DESCRIPTIONS OF GENERA AND SPECIES 587 



are the Geoscolicidae ; but I admit that they are separated by a considerable 

 interval. 



SUBFAMILY PAREUDRILINAE. 



DEFINITION. Integumental sense organs rarely present : . Sperm-ducts without 

 dilatation ; duets of nephridia branching in body -walls ; calciferous glands 

 modified or absent. 



Genus EUDBILOIDES, MICHAELSEN. 



DEFINITION. Setae strictly paired. Spermathecal pore on XIII or XIII/XIV. 

 Male pore on XVII/XVIII. Ovaries independent of oviducts and spermathecal 

 sac. Penial setae present. 



This genus is undoubtedly, as MICHAELSEN has pointed out, at the base of the 

 series ; the ovaries retain their primitive distinctness and are not in any way bound 

 up with the rest of the female generative apparatus. The position of the median 

 spermathecal sac and the characters of the spermiducal glands alone serve to indicate 

 that the genus is to be referred to the family Eudrilidae. 



The genus contains five species, all of which are East African in habitat. They 

 are to be distinguished by the shape of the penial setae and by the genital papillae. 



It is, perhaps, a little doubtful whether the two species, E. cotterilli and 

 E. brunneus, are to be referred to the same genus as the three first. They differ in 

 the absence of the dorsal pores (a most unusual character in the family Eudrilidae, 

 and only found elsewhere in Platydrilus lewaensis), which occur in the three species 

 described by MICHAELSEN : in the presence of glandular appendices to the spermathecal 

 sac, like those of Notykus: finally, they differ, perhaps (see, however, under E. titanotus), 

 in the presence of the peculiarly modified calciferous glands. 



(i) Eudriloides gypsatus, MICHAELSEN. 

 E. gypsatus, MICHAELSEN, JB. Hamb. wiss. Anst., vii, 1890, p. 23. 



Definition. Length, 130 mm.; breadth, 3^ mm.; number of segments, 147. Clitellum, 

 XIV-XVII. Dorsal pores present from IX/X (?). Spermathecal sac opens on XIII, 

 without gla.uh. Penial setae bent into a hook at free extremity without denticulationi. 

 Hab. Zanzibar and Kikota ; E. Africa.
