and encroaches in front and behind on the adjacent segments ; the 

 depression is rectangular in shape, atid has a well marked border, 

 — rather less well marked however at the sides, near the male 

 pores. These are round pits with distinct lips, situated very close 

 together slightly behind the middle of the segment, the line of the 

 setae bends forwards in front of the apertures. 



The female aperture is single, and appears as a small trans- 

 versely elongated pit, on segment xiv, midway between the line 

 of the setae and the anterior limiting furrow. 



The spermathecal pores are situated in furrows yj^ and 8/g, 

 fairly close together, but not, apparently, as close as the male 

 pores. 



There are no other genital marks. 



Internal anatomy. — Septum 4/5 is thin, 5/6 slightly and 6/7- 

 11/12 somewhat or moderately thickened ; a number of those that 

 follow, as far perhaps as 18/19, ^^^^^ slightly thickened. A large 

 number of Nematode parasites were found in some of the anterior 

 segments, in x and especially in xi. 



The gizzard, in segment vi, is of fair size even relatively to 

 the large size of the animal ; it is moderately firm though not hard ; 

 the anterior end is the broader, and there is a constriction not far 

 behind the anterior end, where a transverse sheet of muscle (not a 

 septum) is inserted round the organ. There are no calcareous 

 glands. The intestine begins in segment xviii 



The meganephridia are disposed in the same longitudinal line 

 throughout the body. 



The last heart is in segment xiii. 



Free funnels were found in segments x and xi, and testes in 

 the former segment ; testes were not identified with certainty in xi 

 but the condition of the specimens left something to be desired, and 

 this segment was packed with the Nematode parasites mentioned 

 above. Vesiculae seminales are present in xi and xii ; they are 

 large, soft, and somewhat cut up into lobes at their surfaces ; those 

 in xii are large enough to bulge back the septum ; in one specimen 

 those of the same segment had fused together over the intestinal 

 canal, in the other those of the two sides were separate. There 

 appears to be, in addition to the above, a small empt}' rudimen- 

 tary seminal vesicle in segment xiii, attached to the posterior face 

 of septum 12/13. 



The prostate, of the Pheretima- type, is confined to segment xix ; 

 it is cut up by indentations into lobes, and the short and stout 

 though soft duct runs from the hilus transversely inwards to 

 its exit. 



Ovaries were present in segment xiii, attached to the poste- 

 rior face of septum 12/13 ; the funnels were not seen. In both 

 specimens rudimentary ovisacs were seen in xiv. 



The spermathecae have the simplest possible form, — almost 

 spherical sacs, prolonged into a short thin duct. There are no 

 diverticula, though the ampullae themselves show a warty promi- 

 nence or two
