sharply marked off, and not shining. The diverticulum is single, club-shaped, with- 

 out distinct stalk, and in length one-third or one-fourth of the whole main pouch 

 (ampulla plus duct) ; it arises from the ectal end of the duct (fig. 30). 



The penial setae are in length -65- 76 mm., and their thickness at the middle is 

 16/' ; the shaft is straight, the distal end slightly curved, and the tip bluntly pointed ; 

 the ornamentation consists of about eight circles of small spines near the tip (fig. 

 31a). A second shape also occurs, with a somewhat sinuous outline at the distal 

 end, and more sharply pointed tip (fig. 31&) ; this is possibly due to such setae being 

 younger, and not fully straightened out. 



The copulatory setae of segments viii and ix are in length 76- "82 mm., and 22m 

 thick in the middle. The proximal half is straight, the distal portion bowed ; the tip 

 is rather sharply pointed, and somewhat claw-shaped, with a slight swelling just 

 proximal to the point. On the bowed distal portion of the shaft the convex and 

 concave borders are furnished each with a row of spines, or incisions (fig. 32 ; in the 

 example illustrated the spines stand off remarkably clearly ; usually they are closely 

 adpressed to the shaft). 



In the specimen from Poona, the setal intervals were a little different : — in front 

 of the genital region ab = f aa = half be = fee? ; behind the clitellum ab = \aa = f 6c 

 = \ed ; in the middle of the body ab = § aa =■ \bc = ^cd ; dd is approximately f of 

 the circumference. 



The trenches on the male field of the previous example are here contained within 

 a somewhat thickened area, which extends posteriorly to the middle of segment xx, 

 where it becomes joined to a transversely much elongated papilla ; this papilla covers 

 the posterior half of xx and the anterior half of xxi, and transversely is of equal 

 extent with the trenches in front. 



There seemed to be a very thin septum in front of the gizzard, corresponding to 

 6/7 ; 5/6 seemed to be the only missing one. Small ovisacs were present in segment 

 xiv. 



The spermathecal ampulla here has the form of an ovoid sac ; the duct is hardly 

 distinguishable. The diverticulum is a rather cauliflower-like cluster of small seminal 

 chambers, with a short stalk (fig. 33). 



In some of the penial setae the tip, instead of being rounded, appears to have 

 sharp lateral edges. On the copulatory setae also there seems to be a lateral, rather 

 thick ridge on the claw-like tip ; this was more or less distinct in the previous speci- 

 men also. 



In the specimen from Bina, the prostomium might be said to be compounded of 

 the prolobous and tanylobous types, — a tanylobous prostomium with a transverse 

 furrow at the anterior end of the " tongue " cutting it off from the projecting lobe in 

 front. The relations of the setal intervals are scarcely sufficiently different from the 

 type to deserve mention. The seminal vesicles, in ix and xii, were fairly bulky, and 

 their margins were only slightly lobulated.
