I have but little doubt that this is the male of Ger- 
staecker’s species. The typical carina ending in a spatulate 
tooth is a very characteristic feature of the Oriental genera 
Perisphaeria and Pseudoglomeris and the male of oniscina is also in 
general appearance very like males of Pseudoglomeris species from 
Burma, Borneo, Java etc. The female of oniscina differs from 
females of Oriental species of Perisphaeria and Pseudoglomeris in 
the total absence of a tooth to the pronotal carinae beneath, 
but otherwise is very similar; it is convex and possesses the 
power of rolling itself up into a ball like a Millipede or ter- 
restrial Isopod and like the Oriental Perisphaeriinae of the female 
sex. On account of the division of the abdominal tergites into 
two zones separated by a sulcus, oniscina falls into the genus 
Pseudoglomeris and not into the genus Perisphaeria. The genus is 
new to the Ethiopian fauna.
