b 7 . Legs shorter; length of first femur and 



third tibia less than twice the width 



of the carapace ; second tibial of 



fourth leg less than distance between 



the eyes. 



a 8 . Femur of chela armed below with 6 



spines ; the first spine on the upper 



edge of femur longer, equal to 



about half the second spinimana, Pocock. 



b 9 . Femur of chela armed below with 



5 spines, first on upper edge of 



femur less than half the second . . Thoreliii, sp. n. 



h*. The first and third inferior spines on 



tarsus of chela nearly obsolete ; frontal 



process prominent tesseWata, Pocock. 



b 5 . Tibia of chela stouter, spines shorter, none 



of them so long as the thickness of the 



segment. 



a 9 . The first and third inferior tarsal spines 



of chela moderately long. 



a 10 . Femora of legs not distinctly spotted, 



pattern of abdomen obscure ; eyes 



more widely separated santarensis, sp. n. 



b 10 . Femora of legs distinctly spotted with 



yellow, a yellow ring round the tergal 



impressions ; eyes closer together . . pulchripes, sp. n. 



b". The first and third inferior tarsal spines 



of chela minute. 



a 11 . Distance between the lateral eyes 



equal to about half the median length 



of the carapace ; of larger size reniforme (Linn.) *. 



ft 11 . Distance between the lateral eyes 

 greater than half the median length 

 of the carapace. 

 a 1 -. Distance between the median ocular 

 tubercle and the anterior edge of 

 the carapace less than the long 

 diameter of the tubercle ; first supe- 

 rior tarsal spine distinct but small. 

 a 13 . Frontal process invisible from 



above ; darker, variegated .... Gervaisii, sp. n. 

 b 13 . Frontal process completely visible 

 from above ; abdomen pale, of a 



uniform colour barbadensis, Pocock. 



b 12 . Distance between the median tu- 

 bercle and the anterior edge equal 

 to twice the diameter of the tu- 

 bercle ; first upper tarsal spiue

* Syn. Pallasii, Blanchard ; see Note, p. 297. 



t The species I described as Keyserlingii in Journ. Linn. Soc, Zool. 

 xxiv. p. 589, is referable, I now think, to this species. On p. 540 of the 

 above paper I compared Keyserlingii to a species named scabra ; for 

 scabra, Pallasii, Blanch., should be substituted, the former being the 

 name I had applied to the species before discovering that Blanchard had 

 already given it a name. (See also Note, p. 297.)
