Besides the new species, No. 20—21, Angara Jenta and A. 

 obtusa, which I wish on this occasion to describe because my 

 earlier description of the first species made after very bad mates] 

 rial is not sufficient and the other is hitherto unknown, the Expel 

 dition has brought back specimens of two species No. 25 & No.: 

 26, Periscyphis convexus and P. albescens, each of which have 

 previously occurred in a single specimen, and I have made use 

 of this material in combination with materials from other parts 

 to give a new description over the characters for the genus 

 Periscyphis. 



The Egyptian Fauna of Terrestrial Isojoods is entirely Medi- 

 terranean, all the species below mentioned have their nearest 

 allies in South Europe, N. Africa and Asia Minor, only the two 

 species of Periscyphis are typical African, and all the other species; 

 of this genus, as I have here limited it, are found in the middle 

 of Africa. 



Familia: Oniscidae. 



Genus: Armadillo.

 cies is very widely distributed over all the countries round about 

 the Mediterranean Sea, and seems to be very abundant in many 

 localities. 



2. Armadillo sodalis.

 species in the Museum at Berlin. 



Genus: Armadillidium. 



3. Armadillidium decorum.
