v. 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^. 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'^. Femur of chela armed below with

/>*. The first and third inferior spines on 



tarsus of chela nearly obsolete ; fi-ontal

pattern of abdomen obscure ; eyes 



more widely separated santarensis, sp. n.

impressions : eyes closer together . . pidchripes, sp. n. 



b^. The first and third inferior tarsal spines 



of chela minute. 



a". Distance between the lateral eyes 



equal to about half the median length 



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



b^^. Distance between the lateral eyes 

 gi-eater than half the median length 

 of the carapace, 

 rt^-. Distance between the median ocular 

 tubercle and the anterior edge of 

 the carapace less than the long 

 diameter of the tubercle ; first supe-

 a". Frontal process invisible from

 b^^. Frontal process completely visible 

 from above ; abdomen pale, of a

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



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

 xxiv. p. 539, 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 svibstituted, the former being the 

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

 ali-eady given it a name. (See also Note, p. 297.)
