78 DISCOVERY REPORTS 



Oviger long and slender. Terminal claw two-thirds of tenth segment, armed with 

 fourteen short spinules. Total number of denticulate spines 39 (13+10 + 8 + 8). 

 Segments 4-6 as represented in Fig. 37 J, in the proportions 2:2-3:1; segment 5 

 straight, of almost uniform diameter throughout, with a few hook-like spines near the 

 distal articulation (Fig. 37 d). 



Third leg long and slender, sparsely beset with short, spinose setae on the three main 

 segments. Second coxa a little longer than the sum of the first and third (dorsal 

 measurements). Femur slender and, like first tibia, expanded in the distal third 

 (Fig. 36 c), more than half as long again as the three coxae together; gland openings very 

 inconspicuous, about ten in number. Second tibia the longest segment, approximately 

 five times the sum of tarsus and propodus. The latter slightly longer than the former 

 and armed ventrally with six or seven spines (Fig. 37 c). Claw rather more than half 

 as long as propodus ; auxiliaries very long — at least two-thirds of claw.

The female is very similar to the male, but segments 4-5 of the oviger are relatively 

 short. The femur is rather more robust and of almost uniform diameter throughout ; 

 the first tibia is expanded distally as in the male. 



Remarks. The only species of the genus Ny77iphon previously reported from West 

 Africa is A^. graciUmum, Caiman (Loman, 1923 b, p. 5). N. angolense difl^ers from the 

 holotype of that species in several respects : (i) there are at least twice as many spinules 

 on the fingers of the chela, (2) there are a few hooked spines near the distal articulation 

 of the fifth segment of the male oviger, (3) the tarsus does not exceed, although it may 

 nearly equal the propodus, (4) the auxiliary claws are more highly developed, and 

 (5) the first tibia in both sexes, and the femur in the male, is expanded distally.
