then not paired) ; behind the ditellum ab^zjS "^==2/5 bc^4/y cd ; 

 in front of the clitellum rt?)=i 2 aa = i/2 bc=3/5 cd; ^^=4/7 of 

 the circumference. 



The clitellum includes 2/3 of xiii-2/3 xvii ( = 4 1/3). 



The male pores are on xvii, on prominent round papillae 

 which take up the interval between the lines a and b ; round each 

 papilla is a deep trench, the outer margin of which is slightly 

 swollen and indented. The ventral surface of segment xvi is mucli 

 depressed and fissured ; genital markings were present as fol- 

 lows: — In one specimen thei'e were none, beyond the irregular 

 fissuring. Tn a second there were a pair of eye-Uke markings, each 

 an oval rather depressed area with raised margin, behind the 

 setal zone and corresponding to the interval ab, and in addition a 

 similar but circular marking midventrally and in front of the setal 

 zone. In the third specimen the paired markings were present as 

 above ; and in addition a transverse row of four circular markings, 

 touching each other, across the ventral surface in the setal zone. 



The female pores were not made out. 



The spermathecal pores are one pair, in groove 7/8, slit-like, 

 with their centre in ab, rather nearer to a than to b. The middle 

 annulus of segment viii may be raised and " glandular," and 

 small papillae occur variously in this region ; in one specimen 

 there was a small papilla just behind the spermathecal aperture 

 of the right side, and another in the midventral line on the glandular 

 swelling ot segment viii; in another specimen there was a small 

 papilla midventrally on segment ix ; in the third there were no 

 papillae. 



Internal Analomy. — Septum 4/5 is slighth", 5/6 much thick- 

 ened; the next septum is 8/9, which is somewhat strengthened ; 

 g/io is considerably thickened, and lo/ir very stout; septum 

 11/12 is present, though thin (unlike most species of the genus, in 

 which it is absent), and the rest are thin. Septum 8/9 is attached 

 to the parietes a little in front of groove 9/10; septa 9/10 and 

 10/11 are confluent at their insertion into the bod3'-wall, which is 

 situated in the middle of segment x as determined externally, — i.e. 

 midway between furrows 9/10 and 10 11 ; septum 11/12 is normally 

 situated. 



The gizzard occupies the middle of the interval between septa 

 5/6 and 8/9 ; it is large, round and firm ; and the oesophagus in 

 front of the gizzard, between the gizzard and septum 5/6, is also 

 strengthened. There are large dark lateral swellings of the ali- 

 mentary tube in segment xii, but they are not set off from the side 

 of the canal. The intestine begins in xv. 



The last heart is in segment xiii ; that of segment xi is nor- 

 mally situated with reference to septum 11/12, — on its anterior 

 face. There are two transverse vessels in front of sei^tum 8/9 and 

 behind the gizzard (belonging to segments viii and vii), one at the 

 anterior border of the gizzard (segment vi), one in front of septum 

 5/6 (segment v), but none in front of septum 4/5. The dorsal vessel 

 is continued forwards on to the pharynx much diminished in size
