DESCRIPTIONS OF GENERA AND SPECIES 603 



There are two pair of testes and funnels ; the latter do not lead into a dilated 

 part of the sperm-duct as in many Eudrilids. The spermiducal glands open by a 

 common orifice through which protrude a pair of penial setae. Connected with the 

 penis is a muscular sac opening on to one side of it, and terminating blindly in the 

 body-cavity. 



I have already dealt with the peculiar calciferous glands of this species. The 

 gizzard lies in v; septa v/xii are thickened. 



Stuhlmannia variabilis, Miohaelsen. 

 S. variabilis, Miohaelsen, JB. Hamb. wiss. Anst., vii, 1890, p. 2,4. 

 Definition. Length, 125 mm.; diameter, % mm.; number of segments, 175. Setae show 

 traces of ornamentation. Penial setae grooved at free extremity tvith serrated margins. 

 Hah. — Korogwe, KiJiengo, Mombasa, Zanzibar. 



This species was at first (12) briefly, and then more fully (6) characterized by 

 Miohaelsen with illustrations. I have myself examined a large number of specimens, 

 both living and preserved. The living worms are extraordinarily thin and apparently 

 tough ; during life their length is very considerably greater than after preservation. 

 The above dimensions are considerably in excess of those which I noted in preserved 

 examples, but Miohaelsen states that he had sexual specimens not half the length. 

 The setae often showed a yellowish-brown coloration at the extremity and faint 

 transverse ridges. I received this species from bogs on the African coast, where 

 they were collected for me by Mr. Finn. 



Sub-Family Eudeilini. 



DEPlNlTlOlir. Integumental sense organs present. Calciferous glands paired, and 

 unpaired of the usual structure. No integumental nephridial network; sperm- 

 ducts with dilatation immediately following funnel. 



Genus Eudbiltjs, Peerieb. 



DEFiiiriTioiir. Setae paired. Male pores paired on XVII. Spermathecal pores 

 paired on XIV. Two median calciferous pouches in X, XI. Paired calciferous 

 glands in XII. Oviducts open into the spermathecal sac of their own side, 

 the latter has an appendix of a glandular nature (?). Each spermiducal gland 

 is divided by a longitudinal septum into two halves. No penial setae.
