three other processes and a membranous expansion on the posterior 

 aspect of the appendage. Lengtii up to 13 millim., 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. 



Strongylosoma guerinii, Gerv. Ann. Soc. Ent. Fr. iv. p. 686. 



Hammam R'irha. 



This species was originally described from Madeira, whence the 

 British Museum has examples. It is widely distributed in the 

 Atlantic Islands, occurring both in TeneriflFe and the Bermudas. 



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

Hammam R'irha. 



This interesting MiUipede is a great rarity. It has been found in 

 Italy, but is new to the African shore of the Mediterranean. The 

 repugnatorial pores begin on the fifth somite.

As nothing appears to be known of the Earthworms of the 

 northern part of the African Continent, excepting Egy))t, I am very 

 glad to have had the opportunity, afforded me by Dr. Anderson's 

 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 those of Europe. 

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