Claws furnished with a row of small teeth. External spinners about half the length of tbe carapace; the internal separated by a space which is nearly equal to their length. Tibia of 1st leg in male not spurred. MIASCHISTOPUS RAPIDUS, sp. n. (Plate XLI. fig. 5.) Colour. Carapace covered with yellowish-brown hairs, those on the legs browner and intermixed with blackish setae; coxa?, sternum, and lower surface of the femora greyer; a band of whitish hairs on tip of femora, patella, tibiae, and protarsi; abdomen covered below with brownish-yellow hairs; the upper surface naked behind, covered in front with long greyish or reddish erect setae rising out of a greyish coating of hairs. Carapace as long as patella and tibia of 3rd leg, excelling patella, tibia, and tarsus of palp, shorter than protarsus of 4th, but longer than the other protarsi by about half the length of their respective tarsi; width of carapace about equal to tibia of 4th, greater than the other tibiae. Legs. Patella and tibia of 4th a little excelling those of 1st and excelling the tarsi and protarsi of the 1st, 2nd, and 3rd pairs; patella, tibia, and tarsus of 3rd a little less than those of 1st, and just about equal to those of the 2nd ; 1st leg shorter than 4th by about the length of the tarsus, 3rd shorter than 1st by almost the same amount; femora of legs with an internal apical spine, patella of 3rd and 4th with an internal (posterior) spine ; tibiae of all the legs armed with many strong spines, with always a pair and sometimes more at the apex below; protarsi of 1st and 2nd spined beneath at the base and tip of the scopula, the 1st with only one at the base, the 2nd with 2 or 3 ; protarsi of 3rd and 4th very strongly spined both below and above ; tibia of 3rd thick, the width more than one-third of its length. Palp extending just past the patella of the 1st leg, its femur armed with an internal apical spine, its tibia with an internal distal cluster of about a dozen spines. Palpal organ prominent posteriorly at the base, the bulbous part passing without any constriction into the spine, which is exceeding broad basally, where it bears a distinct posterior nodular prominence, and when viewed from the side is triangular, pointed below, tbe apex being in no sense filiform. |
