3504 MR. R. I, POCOCK ON THE [ Apr. 21, 
Aviculariine is represented in the Mediterranean area by the 
primitive genus [schnocolus, which ranges from Spain and Algeria 
to Syria, and perhaps also occurs in Burma; by Chetopelma and 
Cratorrhagus, which ave perhaps identical, found in the eastern 
countries of this sea; in India by the genera Phlogiodes, Plesio- 
phrictus, and Heterophrictus; and in tropical West Africa by 
Scodra, Heteroscodra, Selenogyrus, Heterothele, and Solenothele. 
In America the group is represented by a wealth of genera 
ranging from the Southern States of the Union (Sonoran), 
throughout the West Indies and over the whole of 8. America to 
Chili and the Argentine. It is necessary to mention only a few 
of the principal genera, such as Aphonopelma from the Sonoran, 
Brachypelma, Cyrtopholis, Hapalopus, Acanthoscurria, Lasiodora, 
Pamphobeteus, Avicularia, Tapinauchenius, Citharoscelus, Metrio- 
pelma, Theraphosia, &e. &e. 
The Selenocosmiine range from India and Ceylon over the 
Indo- and Austro-Malayan Islands and Australia; the principal 
genera being Pecilotheria, confined to India and Ceylon; Chilo- 
brachys, occurring in India, Ceylon, and Burma; Lyrognathus in 
Assam; Selenocosmia, extending from the Himalayas into 
Australia; and Selenotypus and Selenotholus, which are confined 
to Australia. 
The Thrigmopceine, represented by Thrigmopeus and Haplo- 
clastus, are confined to 8. India. 
The Ornithoctonine—Cyriopagopus, Melopweus, Ornithoctonus, 
Phormingochilus, Citharognathus—extend from Burma to the 
Moluccas. 
The Eumenophorine, containing the genera Humenophorus from 
Sierra Leone, Hysterocrates from the Congo, &c., Phoneyusa and 
Pelinobius from the Congo and Masailand, Batesiella from the 
Camavroons, Citharischius and Anoploscelus from British East Africa, 
Monocentropus from Sokotra and 8. Arabia, and Hneyocrates from 
Madagascar, are thus restricted to Madagascar and the northern 
portions of the Ethiopian Region, since they do not appear to 
pass south of the Congo or the Zambesi. 
The Harpactirine, on the contrary, are confined to South and 
East Africa, ranging from Masailand to Cape Colony, and crossing 
the area of the Eumenophorine north of the Zambesi. The 
principal genera are Pterinochilus, Hucratoscelus, Ceratogyrus, 
Celogeniwm, Harpactirella, and Harpactira. 
Of the above-mentioned subfamilies the least specialised is that 
of the Aviculariine, which contains genera like Heterothele and 
Mitothele, serving to link in a measure the Aviculariide with the 
Macrotheline Dipluride. It is, moreover, the most widely 
distributed and most northerly in its range of all the sub- 
families, and far the richest and most diversified in its genera. 
Certain facts point to the conclusion that the Selenocosmiins 
originated in South-eastern Asia. The two most primitive 
genera of the subfamily, Phlogiellus and Selenocosmia, occur at the
