The oviducal pore is single. No copulatory papillae occur. In the seg- 

 ments directly behind the clitellum; there are 56 à 60 setae, arran- 

 ged in a continuous row; in the region of the spermathecae only 40 

 are to be found, their number usually decreasing in the anterior and 

 posterior segments. Between the male pores 12 setae are present; on 

 the clitellum they are not visible. 



The situation of the first dorsal pore shows some variation in dif- 

 ferent examples, for in some of them I found it lying respectively in 

 the intersegmental groove VI/ VII, VII/VIII or VIII/IX, in other 

 ones even between segment XII and XIII. Two pairs of pores of the 

 spermathecae are visible between segment VII and VIII, and VIII 

 and IX. 



Concerning the internal anatomy can be stated, that the first 

 septum lies between segment IV and V, and that those between 

 segment VIII , IX , X and XI are absent. The oesophagus occupies 

 segment V — VII; the gizzard is situated in segment VIII and IX. 

 Next to it follows the tubular intestine , which shows its wall glandu- 

 larly thickened in segment XI — XIII; the sacculated intestine com- 

 mences in segment XV and is provided in segment XXVI with a pair 

 of long coeca , extending themselves as far as the prostata. Spirally coiled , 

 tubular glands occur in segment V and VI. The dorsal and ventral 

 vessel communicate through four pairs of commissural vessels in segment 

 V, VI, VII and IX; abdominal hearts are situated in segments X — XIII. 



Two pairs of seminal vesicles in segment XI and XII, the first pair 

 reaching into segment X. 



There are two pairs of very large spermathecae, occupying segment 

 VIII and IX; in one example however I observed three of them at 

 the right side of the body, the anterior one in segment VII. Each sper- 

 matheca consists of a large pouch, showing an obtuse coecum at its 

 external side, and of a tubular diverticulum, which is more than 

 twice as long as the pouch and spirally coiled; at some distance from 

 its free extremity the diverticulum shows a constriction and ends in 

 a small oval sac (pi. Ill, fig. 25). The diverticulum of the spermatheca, 

 belonging to segment VIII, is often lying in the preceding segment. 



The prostates (pi. Ill, fig. 24) are large, lobated bodies, thrice as 

 long as broad, occupying segments XV— XXIV and provided with a 

 S-like bend excretory duct.
