sent nie among other Isopods by Dr. R. Gestro at Genoa. 

 Still later I have described two new species here belonging 

 procured by the Stuhlmann-Emin Pasha Expedition in East- 

 Afrika *). 



With these materials I have found it useful to take 

 up to renovated examination all the species, so much the more 

 as I mean, that I am able to refer here different species 

 described by different authors, although I have not seen them. 



On account of some relations particularly from the 

 structure of the antennae, the mouth and the first segment 

 of the trunk I have conceived, that other much deviating 

 characters, which by these animals to my present opinion 

 give good generic characters, are here of lower value, and I 

 have assembled in a new family or tribus animals although 

 differing somewhat from each other in habitus, are among 

 themselves closely related, and the extreme forms are so con- 

 nected by intermediate forms that they might be regarded as 

 forming a good limited group. The here enumerated 22 species, 

 among which are 12 new ones, are certainly but forerunners 

 for a swarm of forms, which the inner Africa shall bring to 

 light. It shall be proved, that the Etibelidce will have the 

 same systematic value as all the Armadillidte and Porcellio- 

 nida; taken together, and their terrestrial spreading is an 

 argument more for the justness of the zoogeographical zone, 

 Africa to the south of Sahara, and for an old union of this 

 continent with South-America.
