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 East-African area. The former is essentially characterised by the presence of the Avicu-lariinse, Eumenophorinse, and Barychelidae; the latter by the Harpactirinae, Cyrtaucheniidae, and Migidae. In East Africa, north of the Zambesi, the two regions cross. Oriental Region. Dipluridae. Macrothelinae.-Macrothele : Burma, Malacca, Java. Ischno-thele: India. Atypidae.-Atypus: Burma, Java.

Genova, xxxvii. p. 170, 1897 ; also Pocock, ‘ Fauna of British India: Arachnida,' p. 183), which at least differs from the typical species of Ischnucolus from the Mediterranean in having the tarsus of the palp short in the male. |
