1. HERMACHASTES LIGHTFOOTI n. sp. 
Types: 8 3 (Nos. 657, 8543, 8550) and 2 ¢, all from the Cape 
Town side of Signal Hill, found under stones. 
g. Colowr.—Carapace pale ochraceous, the cephalic portion often 
faintly infuscated, more darkly so along the median line and towards 
the lateral borders; chelicerze, pedipalps, and legs pale ochraceous ; 
sternum and under side of the coxee of legs pale yellowish ; under

in the posterior part) pale yellowish, with a large spot above and a

* In all the species of this genus the inferior claw of the legs is large and very 
distinct, and the ocular area is at least twice as wide as long. In the? and young 
the claws of the legs are biseriately dentate below, one of the rows being more distal 
than the other although both generally overlap for a portion of their length; in the 
ad. ¢ the two are united to a single, long, spirally curving, numerously toothed row.
