The collections brought back by the expedition of Professor Yngve Sjöstedt from 

 East-Africa contained eighten species (621 ex.) of terrestrial Isopods. Sixteen of these 

 species were collected at the mountain of KiUmandjaro and at its environs, one species 

 was taken at Mombo and one at Tanga. Thirteen species were new, four hitherto only 

 known from East-Africa, one species is cosmopolite. 



Besides these thirteen new species, I know a large number of undescribed species 

 of terrestrial Isopods from East-Africa; it will, however, be away from the purpose for 

 this paper to describe all these species here, but it is always necessary when describing 

 the new forras to take into consideration the whole fauna of terrestrial Isopods known 

 from East-Africa; I have only taken up for description here a few species from other 

 collections known from the tract of Kilimandjaro. 



The greatest part of the terrestrial Isopods collected in Central-Africa belong to 

 types of genera, which are peculiar to this continent. 



Oniscidae. 



Subfamilia: Euhelinae. 

 In 1899 I have published a paper ^ containing descriptions of 22 species belonging 

 to this subfamily, more recently I have added one species^, and in 1907 H. Richardson 

 described 12 new species l Of these 35 species only four were known out of Africa,
