relatively large size. L^^mph- glands are again present on the intes- 

 tine from its beginning, appearing as a row of minute lobules lying 

 transversely across the dorsal vessel and attached to the posterior 

 septum of each segment. 



The first transverse vascular commissure is in segment viii, 

 the dorsal vessel, though continued forwards over the gizzard, not 

 giving off any regular series of branches in front (c/, Erythraeodri- 

 lus). The last vessel that can properly be called a heart is in seg- 

 ment xiii ; but, as in the last species, there is a pair of very obvi- 

 ous commissures in xiv. The " hearts " are light in colour, — i.e. 

 muscular and contractile ; they are narrowed at their entry into the 

 dorsal vessel, and in segments xii and xiii appear to have a connec- 

 tion with the supraintestinal also. The commissures of segment 

 xiv are about half the diameter of the hearts, and do not sweep 

 out so far in the segment ; they are dark in colour, and are not 

 contracted at their entry into the dorsal vessel. 



The meganephridia are first plainly visible in segment xx ; as 

 in the last species they are long thin loops stretching outwards on 

 the body-wall to near the middorsal line ; each lies along the mid- 

 dle of the segment, and appears to be quite free from the septum 

 in front. The m.icronephridia are numerous, arranged in a trans- 

 verse band in each segment, though not in a single series ; they 

 form a dense fur all over the inner surface of the body- wall in the 

 clitellar segments ; and in front of this al'^o they are densely set 

 and without regular arrangement ; there are considerable tufts at 

 the hinder angles of the pharynx in segment v. as well as in the 

 most anterior segments in front of this. 



In segments x and xi, ventrally situated and (in xi at least) 

 continuous across the middle line, there were seen fairly large 

 iridescent lobed masses, not enclosed in a membrane, and represent- 

 ing clumps of spermatozoa round the funnels The testes were not 

 distinguished, antl may have atrophied. The vesiculae seminales 

 are two pairs, of moderate size, slightly lobed, in segments ix and 

 xii. 



The prostates are tubular ; the two pairs have the same 

 general arrangement as before. The anterior pair reaches hack to 

 segment xx or xxi, the posterior to xxiv. The ental end of the 

 anterior gland is somewhat narrower than the main mass of 

 the gland ; in segment xix the main mass becomes a narrow shin- 

 ing duct, which crosses segment xviii, twisting about as it does 

 so ; the duct ends, widening rather rapidly, by getting into xvii 

 and piercing the body-wall at the posterior border of the segment. 

 In the posterior pair there is not much difference in the thickness 

 of the glandular part throughout its extent ; each becomes a nar- 

 row shining duct at the anterior border of segment xxi ; this duct is 

 convoluted as it crosses xx, widens as it enters xix, and, as seen 

 from inside, pierces the body- wall at about the middle of the 

 length of the segment. In both the anterior and posterior glands 

 the terminal portion of the duct is directed inwards towards the 

 middle line.
