 28 ; patella + tibia of 1st leg 12, tibiae of Si-d 6. 

 Loc. Cameroons. 



Sparassus rufilatus, sp. n. (Plate LVI. figs. 13, 13 a.) 



S • Colour much as in S. trifiircatus, except that the legs are more 

 orange-red, though the bases of the femora remain pale ; the upper- 

 side of the abdomen studded with dark reddish-bi'own spots and 

 the lower side behind the epigastric fold uniformly pinkish brown. 



Carapace very slightly longer than wide, less than tibia of 3rd 

 and than half the patella + tibia of 1st leg. 



Eyes of posterior line slightly procurved, subequal and subequally 

 spaced ; eyes of anterior line closer together, equally spaced, 

 distance between medians about half their radius. 



Legs very long, 2nd surpassing 1st by its tarsus and one 

 third of its protarsus ; 2nd leg about seven times as long as 

 carapace. Tibia without apical inferior spines ; patellae unspined. 



Palp with tibia cylindrical, much longer than patella, and armed 

 internally with a single long spine ; patella unspined ; tibial 

 apophysis consisting of aforwardly directed spur, the apex of which 

 is pointed and hooked ; tarsus very large, its external edge concave, 

 internal convex ; palpal organ constructed as in fig. 13, Plate LVI. 



Measurements in millimetres. — Total length 14; length of carapace 

 6-5, width 6 ; length of 1st leg 40, of 2nd 45-5, of 3rd 29, of 4th 

 33 ; patella + tibia of 1st 14-8, tibia of 3rd 7-8. 



Loc. Cameroons. 



The females of the foregoing species may be recognized as 

 follows : — 



a. Head narrower, its width ouly equal to the length between 



the anterior end of the foA ea and the posterior line of 

 eyes ; eyes closer together, the ocular quadrangle scarcely 

 narrowed in front ; mandibles reddish brown ; tibia with 

 3 pairs of inferior spines ; patella at least on 2nd and 3rd 

 legs spined in front and behind ..' benitcnsis, sp. n. 



b. Head broader, its width almost equal to the entire length 



measured from the apex of the fovea ; eyes more widely 

 spaced, the ocular quadrangle distinctly narrower 

 in front ; mandibles black ; tibiae with two pairs of 

 spines beneath ; patellse unspined hated, sp. n . 



The males of the species here described may be determined 

 as follows : — 



a. Tibial process of palp trifurcate (tibiae of legs without 

 inferior apical spines ; 2nd leg a good deal longer than 

 1st, and only a little more than five times as long as 

 carapace; patella and tibia of palp without spines) ... irifurcatus,s^.n. 

 h. Tibial process of palp simple, undivided. 



a^. Tibial process stout at base, its distal half slender and 

 bent downwards almost at right angles ; tibiae of legs 

 with two pairs of inferior spines ; 2nd leg only a 

 little longer than 1st, and less than six times as long 

 as carapace; tibia of palp strongly spined benitcnsis, sp. n
