segment 14, and not quite I'eachiiig tlie line of a on either side. 

 This tubercle is absent in some individuals. 



The oviducal pores are wide apart, nearly in line of «, but a 

 little mediad. 



The two pairs of spermathecal pores are distinct and slit-like, 

 about midway between the chseta a and the posterior margin of 

 each of the segments 8, 9. 



Dorsal pores are present, at lea,st in the postclitellai- region.

Internal Ancdomy. 



The last heart is in segment 12. 



The gizzard, though small, is distinct. 



The micronephric tubercles are moi-e delicate than in other 

 species, and all concentrated to form a latero- ventral mass on each 

 side. 



The prostates extend back to segment 23 ; the duct is nari-ow 

 and rather long, and between the paii- of ducts lies a great 

 glandular mass, which thrusts the anterior ends of the prostates 

 outwards, so that the duct is transverse. 



Each of the spermathecpe (text-fig. 82), in segments 8 and 9, 

 consists of a pyriform sac w-ith a very thick duct, thicker than 

 the neck of the sac. A small tubidar diverticulum, dilated 

 terminally, opens into the duct neai- the body-wall.
