1. Further notes upon the reproductive organs of Eudrilus. 



By F. E. Beddard, London. 



eingeg. 6. October 1888. 



The investigations of Per rie r^, Horst^ and myself ^ have shown 

 that the reproductive organs of Eudrihis present certain noteworthy 

 differences from those of other genera of OUgochaeta. 



Of the male organs the testes and vesiculae séminales are perfectly 

 normal ; but the efferent ducts and the terminal apparatus are, in many 

 points, unlike those of any other earthworm, excepting only the genus 

 Teleudrilus recently described by Rosa*. The female organs are chiefly 

 remarkable on account of the continuity of the ovary and oviduct, and 

 the communication between the oviduct and the spermatheca. Teleu- 

 drilus is somewhat intermediate in these particulars between Eudrilus 

 and other earthworms ; the discovery of this genus, as Dr. Rosa points 

 out, renders less necessary the separation of Eudrihis into a distinct 

 group. At the same time I do not think that Dr. R o s a is inclined to 

 lay sufficient stress upon some of the peculiarities in the organisation 

 of these two types ; and I cannot agree with the way in which he has 

 interpreted some of my own statements of fact. 



With regard to the female generative apparatus the differences 

 between Eudrilus and Teleudrilus are greater than would appear from
