604 OLIGOCHAETA 



This is one of the few genera of extra European Terricolae which has quite 

 a long history. It is one of the types described by PERKIER in his classical paper 

 upon the classification of the Oligochaeta (3). PERRIER there described three species, 

 the validity of which will be considered later. The next contribution to the structure 

 of the genus was by myself, and dealt with the peculiar features of the female 

 reproductive organs (14). In two subsequent papers I described two ' species ' of 

 Eudrilus, the one from New Caledonia (4), the other from British Guiana (62). 

 A little later HORST (2) made some remarks upon specimens of Eudrilus from New 

 Caledonia and Surinam. The two most recent contributions to the structure of this 

 genus are a paper by HORST (8) upon the anatomy of a species of the genus from 

 Liberia, and a description by MICHAELSEN (10) of two species, really distinct, from the 

 coast of West Africa. 



The present genus is remarkable for its extremely wide distribution. There are 

 very few terrestrial Oligochaeta excepting those belonging to the genera Lumbricus 

 and Allolobophora, which are more widely distributed ; but there are not many 

 quarters of the globe which have not been shown to harbour the genus Eudrilus. 

 It is found in the West Indies, in South America, in West Africa and St. Helena, 

 in Ceylon, in New Caledonia, and in New Zealand. A more detailed account of 

 its distribution will be found under the description of the species. Of species the 

 following have been described : 



E. lacazii, PERRIER, Martinique. 



E. peregrinus, PERRIER, Rio Janeiro. 



E. decipiens, PERRIER, West Indies. 



E. boyeri, BEDDARD, New Caledonia. 



E. sylvicola, BEDDARD, British Guiana. 



E. jullieni, HORST, Liberia. 



E. pallidus, MICHAELSEN, Accra, West Africa. 



E. buttneri, MICHAELSEN, Togo, West Africa. 



E. roseus, MICHAELSEN, Venezuela. 



E. erudiens, UDE, Bermudas.
