The above table includes 64 species^ and a glance at their distribution shows 

 as might have been safely predicted that the closest affinity of this Blattid fauna is 

 found in East Africa between the 5^'^ degree of latitude and the Zambezi River; 20 

 of the species are common to these two areas and I have little doubt that the 

 number would be increased if our knowledge of the cockroaches of the latter area 

 was greater than it is. 7 of the species are cosmopolitan or nearly so and consequently 

 afford no evidence worth taking into consideration. The relationship with the Abys- 

 sinian fauna is rather surprisingly remote, bnt can perhaps be accounted for by the 

 Intervention of the xerothermic area of Somaliland and Gallaland between the damp 

 moist regions of Abyssinia and Kilimandjaro ; it is significant that there is a muoh 

 closer relationship between the faunas of these two regions in the case of insects 

 capable of sustained flight such as the Lepidoptera Rhopalocera. Only 4 of the 

 species occur also in Africa south of the Zambesi and the entire absence from the 

 Kilimandjaro region of certain liighly characteristic South African genera is in sharp 

 contrast to the fact that all the Abyssinian genera save two° are represented in the 

 Kilimandjaro region. The connectioii with the West African and jNfascarene faunas
