Show 1897.] MR. R I. POCOCK ON ETHIOPIAN SPIDERS. 763 width of the tubercle or of the labium. Labium almost as long as wide, densely spinulose. Mandibles robust, the curvature of the upper and anterior surface studded amidst the hairs with a number of smooth round jet-black granules ; the lower half of the outer surface almost naked, the inferior margin granular behind and armed internally with 11 blunt teeth. Legs longish, robust, 4, 1, 2, 3; the 4th exceeding the 1st by a little less than the length of its tarsus ; patella and tibia of 4th only slightly longer than of the 1st (26 mm.: 25-3) ; the patellae of the two about equal, but the femur, tibia, and protarsus of the 4th respectively longer ; the 4th leg also stouter than the 1st, its femur, patella, and tibia being noticeably thicker, the distal end of its femur a little wider than the patella, which is also wider than the tibia, the width of the patella less than half its length and about equal to its height, the width and height of the tibia about equal and just about one-third of its length, the protarsus distinctly although not very much longer than the tibia (17*5 and 15*5 mm.). The legs unarmed except for a few spines at the apices of the protarsi ; the setae on the legs are few in number and not long ; there is a curious brush of hairs on the upperside of the coxa and trochanter of the 1st and 2nd legs. Palp reaching almost to the apex of the tibia of the 1st leg; the area on the inner surface of the maxilla lying between the suture and the oral fringe normally hairy, the whole appendage unarmed; tibia and tarsus about equal in length, the tarsus longer than that of the other appendages. Abdomen elongate, oval. Posterior spinner equal to length of 3rd protarsus. 3. Carapace broader and flatter than in the $; legs longer; mandibles smaller but more noticeably tubercular; patella and tibia of 1st leg longer than of 4th; the legs also considerably more bristly than in the 5 , especially on the posterior tarsi and protarsi, the posterior tibiae also relatively thicker. Length of carapace equal to that of tibia 4-protarsus of 3rd leg and only slightly excelling tarsus and protarsus of 2nd ; its width equalling femur of 4th; in 2 length of carapace almost equals that of tibia, protarsus, and tarsus of 3rd leg, and tarsus and protarsus 4- three-quarters of the tibia of the 2nd. Palp as in the following species, H. crasslpes, except that the spine of the organ lies a little nearer the bulb and the triangular tooth is a little more prominent.
