2. Segment 5 of (^ oviger distinctly curved (type I a). 



a. More than 10 spinules on each finger of chela (20-30 in adults). 



i. 26-34 denticulate spines on oviger; second coxa at least half as long again as 

 the sum of the first and third ; 8-9 femoral gland-openings, but no raised 

 tubercles ; tarsus at least half as long as propodus N. subtile, Loman 



ii. 19-22 denticulate spines on oviger; second coxa scarcely longer than the 

 sum of the first and third; 4 wide femoral gland-tubercles; tarsus only 

 one-third of propodus N. pfejferi, Loraan 



b. Less than 10 (6-9) spinules on each finger of chela [2-4 low, wide femoral 

 gland-tubercles]. 



i. Number of denticulate spines on oviger 17-20; tarsus half of propodus; 

 ventral margin of the latter setose N.paiicidens, n.sp. 



ii. Number of spines on oviger 5-9, not denticulate; tarsus one-fourth of pro- 

 podus; ventral margin of the latter spinose N. adareanuw, Hodgson 



II. Segment 5 of ,^ oviger relatively short — less than twice as long as segment 6 — and stout, 

 narrowed and slightly curved in proximal third (Fig. 10 h) [palpal segments 2-5 sub- 

 equal, long; auxiliary claws absent; second tibia the longest segment; 20 femoral gland- 

 openings; 40-50 denticulate spines on oviger; 75-110 spinules on movable finger of chela 

 (10-20 less on immovable one); tarsus, propodus and claws subequal] ...A^. charcoti, Bouvier 



III. Segment 5 of (J oviger long and slender; expanded somewhat at distal end (type I b) 

 [total number of denticulate spines on oviger 30-44]. 



A. Neck relatively long with oviger base inserted midway between first lateral process 

 and anterior cephalic lobe ; auxiliary claws absent [chela long and sickle shaped ; two 

 terminal palpal segments together |-| of second segment]. 



1. Second coxa more than twice the sum of the first and third; second tibia the 

 longest segment; 90-110 spinules on movable finger of chela; eyes present 



A'^. longicoxa, Hoek 



2. Second coxa less than twice the sum of the first and third (1-4 : i) ; first tibia the 

 longest segment ; 60-65 spinules on movable finger of chela ; eyes absent [spur on 

 distal end of femur; 12-13 femoral gland-tubercles] N. hamatum, Uoek 



B. Neck relatively short, oviger base in contact with first lateral process; auxiliary claws 

 present [second tibia the longest segment; second coxa long]. 



1 . Palpal segments 3 and 4 subequal and longer than 2 and 5 which are again sub- 

 equal ; fingers of chela curved inwards towards scape distally, each armed with 

 40-60 spinules ; 30 femoral gland-openings N. brachyrhynchum, Hoek 



2. Palpal segments 4 and 5 together rather longer than second segment, 2 and 3 sub- 

 equal ; fingers of chela not curved distally, each armed with 30-45 spinules; 10-12 

 femoral gland-openings N. clarencei, n.sp. 



IV. Segment 5 of ,^ oviger relatively short, portions of segments 5 and 6 or 3, 4 and 6 thin- 

 walled, inflated, often partially collapsed in fixed material (type II a); neck short, body 

 rather compact; auxiliary claws absent or vestigial. 



A. Second tibia the longest segment; 60-65 spinules on each finger of chela; 48-50 

 denticulate spines on oviger; tarsus shorter than propodus (4:5) [portions of 

 segments 3, 4 and 6 of cJ oviger thin-walled, segment 6 setose on the thin-walled area, 

 segment 5 short, slightly curved and widening gradually towards the distal end]
