Setce raised on a distinct ridge which is very prominent in the post- 

 clitellar region. There is no dorsal break but a ventral break is present in 

 the preclitellar region. Behind the clitellum the line of Seta a is not quite 

 straight as it is in front of the clitellum, hence the Setje there appear more 

 or less irregularly arranged. 



Preclitellar arrangement aa = l^ab^ bcf> cd 



Setse a and b are larger than others. 



First dorsal pore on the intersegmental furrow J-i pores, indicated on 

 the clitellum also, 



Clitellum as a ring, smooth with no indication of setse or intersegmental 

 furrows, usually xiv — xvi (= 3 segments) in some cases posterior part of 

 segment xiii also encroached on dorsally. 



Male pores on slightly elevated papillae on segment xviii | u apart 14 

 setse intervening. ' 



Female pore on segment xiv on a large papilla in a circular depression. 



Spermathecal pores. — -Four pairs in the intersegmental furrows | — -^ on 

 the ventro-lateral borders. 



Genital markings. — Two pairs of median papillae on segments vii and 

 viii, also a papilla on each of the four segments v — viii just overhanging 

 the spermathecal pores. The arrangement was not so definite in all 

 specimens in some cases there being only one or two on vii and viii 

 segments and no others. 



Internal anatomy. — Septum ■* is the first definite one, septa ^ — | thicken- 

 ed, I — Jo wanting, xi and W also thickened. 



Gizzard between | — i^ somewhat conical, narrower in front than behind. 

 Intestinal co&cce are simple and lie in segments xxvi-xxii. 

 Four pairs of hearts in segments x — xiii. 

 The reproductive organs are lodged in segments x — xxi. 



Male organs. — Two pairs of testes lie in the median testicle sacs in seg- 

 ments X and xi ; these communicate with each other. Two pairs of seminal 

 vesicles in segments xi and xii depending from septa ^f and \\. The 

 seminal vesicles are lobed irregularly. 



Prostates. — Usually one of the two is reduced and the other quite absent ; 

 in a few specimens both were absent. The prostatic duct is however to be 

 seen as a swollen tube showing an inverted S-shaped curve in segment 

 xviii, when prostates are absent, the prostatic duct is then in continuation 

 of the vasa deferentia on each side. 



Female organs. — A large receptacula ovorum is present as a bulging from 

 septum \^ on each side. 



Spermathecce. — Four pairs in segments vi^ — ix. The ampulla is shield- 

 shaped, in outline and well marked oflF from the duct which is slightly shorter 

 than the ampulla. The diverticulum is long, swollen into a knob-like 

 dilatation. ( Fig. VII, Plate II.) 



La?npito mauritii (Kinb.). 



Only one partially dissected specimen in spirit from the new Shalimar 

 side and four specimens from Kapurthala. All these specimens were in the 

 collection of my worthy professor and patron Lt.-Col. J. Stephenson, d.sc, 

 I. M.S., through whose very great kindness I had an occasion of examining 

 this interesting form. I am also indebted to him for allowing me to use 

 his manuscript, notes on the external characters of the Lahore form in order 

 to complete my account of the same. 

 Fvternal characters — 



Length. — 8^ inches, diameter 5 mm., segments 166. 

 Colour. — Dark yellow, darker purplish tinge at the anterior end, 

 Prostomium jjrolobous in the Lahore form while Epilobous in the specimens 

 from Kapurthala.
