398 WILHELM MICHAELSEN. 



Collett, of the Christiania Museum, Dr. Jagerskiold, of the 

 Grotenborg Museum, and Prof. H. Theel, of the Riks Museum 

 of Stockholm, who have been so good as to allow me to i-e- 

 examine the types of certain formerl}^ described species of 

 olio-ochffites from Natal and Zululand. 



HISTOEY AND BIBLIOGEAPHY. 



Our knowledge of the earthworms from Natal and Zululand 

 extends back to the year 1866, when J. G. H. Kinberg pre- 

 sented to the Academy of Sciences at Stockholm a preliminary 

 paper on the " Oligochasta of the Eugenie Expedition. '' This 

 paper, as well as a few others published in the nineteenth 

 century, give only scanty information with reference to the 

 oligochaites of Natal. In the present century only two 

 papers dealing with the earthworms of the districts now being 

 considered have been published. These papers, however, are 

 far from giving an even fairly adequate picture of the oligo- 

 chaete fauna, since the larger of them deals with only six 

 different species. 



In the following list of papers there is given all the literature 

 up to the present which contains descriptions or revisions of 

 the Oligochasta of Natal and Zululand. To the titles of these 

 papers I have added the names of the species described, while 

 the modern synonyms are given in square brackets.
