THE OLIGOCH^TA OF NATAL AND ZULULAND. 439 



tion is Beddard's specimen, and it bears only one pair of 

 papillae on the eleventh segment. Generally there is a pair 

 of papillae on the eleventh or on the thirteenth segment, if 

 there ai-e not pairs on each of the three segments 11-13. 

 While the papilla? on the twelfth segment are very large and 

 prominent, those of the eleventh and thirteenth are often 

 very small, or at least one is very small, if there are three 

 pairs. The papilla? of the eleventh segment in both specimens 

 examined by Beddard differ from the othei-s by occupying 

 the place of the lateral sette. In Beddard's figure these 

 papilla are situated between the ventral and the lateral pairs 

 of sette, and both of these pairs are shown in the figure in 

 addition to the sexual seta? of the papillae. A re-examination 

 of Beddard^s specimens shows that the sexual setas of the 

 papillae on the eleventh segment are really the transformed 

 lateral sette, and the papillte lie in the lines of the lateral 

 setae although somewhat shifted in position. The normal 

 setfe are very small and difficult to detect, and are shown too 

 distinctly in Beddard's figure ; also, the lateral setfe are much 

 nearer to the ventral ones than indicated in the figure. 



The papilla of the hind groups are smaller than the large 

 ones of the fore group. They constantly begin at the twenty- 

 third segment, forming a continuous longitudinal series ;it 

 each side. At the most there are five pairs on segments 

 23-27 ; the smallest number, found only on one specimen and 

 on one side, was two papillae on segments 23-24. There are 

 never less than six papilla? in both series taken together. 



Spermathecal pores : in the specimens on which I 

 founded my M . z u 1 u the spermathecal pores formed groups 

 of 1-10 at each side on the furrows betAveen segments 11-12 

 or 12-13 to 15-16. In one of the two recently examined 

 mature specimens I could not see spermathecfe, just as 

 Beddard failed to find them ; but in a second mature speci- 

 men, after having torn away all septa, I discovered a few 

 very small globuhir spermatheca?. They were, however, very 

 much fewer than in the original type-specimens. 



Male pores : I could not detect the male pores in any
