DESCRIPTIONS OF GENERA AND SPECIES 587 



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

 interval. 



Subfamily Pabeudeiiinab. 



Definitiom-. Integumental sense organs rarely present i. Sperm-ducts without 

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

 modified or absent. 



Genus Eudriloides, Michaelsen. 



Definitiobt. Setae strictly paired. Spermatheeal pore on XIII or XIIl/XIV. 

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

 sac. Fenial 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 

 spermatheeal 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 papiUae. 



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 spermatheeal 

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

 in the presence of the peculiarly modified caleiferous glands. 



(i) Eudriloides gypsatus, Michaelsen. 

 B. gypsatus, Michaelsen, JB, Hamb. wiss. Anst., vii, 1890, p. 23. 



Definition. Length, i^o mm.; breadth, ^^ mm.; number of segments, 147. Clitellum, 

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

 without glands. Penial setae bent into a hook at free extremity without denticulations. 

 Hab. — Zanzibar and Kikota ; E. Africa.
