The following pages include a note on every species belonging to the Cteniform Spiders which have been described from Africa and Western Asia, besides descriptions of eight new species of the two-clawed form and four of the three-clawed form. On page 351 ' of my paper on the Ctenido' of Burmah I expressed myself as " satisfied that one cannot restore Thorell's genus Dolopceiis for the Eastern Asiatic forms" of the three-clawed specimens. Since this was written, however, more material has come to hand, which enables me to reverse my decision in this respect. The following list contains the names of the new species described : — Ctemis johnstoni, sp. n. Zomba, Lake Nyassa. Hngsleyi, sp. n. Cameroons, W. Africa. occidentalis, sp. n. W. Africa. spenceri, sp. n. E. London, S. Africa. carsoni, sp. n. Tanganyika, &c. burtoni, sp. n. Cameroons, W. Africa. marshalli, sp. n. Umfuli Eiver, S. Africa. corniger, sp. n. ISTatal, S. Africa.
