Show 740 MR. R. 1. POCOCK ON ETHIOPIAN SPIDERS. [Juue 15, (? 1 at base of protarsal scopula); 2nd leg with one spine at base and another at apex of protarsal scopula ; tibia and protarsus of 2nd and 3rd strongly spined, especially in front; the patellae thickly studded with spiniform setae ; spinuliform hairs on the anterior aspect of the base of the coxae, especially of the 1st and 2nd legs; tibia of palp spined beneath, its tarsal scopula divided. Abdomen rather coarsely and sparsely hairy. Measurements in millimetres. Total length 14 ; length of carapace 5-5, width 4-5 ; length of palp 9, of 1st leg 13-5, of 2nd 12-3, of 3rd 11-2, of 4th 17*5. Loc. Somaliland (Dr. Donaldson Smith). A single female example, intermixed with immature and unidentified examples of a species of Pterlnochllus. Genus BRACHIONOPUS, nov. Somewhat allied to the preceding, with substantially the same ocular arrangement, but the tubercle situated some little distance from the anterior border of the carapace, the clypeus thus constituted being about equal to half the length of the tubercle. The sternal sigilla are situated as in Euhrachycercus, and the labium is only furnished with a few minute granules ; the adjacent area on the maxilla being also sparsely granular. Legs short and robust; the scopulae are not broader than the segments, and the tarsal scopula of the palp and of the 1st leg are entire, those of the 2nd and 3rd just visibly divided, that of the 4th more distinctly so ; the protarsal scopulae of 3rd and 4th, though not very thick, extend past the middle of the segment; there are spines on the legs and the ungual tufts are exceedingly thick, completely concealing the two claws, which are not toothed. On the mandible there is a scarcely perceptible rastellum; some of tbe hairs being merely thickened and spiniform. The basal segment of the posterior spinners is about as long as the other two, and the second is a little longer than the conical apical segment. BRACHIONOPUS ROBUSTUS, sp. n. (Plate XLII. fig. 4.) Colour. Carapace and abdomen covered with golden brown hairs; mottled on the abdomen, especially at the sides and below, with blackish; small spots of brighter coloured hairs on the tibiae and protarsi of the legs, and narrow bands of light coloured hairs at the extremities of the segments. Carapace oval, cephalic area but little elevated, narrow; about as long as the patella, tibia, and protarsus of the 1st leg, and as the patella, tibia, and half the protarsus of the 4th ; longer than the tarsus and protarsus of the 4th. Legs short and robust; 4, 1, 2, 3 ; patella and tibia of 1st about equal to those of 2nd; patella of 1st longer than the tibia, much longer than the protarsus; patella of 4th equal to its tibia, shorter than its protarsus ; palp without spines; 1st and 2nd legs with a single spine at the apex of the protarsus beneath ; tibia of 3rd armed with two spines below and one in front, protarsus with one |
