Clitellum complete in one specimen ; slightly developed and 

 recognisable in two others ; absent in all the rest ; comprises five 

 complete segments xiv to xviii, and in addition takes in small 

 portions of xiii and xix ; as the male pores are on xviii the species 

 is therefore intraclitellian. 



Male pores on two prominent papillae about 5 mm. apart, in 

 line with about the 5th or 6th rows of setfe, or with the interval 

 between them ; setae not visible on the ventral surface between 

 the pores. Oviduct pores two, in the interval devoid of setpe, on 

 segment xiv, close together, just in front of the line of setse. 

 Spermathecal pores three pairs, between segments vi and vii, vii 

 and VIII, and viii and ix, about in line with the 5th row of setce. 



Dorsal pores after segment v. Nephridiopores not discernible. 



No trace of any accessory copulatory structures. 



The alimentary canal comprises a buccal mass and muscular 

 pharynx with its strong pharyngeal muscles occupying the first 

 four segments, a long piece of cesophagus several times bent on 

 itself, of which a short anterior portion is in v, and a much longer 

 piece with the large gizzard in vi, the latter having immediately 

 behind it the posterior mesentery of this segment, but pushing 

 back it and the next two or three succeeding mesenteries which 

 thus — in a contracted worm — come to lie close to each other, and 

 causing a considerable displacement in these segments; in segments 

 IX to XV the small intestine presents calciferous glands, the portions 

 in these segments being very vascular, globularly dilated, inter- 

 nally shewing ridges, but distinct pouches are not pinched off ; 

 the portion in xvi is narrow, while in xvii the large intestine 

 suddenly commences ; this is without cseca, and being coiled in 

 cork-screw fashion its apparent calibre is greater than it really is. 



The first noticeable mesentery, thin and incomplete, is that 

 between iv and v ; from about viii to xvi the mesentai'ies are 

 somewhat thicker than elsewhere. 



Genitalia : two pairs of testes in xi and xii, small white bodies 

 (2*5 mm. long, and about 1 mm. wide in a specimen 12*5 cm.
