three other processes and a membranous expansion on the posterior 

 aspect of the appendage. Length np to 13 miUim., width 1*6. 



Closely allied to, if not identical with, B. proximus of Latzel from 

 the Azores. 



Hammam R'irha. 



This is probably the species that Lucas records as Polydesmus 

 complunatus. 



Strongylosoma guerinii, Gerv.

 Atlantic Islands, occurring both in Teneriffe and the Bermudas. 



I suspect that this is the species which Lucas identified as S,

As nothing appears to be known of the Earthworms of the 

 northern part of the African Continent, excepting Egypt, I am very

 kindness, of examining a small collection made by him during the 

 spring of last year in Algeria and Tunisia. 



Earthworms show in so very plain a manner the effect of barriers 

 to dispersal in their distribution, that I had expected to find the 

 Algerian forms identical with or closely allied to tliose of Europe. 

 The Earthworm-fauna of Central and South Africa is evidently very
