being compressed antero-posteriorly, and so resembling a stout 

 ring; it is obliquely placed, slanting forwards and upwards, i.e. its 

 upper border is anterior to its lower. The gizzard is situated in 

 the middle of the space between septa i; and {^ ; in front of it is a 

 length of oesophagus, behind it a somewhat swollen portion of the 

 tube, from which it is separated by a constriction. Behind 

 septum ^ the canal is narrow as far as xviii, where it becomes the 

 intestine. A very prominent double typhlosole begins in xx. 



In segments xv-xvi are a pair of large white lobed calcareous 

 glands, one on each side of the oesophagus. The lamellae in their 

 interior ran transversely in one case, longitudinalh' in another. 



The last heart is in segment xiii. The missing septa be- 

 tween f and f are indicated by the presence of transverse com- 

 missures ; so that the numbering of the segmc nts is possible even 

 in the absence of the dissepiments. One pair ot commissures 

 (those of segment vi) is situated just behind il ; and there are two 

 pairs close together behind the gizzard and in front of septum » 

 (those of vii and viii). 



The excretory system is micronephridial throughout the 

 body. The nephridia are extremely numerous and close-set in 

 the clitellar region. There are no tufts at the side of the pharynx ; 

 but a considerable number occurs dorsally on the pharynx under 

 cover of the first septum. 



Funnels of comparatively small size, but no testes, were 

 found in segment x in each of two specimens dissected. Both 

 funnels and testes are present in xi, the funnels being consider- 

 ably larger than those in x, and the testes also being compara- 

 tively large. Testes and funnels are not enclosed ; the testes were, 

 however, united with the mouths of the funnels, from which they 

 can be torn apart. 



The seminal vesicles are one pair, in segment xii, attached to 

 the posterior face of septum \\\ they are small in size and compact 

 in form. 



The prostates varied in the two specimens dissected. In the 

 first they were one pair only, each a small glandular tube in 

 segment xvii transversely placed in the segment ; in the second 

 they were two pairs, both very small, elongated in shape, in 

 segments xvii and xix. 



Ovary and funnel were identified in segment xiii, the former 

 consisting of a number of moniliform processes. 



The spermathecae are minute, egg-shaped, lying by the side 

 of the ventral nerve cord. The duct is short, and there is no 

 diverticulum. 



No penial setae were discovered.
