Dorsal pores begin in groove 1/2 ; this must be about the extreme anterior limit 

 which they ever attain, though I could not say that it is unique. Beddard (1 ) 

 states that dorsal pores are never found on the first one or two segments of the 

 body. 



The setal rings are interrupted dorsally ; in front of the clitellum zz—'$yz, and 

 behind =about zyz ; but behind the clitellum the interval itself, as well as the inter- 

 setal intervals on each side, is irregular. The ventral break is absent, or small and 

 irregular. On the ventral surface the setae are small and very close together, — almost 

 as close as they can be. For this reason, and also because of the dark colour of the 

 animal, they are very difficult to count ; behind the clitellum there are about 60, 

 and further back 64. 



The clitellum is extensive, from xi to xx ( = 10); it is slightly swollen, less 

 marked or absent ventrally, rather darker in colour, and dorsal pores are absent. 



The male field is situated on segment xix (whether normally, or exceptionally in 

 this particular specimen, cannot be said). It consists of a mid-ventral rectangular 

 area, rather broader than long, which takes up most of the length of the segment ; 

 it is delimited at the sides by slight grooves and in front and behind by deep tren- 

 ches, which coincide with the intersegmental furrows ; the trenches are however 

 much broader than the intersegmental furrows, and encroach anteriorly and post- 

 eriorly on the surface of the segment. The pores are apparently on two small whitish 

 papillae very close together near the mid ventral line. 



The female pore was not visible. 



The spermathecal apertures are two pairs, in grooves 7/8 and 8/9, close to the 

 middle line. 



Internal Anatomy : — No septa are specially thickened. 



There is no gizzard, even vestigial. The pharyngeal glands are especially bulky, 

 and extend as large masses on the alimentary canal backwards to segment ix. The 

 oesophagus is bulged laterally, and its walls are vascular, in segments x-xiii. The 

 intestine begins in xvii. 



The last heart is in segment xii. 



The nephridia end in approximately the same line. 



The male funnels (presumably testes also) are free in segments x and xi. 



Seminal vesicles occupy segments xi, xii, and xiii. They are relatively small, 

 are attached to the anterior wall of their segment in each case, and have a racemose 

 appearance owing to their being composed of a number of small lobules ; indeed the 

 extremely racemose appearance of those in segment xiii caused them momentarily to 

 be mistaken for ovaries. There appeared to be an additional minute pair of racemose 

 vesicles in xiv also. 



The prostates, in segment xix, are small, and consist of a number of elongated 

 finger-like lobes, the whole forming a bushy cluster. The duct is small, soft, not 

 much thickened, and runs transversely inwards. 



Ovarian funnels were identified in xiii. 



The spermathecae (fig. 22) are situated in segments viii and ix. The ampulla is
