 PORCELLANA VALIDA. 



Violaceas et granulosae affinis. Carapax fere Icevis, utrinque obsolete 

 marginatus, fronte planus, quoad marginem orbitd paulo excavatus. 

 Antennae externce flagello parce pubescentes, pilis latitudine flagelli 

 longioribus. Articulus pedum k-torum Stius latus, 5tus paulo hir- 

 sutus, 4hts prope apicem parce hirsutus. Carpus manusque subtiliter 

 granulati ; manus superficie partim villosa. 



Near the violacea and granulosa. Carapax nearly smooth, with a mi- 

 nute margin either side, front plain, the front margin excavated by 

 the orbit. Outer antennas having the flagellum sparingly pubescent,
