144 Memoirs of the Indian Museum. [Vol,. I, 



Head prolobous; prostomium transversely oval. 



Setae strictly paired, especially the lateral ones. In general middle lateral dis- 

 tances about equal to the ventral median distance, at the anterior part of the body 

 very little larger {aa < he, at the anterior part of the body aa = ca. i| he). The median 

 dorsal distance is somewhat larger than half the circumference of the body 

 {dd=Q.3.. f w). 



Nephridial pores in the lines of setse cd. 



Dorsal pores apparently absent. 



Clitellum ring-shaped, occupying segments lo — 13 (=4). 



Male pores on the top of transversely oval papillae in the intersegmental furrow 

 10- 1 1 in the lines of setae h; the male papillae transgress the lines of setae h laterally 

 somewhat further than the lines of setae a medially. 



In a great number of specimens there was an additional pair of rudimentary 

 male pores on the intersegmental furrow 9-10, in the same lines as the true male 

 pores. These rudimentary male pores were always somewhat, very little or distinctly, 

 smaller than the true male pores, and their papillae were not quite as prominent : they 

 were seen in all the mature specimens from Bilaspur as well as in most of the half 

 mature ones from this locality, but in the latter in a very different degree of distinct- 

 ness, corresponding to the degree of maturity In many young specimens from this 

 locality the true male pores were already distinguishable, whilst there was not yet 

 any trace of the additional ones. These, therefore, seem to be developed later than 

 the true male pores. As for the specimens from Hyderabad, I could detect an 

 additional male pore only in one of the three mature ones, and only on, one side of 

 the body. 



P'emale pores on the intersegmental furrow 11-12, in about the lines of setae 

 ah (only seen in sections). 



Spermathecal pores on the intersegmental furrow 7-8 in the lines of setae «ô 

 (inconspicuous) . 



Internal Anatomy, — Septa 6-7 — 8-9, very strong, especially the first two; 

 septum 9-10 tender, but apparently a little bit thicker than the very tender following 

 ones. Septa 9-10 and lo-ii are dislocated backwards dorsally, especially the latter, 

 which is dislocated for about half a segment's length. 



Alimentary tract: CEsophagus simple. Two rather big muscular gizzards in 

 segments 14 and 15. The oesophagus seems to be somewhat thickened and provided 

 with a stronger muscle layer in the 13th segment, but a distinct gizzard is not devel- 

 oped in this segment. Intestine, at least in the anterior part, without typhlosole. 



Nephridial system meganephric. 



Male organs: One pair of big seminal vesicles on septum 9-10, restricted 

 by it, depending from it forwards into the 9th segment and backwards into the loth 

 segment. A big tuft-shaped test enclosed in each seminal vesicle fixed to it ventrally 

 in the restricted zone of septum 9-10. A fiat sperm-duct-funnel in each seminal 

 chamber united to its ventral wall behind the test. Sperm-ducts very long, coiled, 

 in segments 9 and 10. I could not detect the mode of entering into the prostates.
