Diagnosis. — Two blunt lateral teeth. Sides of carapace conver- 

 gent anteriorly. Propodus of legs two and three slightly widening 

 distally; anterior distal lobe of merus subrectangular. Posterior 

 margin of propodus and proximal half of dactylus of leg one clothed 

 with shaggy hair in adult male. 



Description of typical specimens. — Elevations of carapace covered 

 wdth small tubercles composed of a few granules and with single 



granules. Four frontal lobes well 

 defined; median sinus an equi- 

 lateral triangle, lateral sinuses 

 small but well marked, lateral 

 teeth much less advanced than
