 Expedition to West Africa, 1889 and 1890.

The west coast of Africa is very vicli in species of Myriapoda, 

 notably Polydesmidte and Julidie. Spirostreptus is to be con- 

 sideved the characteristic genus, of which more than a hundred 

 species have ah"ead\^ been described from different parts of Africa. 

 The Cape of Good Hope has furnished a majority of these; the 

 only other locality which has received anything like a thorough 

 investigation is Benguela, the species of which are described by 

 Porath in "Myriapoda Africse Australis." The considerable num- 

 ber of species from other localities is the result of casual collection 

 by persons not specially interested in the group, and so the subject 

 is in a fragmentary condition. It is a matter of some regret to us 

 to make an addition to this scattered literature, but there seems to 

 be no other course. The species here noticed were collected at 

 points remote from each other, ranging all the way from Senegam- 

 bia to Cape Town. We have attempted to make our descriptions 

 and figures sufficiently complete and definite to insure the recogni- 

 tion of the species if found again. 



When Dr. Riley sent us the material for study it was the inten- 

 tion of the government authorities to publish at one time the com- 

 plete scientific results of the expedition ; but as this seemed likely to 

 be indefinitely deferred, it was thought best to offer this paper else- 

 where. The materials on which it is based are in the collection of 

 the National Museum at Washinerton.
