the hinder border and the ocular tubercle; the radiating grooves 

 conspicuous ; tubercle small, transverse ; eyes small and compact, 

 those of the front line sliglitly procurved, subequal and equidistant, 

 the distance between the medians less than a diameter; the posterior 

 median eye less convex, but co\ering a larger ai'ea than the posterior 

 lateral. 



Lower surface of mandible armed internally with 10 strong 

 teeth, the posterior half of this surface covered with numerous 

 smaller granular teeth. 



Legs. JPatella and tibia of 4th and of 1st shghtly excelling the 

 length of the carapace ; the distal segments of the 3rd and -Ith 

 pairs covered with erect curled bristles somewhat as in Coremio- 

 cnemis, though less thickly ; the proiarsal scopulae not distally 

 incrassate as in Phoneyusa and Hysterocrates, the scopulae extending 

 practically to the base of the segments in the legs of the 1st and 

 :^nd pairs, but not covering half the segment in the 3rd, and 

 represented by merely a small patch on the 4th; the tarsal scopulae 

 complete and thick on the 1st, 2iid, and 3rd, but very weak on 

 the 4th, being intermixed with setae, and consisting of a narrow 

 band on each side of the middle line. 



Jleasurements in millimetres. Total length 36 ; lengcli of cara- 

 pace 17, width 15 ; length of 1st leg 47, of 2nd 43, of 3rd 39, of 

 4th 52 ; patella and tibia of 1st 18, of 3rd 13-5, of 4th IS. 



Loc. yierra Leone. A single female example {Siirffeon-Cajjt.

Some of the characters mentioned in the specific description 

 may prove ultimately to be of generic importance as compared 

 with Selenogijrus and other genera. Attention, for example, may 

 be drawn to the scopidfe and hair-armature of the 4th leg, the 

 size of the granular area on the lower surface of the mandible, 

 size of the eyes, &c. 



Genus Selexogthus, no v. 



Carapace oval, elongate ; fovea small, linear, but strongly pi'o- 

 curved as in Seltnocosmia ; cephalic area moderately elevated ; ocular 

 tubercle transverse, moderately large. Eyes \dth anterior row 

 nearly straight, slightly procurved ; posterior row recurved. 



Mandibles without external scopula, armed below with a single 

 row of teeth. Maxillce. without stridulating organ, the basal inner 

 angle, like the labium, thickly spinulose. Labium transversely 

 oblong, at least one-third wider than long. 



Legs moderately long, 4, 1, 2, 3 ; the 4th (measured from the 

 base of the femur) considerably longer than the 1st ; tarsal and 

 protarsal scopulas entire on 1st, 2nd, and 3rd legs ; tarsal scopula 

 of 4th divided by a narrow band of setfe ; that on the protarsus 

 also almost entirely divided ; protarsal scopulae of 1st and 2nd legs 

 broad only in the distal half of the segments, not extending quite 

 to the base on the 1st, covering a little less on the 2ud, only 

 occupying the distal half on the 3rd and the distal third on tho
