no other anterior male organs. 



The prostates, one on each side, are very small; they are 

 situated in segment xvii, and are placed in a direction transverse 

 to the long axis of the body. The duct is much narrower than 

 the gland, of the same diameter throughout, and rather bent ; if 

 straightened out it would be almost as long as the glandular por- 

 tion ; the general direction of the duct is transversely inwards. 



The ovaries are situated in segment xiii. There are a pair of 

 well-marked and relatively large ovisacs in segment xiv. 



The spermathecae lie in segment viii ; each is a twisted tube, 

 without distinction of ampulla and duct. On one side (fig. 32, a) 

 the tube appeared of equral diameter throughout, except for a slight 

 dilatation at its ental extremity ; on the other side it was more 

 irregular (fig. 32, b, which represents it under the low power of the 

 microscope). The external opening is near the middle line and be- 

 hind the anterior limit of the segment in which they lie,— possibly, 

 as surmised from the external characters, in the situation of setae
