Show 1897.] MR. R. I. POCOCK ON ETHIOPIAN SPIDERS. 733 dentate. They differ strikingly from the genera known tome; while Ancylotrypa is said to differ from Aporoptychus in having the .labium as wide as long (in Aporoptychus it is much longer than broad) and the posterior tarsus spined. Cyrtauclienlus and Homostola belong to the Cyrtauchenieae, which differ from the Ctenizeae in having the anterior legs scopulate and no angular prolongation for the rastellum on the mandible. Cyrtau-chenlus has the posterior line of eyes wider than the anterior, and the latter strongly procurved; in Homostola, on the contrary, the two ocular lines are subequal, the first not strongly procurved, &c. The remaining two genera, namely Hermacha and Splroctenus, fall into the Nemesieae, which differ from the Cyrtaucheneae in having the head lower and the thoracic fovea transverse or recurved. In Hermacha the claws are furnished with two series of teeth ; while in Splroctenus there is but one. Family MI&IDA = Mlglnce, Simon, Hist. Nat. Araignees, i. p. 82 (1892).

Of this species the British Museum has one example from Uitenhage, near Port Elizabeth, whence the original specimens were obtained. MOGGRIDGEA ABRAHAMI, Cambr. Moggridgea abrahami, Cambridge, Proc. Zool. Soc. 1889, p. 44, pl. ii. (published in April). Moggridgea tidmarshl, Lenz, Zool. Anz. xii. p. 578, 1889 (published on Nov. 4). The British Museum has specimens of this species from Grahams-town, whence they were received together with their nests from the Eev. N. Abraham, who originally forwarded examples of this species to Mr. Cambridge. The typical examples^ of tidmarshl were from the same locality, and since the description of the two forms agree, there is no reason for supposing them to be distinct. Mons. Simon placed this species in the genus Migas, the type of which comes from New Zealand; but as 1 have elsewhere (Ann. Mag. Nat. Hist. (6) xvi. p. 187) stated, I can see no valid reason for regarding it as other than a well marked species of Moggridgea. MOGGRIDGEA WHYTEI, sp. n. (Plate XLII. figs. 1-1 b.)
