Vesicle smooth above, thickly hirsute aud weakly granular below ; subaculear spine small and blunt. Palpi setose, especially on the fingers: humerus marked above with the customary anterior and posterior granular keel ; anterior surface bearing larger and smaller granules: brachium furnished in front with a few tubercles, the rest of the segment smooth and rounded, without keels or granules: manus smooth and rounded, slightly wider than the brachium, neither keeled nor granular and not armed with a tooth : dactyli short and curved, in contact throughout, being neither lobate nor sinuate ; denticles arranged as in the preceding species. Legs hirsute, but almost wholly smooth; tibice of the two posterior pairs spurred. Pectines armed with 17 approximately similar teeth ; the basal tooth being only slightly thicker and slightly shorter than the rest. Stigmata small and slit-like. Measurements in millimetres.-Total length 28'5 ; cephalothorax length 4*2, width 4 : length of tail 17; of first two segments 4 ; of fifth segment 3"5 ; of vesicle and aculeus 3-8 ; width of first segment 2-5, of fifth 2*3 ; humerus length 3 ; brachium length 3-7, width 1*5; width of manus 1*7 ; length of ' hand-back ' 2, of movable dactylus 32. Two specimens (?) from Natal; one presented by Ernest Howlett, Esq., the other from the collection of Gueinzius. This species may be recognized by the wide, undivided, median, longitudinal, yellow band on the abdomen, by the wide black band on each side of it, by the absence of fuscous patches on the upper surface of the four first tail-segments, by its fuscous hands .and almost wholly ochraceous humerus and brachium. It differs, in addition, from U. triangulifer (Thor.) in being much smoother both above and below. UROPLECTES FLAVOVIRIDIS, Peters. (Plate XIV. fig. 5.) Monatsb. Ak. Wiss. Berlin, 1862, p. 516.
