sent me 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 antenne, 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 Zubelid® will have the 
same systematic value as all the Armadillide and Porcellio- 
nide 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.

Antenne: Flagellum plerumque plus vel minus obscure 
triarticulatum, raro solum biarticulatum; scapi articulus 1 
brevissimus, articulus 3 semper brevior quam 2, articulus 4 
paulo longior quam 2, articulus 5 semper longissimus. 
Oculi manifesti, congregati. 
Caput: Epistoma lineam marginalem frontalem con- 
tinuam, in medio sepe deletam formans. Foramina anten-
