a^. Ocular tubercle strikingly high ; spines on 

 the chela very long, the first on the upper- 

 side of the tarsus much larger than the 



distal one macrops, sp. n. 



b^. Ocular tubercle lower, spines on chela 

 shorter, the first on the upperside of the 



tarsus smaller than the di.stal Icevifrons, sp. n. 



b^. The spines on the chelas shorter, the longest 

 on the tibia shorter than the width of the 

 segment : ocular tubercle low, not notice- 

 ably higher than the lateral eye-clusters ; 

 frontal process more concealed, fifth spine 

 from proximal end of upper edge of tibia 

 only a little shorter than the fourth. 

 a^. The distal spine on the upper edge of 



the tarsus longer than the proximal .... viricliceps, Pocock. 

 b^. The distal spine on the upper edge of the 



tarsus shorter than the proximal azteca, sp, n. 



J), Tibia of chela armed above with 7 or 8 spines, 

 of which the third from the proximal end and 

 the fourth or third from the distal end are the 

 longest, there being onlj' one spine between 

 these two. The number of spines sinks to 7 

 when what is the anterior spine or spinule in 

 some species disappears in others. 

 «*. The second spine on the tibia of the chela very 

 short, about g of the length of the third and 

 \ of the fourth ; there are thus only 3 long- 

 spines on this segment, and, owing to the 

 disappearance of the distal spinule, only 7 



spines altogether Whitei (Gerv.) *. 



i*. The second spine on the upper edge of the 

 tibia of the chela long, nearly as long as the 

 third and almost always longer than the 

 fourth ; there are thus at least 4 long spines 

 in this series. 

 a'. Tibia of chela slender, spines longer, the 

 longest spine exceeding the width of the 

 segment ; lateral eye-clusters mostly closer 

 together, the distance between them only 

 a trifle more than half the median length 

 of the carapace, the anterior margin of 

 which is more coarsely dentate laterally • 



than in the middle ; the median eyes not 

 far from the anterior margin ; mandible 

 with enlarged tubercle. 

 a^. The 6 spines on the tarsus of the chela 

 well developed ; frontal process almost 

 concealed. 

 a'. Legs exceedingly long; length of femur 

 of fu'st and tibia of third greater than 

 twice the width of the carapace ; 

 second tibial of fourth leg equal to 

 distance between eyes longi2Jes, Pocock. 



* The type of this species is ticketed Riirdwan (India), but probablv 

 erroneuusly.
