Each chfeta is carried on a slight papilla (in the preserved 

 specimen), which is very pale and, indeed, nearly white. 



The prostomium is only slightly, if at all, embedded, but as the 

 buccal region is everted, producing wrinkles on the peristomium, 

 it is impossible to detect the actual limits of the prostomium. 



The clitelhf,m is fully developed and very well-defined, both in 

 front and behind ; it completely surrounds segments 14, 15, 16. 



Genital pores, d'c. (text-fig, 46). — The most remarkable thing 

 about the worm, in which it contrasts with Dinodrilus, is the 

 presence of only one pair of " porophores " bearing the pores of 

 the spermiducal glands, which are situated on the 17th segment

 their true relative distances. The genital pores, nephritic pores, and tubercula 

 pubertatis (T. P.) are also shown. 



in line of b. The papilla is oval, and extends outwards nearly to 

 the level of c ; it is traversed by a spei"matic groove, which passes 

 backwards on the next segment, on the anterior margin of which 

 is a depressed, semicircular prominence, in the same line as the 

 porophore. The spermatic groove ceases some distance in front 

 of the chseta b, so that the male pore is close to the anterior 

 margin of segment 18. 



The ventral surface of segments 16, 17, 18 is pale yellow, and 

 thus contrasts with the grey tint of the neighbouring segments. 

 On the 18th segment there seems to be an oval glandular area
