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



In the third, undissected, specimen of the original batch, the 

 male papillae are not more than one-seventh or one-eighth of the 

 circumference apart. There is one pair of slightly marked sperma- 

 thecal papillae, — slight whitenings of the surface rather than 

 definite papillae, — in the line of the setae of segment viii, the 

 interval between them corresponding to that between the male 

 pores ; no second pair is indicated. This specimen was probably 

 not as fully mature as the others. 



I may now briefly describe the specimen in the present collec- 

 tion 



External chayacters. — Length ^o mm ; diameter 2 mm. Colour 

 grey (original colour ?). Segments 64, 



Prostomium ? (buccal cavity everted). 



Dorsal pores from furrow 3/4. 



Setae in rings; middorsal interval small, = 2yz 01 less; mid- 

 ventral also small, == about i^ah. There appeaj to be about 34- 

 36 setae per segment both in front of and behind the clitellum, and 

 28 towards the end of the fragment. 



Clitellum smooth, brown in colour^ extending over -^xiii-l-xvi 

 = 3 ; setae indicated. 



The male apertures, on segment xvii, are not very close 

 together, — about a quarter of the circumference apart ; they are 

 situated on whitish papillae which take up the whole of the space 

 between the line of the setae and the furrow which limits the 

 segment posteriorly. 



The female aperture is single and conspicuous, on segment 

 xiv, in a whitish circular patch situated between the line of the 

 setae and the anterior border of the segment. 



The onl}" signs of apertures in the spermathecal region are a 

 pair of small pale papillae, not very easily distinguishable, in the 

 line of the setae, about in the situation of seta d. 



There are no other genital marks 



Internal anatomy. — The septa are all thin. • 



The gizzard is large and barrel-shaped. Calcareous glands 

 are present in segments x, xi, and xii ; there is no marked difference 

 in size throughout the series. 



The last heart is embedded in septum 13/14, which is bulged 

 backwards, so the heart at first appears to be in segment xiv ; it 

 really however belongs to xiii. 



The meganephridia begin from segment xx. 



Testes and funnels are present in segments x and xi ; in xi the)'' 

 are contained within testis sacs, — large soft structures, much resem- 

 bling seminal vesicles ; in segment x they are also probably in sacs, 

 though this was not so clearly demonstrated. The vesiculae serai- 

 nales are in segments ix, x and xii ; they are large, soft, and not 

 much cut up into lobes ; those in xii meet over the alimentary 

 canal. 



The tubular prostates are one pair ; each is a series of simple 

 loops which begins behind about segment xx, passes forwards to xvi, 

 and then bends back again ; succeeding the glandular part is a
