distinct ; there is no median dorsal row of setae, and apparently 

 there is a narrow dorsal break, but as the specimens are small and 

 contracted it is difficult to be quite sure. Male pores two, each on 

 a prominent papilla on xviii, the ventral portion between the 

 papillae slightly swollen forming a slight ridge across the interval, 

 on which ventrad of each papilla two or three setae are visible. 

 Oviducal pores not visible. Spermathecal pores three pairs, 

 between iv and v, v and vi, vi and vn, about corresponding with 

 the intervals between the fourth and fifth rows of setae on each 

 side. Dorsal pores after about iv. No indications of accessory 

 copulatory organs in any of the specimens. 



The pharynx occupies three or four segments ; the oesophagus is 

 rather long ; the gizzard is in vn, or at least has immediately 

 behind it the posterior mesentery of this segment, but in front of 

 it the mesenteries were thin and apparently incomplete and difficult 

 to make out ; it pushes backwards several of the mesenteries behind 

 it ; the small intestine occupies segments vm to xvi, is unprovided 

 with diverticula, but in x to xiv, the intermesenteric portions are 

 dilated, especially in xi to xin ; the large intestine commences in 

 xvi, no caeca in xxvi. 



There are two pairs of racemose testes in xi and xn, attached to 

 the anterior mesenteries quite independently of each other ; two 

 pairs of ciliated rosettes in x and xi, the posterior portions of the 

 vasa deferentia were not discernible ; in xviii a pair of prostates 

 their proximal portions long, narrow, continuous with the genital 

 ducts, looking more like convoluted thick-walled tubes than solid 

 glands, their distal portions a little more compact. The ovaries 

 and oviducts have the usual situation and relations ; the external 

 apertures of the latter were not visible ; there are three pairs of 

 small spermathecae, the posterior pair the largest, the anterior pair 

 the smallest, apparently in segments v, vi, and vn ; each of them 

 pear-shaped, very shortly stalked, and with a long filiform caecum 

 slightly longer than the main sac. 



The lower and lateral portions of segments xand xiwere filled with 

 white masses of spermatozoa, but whether they were lying free, or 

 enclosed with the ciliated rosettes within a membranous sac or
