Species of Opisthophthalmus. 157 



male. Carapace slightly longer than the first and second caudal 

 segment (somewhat shorter than these segments in the 3 ) ; inter- 

 ocular area almost entirely smooth, or weakly granular in the anterior 

 part (in the $ finely granular over almost the whole surface or only 

 on the anterior half). Terga granular throughout (more densely and 

 finely so in the <?). Sterna smooth and shiny, the last with the 

 rudiments of lateral keels just visible and a few weak granules in the 

 region of these keels, the mesial portion of the segment either quite 

 smooth or more commonly, just perceptibly rugose-granular. (In 

 the $ the last segment is very densely and finely granular, with 

 rudiments of lateral keels.) Humerus of palpi with the anterior 

 border of upper surface as well defined as in the male ; hands broad 

 and stout, convex above, less hairy ; finger-keel strong, smooth ; inner 

 part of upper surface of hand covered with numerous, low, fiat, 

 anastomosing elevations, secondary keels obsolete, indicated by black 

 lines.
