The prostatic pores are one pair, on segment xvii, situated on 

 round papillae which take up the interval between the lines a 

 and h ; they are slit-like, and obliqxiel}- placed, diverging from 

 each other backwards. 



The female apertures are minute pores in a circular white 

 patch on the anterior part of segment xiv. 



The spermatheca' apertures are represented by a pair of very 

 minute white points on segment viii, just in front of setae a. 



Iniernal Anatomy. — Septum 4/5 is thin, 5/6 extiemely tenuous. 

 6/7 and 7/8 also very thin; 8/q is thin, 9/10 and lo/ii slightly 

 strengthened; 11/12, 12/13 and 13/14 are thin, but slightly 

 strengthened by comparison with those that follow (the specimen 

 was in a poor state of preservation, and possibly the septa are 

 normally somewhat thicker than the above description would lead 

 one to suppose). 



There are two gizzards, in v and vi, of comparativelj^ large 

 size, firm and rounded. Calciferous glands are present in segments 

 X, xi and xii, not stalked, and diminishing in size backwards. 

 The intestine begins in segment sv. 



The last heart is in segment xii. 



The excretory system is micronephridia!. The organs are of 

 relatively moderate size ; in front of and in the clitellar region 

 they are scattered ; behind the clitellar region they form a trans- 

 verse row of four (three to five) on each side in each segment, 

 those towards the ventral end of the row being smaller and closer 

 set. About 27 segments from the hinder end the innermost 

 nephriduim of each row enlarges and the arrangement comes to 

 be as follows: — one nephridium, a lone thin loop between seta 

 d and the middorsal line ; one small, lying in line c ; and one, the 

 largest and thickest extending from a outwards to between h and 

 c ; the series thus consists of three on each side. 



There is a pair of large and conspicuous male funnels in 

 segment x,and a smaller pairiir xi. On the other hand testes were 

 identified in xi, but not in x. No seminal vesicles were present. 



The prostates are one pair, in xvii, small, tubular, and placed 

 transversely in the segment. The duct, also transversely placed, 

 is thin, and in length equal to the glandular portion. 



The female organs have the usual situation. 



The spermathecae (fig. 12) are one pair, situated in segment vii ; 

 they open externally as described above, on segment viii, septum 7, 8 

 being rather obliquely placed. Each is a narrow elongated some- 

 what cylindrical tube, "66 mm. long, slightly curved, and rather 

 wider in its ectal portion ; a short terminal section which narrows 

 to its insertion into the body-wall, may be described as the duct. 

 A small sac-like diverticulum is given off from the junction of 

 ampulla and duct. 



The penial setae (fig. 13) are -53 mm. long, and very slender, 

 2'5/n in thickness ; they are bowed towards the distal end, where the 

 shaft is twisted and somewhat sinuous in outline ; the tip however 

 is straight, and ends in a small rounded flat expansion which al-
