unbroken ring. The setse are somewhat enlarged on segments vii and viii. 

 Clitellum all over devoid of setse but in some specimens there were setse on 

 segment xvi ventrally. Numbers of setse — -r^ 



XIX XXVI 



First dorsal pore in the intersegmental furrow i-^ the dorsal pores are 

 easily seen on the clitellnm as well. 



Clitellum as a ring from about | xiv or xiv — xvi (= 2f or 3 

 segments). 



Male pores on small papillae on segment xviii about g u apart, 18 setse 

 intervene. 



.Female pore in a transversely extended depression midventrally on 

 the anterior part of segment xiv. 



Spermatheeal pores usually two, in some cases three pairs of openings in 

 the intersegmental furrows | — | or | — |. In an abnormal specimen there 

 were two spermatheeal pores in the furrow |- on the right side correspond- 

 ing to two spermathecse in segment vi on the right side and one on the 

 left side. 



Genital markings. — Usually 3 papillae, surrounding the male pore on 

 segment xviii, are situated on an oval glandular patch of skin, the papillse 

 merge into one another. Internal to the male pores at a slightly posterior 

 level behind the setal ring two to seven papillse more are to be seen. Five 

 to seven papillse are seen on each of the segments xvii and xixalso. Two or 

 in one case four papillse were seen on the segment vii and a single one 

 sometimes on the viii segment as well. The papillse were rather conical 

 projections with a dark centre. 



Internal anatomy. — First definite septum |. Septa I and f moderately 

 thickened, |, i% absent, \% — i^ also somewhat thickened. In some cases 

 a rudimentary septum ^-^ resent. 



Alimentary tract consists of the following parts : — The Buccal cavity in 

 the first two segments is followed by the Pharynx i — iv with large pharyn- 

 aeal glands in segments iii and iv situated dorsally as well as laterally, no 

 internal openings of these glands into the pharynx could be discerned. 

 Oesophagus occupying segments v — vii with lateral pouches in vi but no 

 • calcareous glands ; these lateral pouches were very large in some cases. 

 Gizzard in segments viii and ix as a thickened globular sac with a conical 

 posterior end. Intestine rather thin up to septum \t then becomes wider 

 and passes to the end unchanged. It is covered all round by a thick 

 layer of yellow chloragogen cells. The typhlosole is seen as a very small 

 ridge dorsally projecting into the cavity of the intestine. Intestinal 

 diverticula hollow, conical, beginning from segment xxvi and continued 

 forward to segment xxi. There are from five to seven secondary diver- 

 ticula of a roundish appearance on the primary diverticulum of each 

 side. 



There are four pairs of hearts in x — xiii, there are also a pair of palmate 

 blood glands lying on each side of the dorsal blood vessel in each segment 

 after the xxiii segment. 



The nephoridia are of the inicro-nephric type, diffused on the body wall 

 as well as on the septa. Two large, masses of these nephridia, very richly 

 supplied by blood vessels, were also seen on each side of the oesophagus 

 in segment vii. 



The reproductive organs are lodged in segments x — xxii. 

 Male organs. — The two pairs of testes lie in the median testical sacs in the 

 segments x and xi. The lateral seminal vesicles lie in the segments xi and 

 xii depending posteriously from septa ^^ and i|. These are irregularly 

 lobulated. The vas deferens in connection with the seminal funnel lying in 

 segment curves over the one from the anterior segment, and this vas deferens 

 goes along the outer side of the one from the anterior sac. Both the vasa defe-
