over the 17-20 segments. The ventral pairs of setae of the 25-27 

 segments placed upon transversely oval glandular papillae ; some of 

 the ventral pairs of setae in the fore-part of the clitellar region on 

 similar but more indistinct papillae. 



Spermathecal pores in groups of 2 to 6 at each side of the inter- 

 segmental furrows 12/13-16/17, in the lines of the nephridial pores, 

 and dorsally from them. 



Inlrrnal Anatomy. Septa 4/5, 5/6, and 6/7 very strongly thickened, 

 7/8 and 8/9 moderately thickened, the following tender, and only 

 9/10 a little thicker than the very tender ones which follow it. 



Alimentary tract : A large gizzard in the 7 segment. A large, 

 nearly globular swelling of the oesophagus apparently restricted to 

 the 10 segment represents the calciferous gland. 



Male organs : Two pairs of spermiducal funnels in the 10 and 11 

 segments, each pair enclosed in an unpaired transverse seminal 

 vesicle ; each of the latter is laterally continued into a sperrnsac-like 

 appendix. Two pairs of sperm-sacs in the 11 and 12 segments com- 

 municate with these appendices of the seminal vesicles. 



Spermathecae pear-shaped, shortly and narrowly stalked. 



Glands of sexual setae 16 pairs in the 12-17 segments. The 

 glands have the shape of a slightly bent thick sausage, opening 

 through a narrow and rather short duct.
