[Vol.. I, 



ab=l aa=^bc=^cd. In the anteclitellar region and at the hinder end of the body 

 the setae are nearly separated : aô =ca. f c^ = |- &c = f aa. Setae all at the ventral part 

 of the body, the median dorsal distance being somewhat larger than half the circumfer- 

 ence {dd =:C3.. fu). 



First dorsal pore at the intersegmental furrow 12-13. 



Clitellum ring-shaped, but ventrally depressed and thinner, less glandular, 

 occupying the segments ^ of 13 — 17 ( =4^)- 



Male pores in the 17th segment lateral of, if not in, the lines of setae b (here at 

 least the penial setae are arising) , in the lateral part of deep transverse slits or grooves 

 which surpass a little the lines of setae a as well as those of setae b. The body- wall 

 lateral of and behind the grooves of the male pores is somewhat elevated, the body- wall 

 before them somewhat depressed. 



Female pores at the 14th segment anterior to the zone of setae, a little lateral 

 from the lines of setae a, nearly touching these lines. 



Spermathecal pores one pair at the intersegmental furrow 7-8 in the lines 

 of setae c, in the centre of transverse eye-shaped areas. 



Copulatory organs intersegmental transversely oval areas or glandular slits 

 in the lines of the ventral pairs of setae, somewhat transgressing these lines. Nearly 

 constant on the intersegmental furrows 14-15, 15-16 and 18-19, 

 those of 14-15 as well as those on 18-19 being absent only in two of 

 the twenty-four specimens ; rarely (twice) an additional pair on 

 19-20, often similar areas on 16-17, just before, and with the 

 hinder part drawn back into the slits of, the male pores. In one of 

 the ten specimens from Mainpuri, and in all the specimens (fourteen) 

 from Pusa, there was a pair of somewhat different copulatory 

 organs, — a kind of eye-shaped papillae in the intersegmental furrow 

 9-10 in the lines of the ventral pair of setae. 



Internal Anatomy. -Septa 6-7 and 8-9 — 10- 11 very thick, 

 7-8 missing. 



Alimentary tract: A big gizzard between septa 6-7 and 

 8-9. CEsophagus in the 12th segment swollen, globular, containing 

 a pair of thick lateral calciferous glands which have the shape of 

 hemispheres. Intestine from the 14th (15th ?) segment, with a 

 big simple typhlosole, beginning not before the 22nd (?) segment. 



Circulatory system: Dorsal vessel simple, last hearts in the 13th segment. 



Nephridial system micronephric. 



Anterior male organs: A pair of large sperm-duct-funnels ventrally in the 

 nth segment, touching in the middle and enclosed in a common seminal vesicle. 

 One pair of large, much lobed sperm-sacs depending from septum 11-12 into the 12th 

 segment. 



Prostates tube-like, very long, occupying about three segments. Glandular 

 part convoluted ; muscular duct thinner and very much shorter than the glandular part, 

 nevertheless about 6 mm. long.
