distance between the setae of the lateral pairs, a little larger than that betvs/een the setse 

 of the ventral pairs {aa > bc=cd >ab ; aa =ca. i^ab) . 



First dorsal pore in the intersegmental furrow lo-ii. 



Clitellum more or less distinctly ring-shaped, ventrally less prominent or in 

 parts apparently not particularly glandular, occupying segments 13 — 17 ( =5). 



Male pores on the 17th segment, on thick, transversely oval, prominent papillae, 

 the centres of which are situated a little lateral from the lines of setae b, much nearer 

 to these than to the lines of setae c. 



Female pores on the 14th segment just before the setae a, surrounded by a not 

 sharply bordered whitish area, nearly confluent in the ventral median line. 



Spermathecal pores one pair, distinct, eye-shaped, on the intersegmental 

 furrow 7-8, their centres in the lines of setae c. 



Copulatory organs apparently always present, only slightly 

 variable in number and position. They are paired, transversely 

 oval intersegmental cushions, which transgress the lines of setae a 

 ventral-medially and those of setae b more or less laterally. The most 

 constant is a pair of such organs at the intersegmental furrow 

 15-16 (all seven specimens) ; in two specimens there is on one side 

 an unpaired additional one at 14-15. In five specimens there are 

 postclitellar cushions at 19-20 and 20-21, in one of these specimens 

 an additional unpaired one on one side at 21-22. In one specimen 

 the latter are dislocated for the length of one segment, being 

 situated on the intersegmental furrows 18-19 ^.nd 19-20. The 

 last specimen possessed only one pair of postclitellar cushions on 

 18-19. 



Internal Anatomy. — Septa 5-6 and 8-9 very thick, the inter- 

 mediate ones being apparently missing, or else very tender or 

 rudimentary, 9-10 and lo-ii somewhat thickened, the following tender. 



Alimentary tract: A big, oblique gizzard between the two strengthened 

 septa 5-6 and 8-9. In the 12th segment the oesophagus is thickened, globular, and 

 contains a pair of big calciferous glands of the shape of a pair of coffee-berries which 

 are not, however, visible externally. Intestine with a big typhlosole which is triangu- 

 lar in a transverse section and has a broad base and a moderately sharp edge. 



Nephridial system micronephric. 



Anterior male organs: One pair of large sperm-duct-funnels in the nth seg- 

 ment, enclosed in a common seminal vesicle which seems to embrace the oesophagus 

 in a ring-like manner. One pair of large, lobed sperm-sacs depending from septum 

 1 1- 1 2 into the 12th segment. 



Prostates very long, tube-like ; glandular part convoluted, occupying about 

 six segments (about 17—22). Muscular duct abruptly set off from the glandular part, 

 describing some large irregular loops, much thinner and very much shorter than the 

 glandrdar part, but nevertheless having a length of about 20 mm.
