THE EARTHWORMS OF LAHORE. 501 



rentia go side by side separately and are covered by the large masses of 

 ramifying nephridial tubules, they are contives separately in the thickened 

 and curved prostatic duct and do not open into the gland. (Fig. Ill, Plate 

 II.) This is a difference from what has been stated by Lt.-Col. J. Stephenson,. 

 D.Sc, I. M.S., in his paper (3). The vasa deferentia it appears unite with the 

 prostatic duct at its ending point only. 



The prostates are large occupying segments xvii-xviii divided up into a 

 corresponding number of lobes by the septa ; there is a very deep notch on 

 the inner side in segment xix and continued upwards in segment xviii as 

 well. The thick yellow duct begins in this notch in segment xix and after 

 making an S shaped loop opens at the male pore in segment xviii. Moreover 

 it was noticed that there are five additional primary prostatic ducts from the 

 lobes of the prostate beginning in the substance of the gland and coming to 

 open into the thick yellow duct. No account of these was given hitherto in 

 all the literature consulted. 



Accessory prostates in segments xvii, xviii and xix corresponding in posi- 

 tion to the papillse on the outer surface are to be seen. A glandular mass 

 in segment vii was also to be seen in the position of the papilla externally. 



Female organs. — The ovaries are large masses connected with the septum 

 i|. and laying in segment xiii. Oviduct funnels lie in xiii, the oviducts of 

 the two sides as far as could be followed did not unite but appeared to 

 open separately. A large receptaculum ovorum formed as a bulging in 

 septum yI could also been seen internally to the funnel of the oviduct. 



SpermatheccB 2 or 3 pairs mostly two. 



The ampulla is ovoid in shape with a small protuberance at the head, it 

 narrows gently into the duct which is well marked and slightly longer than 

 the ampulla. The diverticulum is a thin narrow tube slightly dilated in its 

 distal portion ; it reaches nearly to the half of the ampulla. (Fig. IV, Plate 

 II,) The diverticulum arises quite close to the base. 



Fheretima hatvay ana —snhsTpecies barbadensis (Beddard). 



Found all over Lahore in fairly large numbers. 

 External characters — 



Length. — 90-120 mm., diameter 4 — 4f mm., segments 85^ — 92. 

 Colour. — Dirty yellow to brown. 



Frostonium epilobous, (|.) Segments i — iv consist of single annxili v-vi of 

 two annuli each, all the rest of three annuli each. 



Setae in unbroken rings, clitellum usually without setse but one sexually 

 mature specimen from the Bhati gate gardens had 3 distinct rings of setee 



on it. Numbers of setse ^ £j -j- and 60 usually in the hinder segments. 



First dorsal pore in the intersegmental furrow ^, the pores are dis- 

 tinctly visible on the clitellum as well. 



Clitellum as a ring xiv-xvi (=3 seg.); very much darker in colour and of 

 8 much lesser diameter than the rest of the body. (Fig. 3, Plate I.) 



Male vores on raised ovoid papillse on segment xviii |m apart, 21 setee 

 intervening. 



Female pore in a deep transversely elongated depression on the anterior 

 part of segment xiv. 



Spermathecal apertures usually two, seldom three pairs in the intersegmen- 

 tal furrows i 4 or |-g. 



Genital markings. — Three papillae surrounding the male pore on each side, 

 in some cases one or two papillee on segments xvii and xix are also seen. 

 One or two papillse on segments vii and viii are also seen a little in front of 

 the setal rings. 



Internal anatomy. — First definite septum is f . Septa f and ^ moderately- 

 thickened, I, I wanting and the septa f^ — \\ are also thickened.
