from the Anglo-Egyplian Sudan. 221 and those on tlie posterior side only two in number. Claws of the second third, and fourth pairs of legs much longer than in Galeodes, those of the legs of the fourth pair being tlie longest (fig. 1 and fig. 2).

Othoes floiceri, sp. n.

Immovable finger of the chelicera with the second and fifth teeth (counting from the distal end) the largest ; the posterior of the two teeth which are present between these major teeth is exceedingly minute; first tooth of the row of large size and separated from the second by a fairly large gap. Between the two large teeth of the movable finger, also, two minor teeth are present, and the post'crior of them is very minute (fig. 3). Maxillipalp very long and slender, Othoesjloioeri, gen. et sp. n., chelicera from the inner side.

and its femur is furnished below, on the inner side, with a row of about five or six fairly strong spines and also with weaker spines ; patella and tibia without either thorns or bristles, the latter narrowed distally ; tarsus freely movable and more slender and not so abruptly narrowed as is the case in tiie species of Galeodes—moreover, it is furnished with a scopula composed of forked hairs, similar to those at the end of the tarsus of the first leg. Handles of the maleoli about equal in length to or a little less than the greatest length of the blades. Metatarsus of fourth leg with the spinal armature (1 + 1) +1 + 2 + 2, but the proximal unpaired spines (enclosed in brackets in the formula) are much weaker than the others. The spinal armature of the tarsus of the fourth leg is I 2 + 2 + 2 i 2 I I . Colour.—Body, chelicera3, and legs pale yellow ; a fine blackish line is present, however, along the anterior margin of the head-plate, and the ocular tubercle is also black, but it has an ill-defined longitudinal yellowish streak in the middle. Patella and tibia of maxillipalp black and the tarsus sliglitly darkened ; the basal segments of this appendage are pale yellow.
