The worms which form the subject of the following paper 

 were obtained in a living state from Kew Gardens, along with 

 a number of others whose structure I propose to investigate 

 later. 



I had applied to Mr. Thiselton Dyer for leave to sift soil 

 coming from tropical countries in the Wardian cases which 

 are generally used for transmitting plants in pots. This Mr, 

 Dyer very kindly permitted me to do, and in his absence Mr. 

 Morris was so good as to put me in the way of carrying out 

 my wishes. To both these gentlemen my thanks are tendered. 

 In the earth surrounding a number of pots containing plants 

 from Lagos, West Africa, I found about half a dozen worms, 

 which proved on examination to belong to the family 

 Eudrilidse. 



Until quite recently one genus — Eudrilus itself — was the 

 only known representative of the family ; three years ago Dr. 

 Rosa described from Scioa, Africa, another genus — Tel eu- 

 drilus; and quite recently Dr. Michaelsen has received from 

 Zanzibar and the mainland opposite, and from the mouth of the 

 Zambesi River, a number of species, all belonging to this family, 

 and referable to four new genera : the family is, therefore, in the 

 present state of our knowledge, characteristically Ethiopian,
