Madagascar shows no similarity to the Oriental Region, with which 
Simon united it. (Trouessait, La Géogr. Zoolos. pp. 208-211, 
1890.) 
The African portion of the Ethiopian Region is divisible into 
two well-marked subregions, namely, the West-African or forest 
area of the Congo, which extends from the shores of the Gulf of 
Guinea to Uganda, and a South and Hast-African area. The 
former is essentially characterised by the presence of the Avicu- 
lariine, Kumenophorine, and Barychelide; the latter by the 
Har pactiri ine, Cyrtaucheniide, and Migide. In East Africa, 
north of the Zambesi, the two regions cross.

1 New name for the species from Tenasserim, described by Thorell as Ischnocolus 
brevipes (Thorell, Ann. Mus. Genova, xxxvii. p. 170, 1897; also Pocock, ‘ Fauna of 
British India: Arachnida,’ p. 183), which at least differs from the typical species of 
Ischnocolus from the Mediterranean in having the tarsus of the palp short in the male,
