" Carapax laevis, regione postica transversim convexa. Orbita 

 margine externa trifissa vel trilobata, lobis parvis, obtusis. Antennas 

 ut in Carpilio (ut in Liomera ? ). Grnathopoda intima lacinia ad apicem 

 non f urcata. flectognathopoda ischio longitudinaliter sulcato ; mero 

 superficie versus angulum internum excavata, margine anteriore con- 

 cava. Chelopoda manu facie externa sulcata. Pedes ambulatorii valde 

 setosi, mero compresso, snperne spinoso. 



" Liomeras affinis, sed carapace angustiore, pedibus setosis spino- 

 sisque." 



This genus is not represented in the Indian Museum.

" Carapace transverse, about once and a half as broad as long, 

 smooth, glabrous, and shining, with tbe interregional sutures almost 

 obsolete ; the two posterior teeth of the antero-lateral margins are the 

 only ones developed, and are very obscurely marked and obtuse. The 

 front is somewhat produced, and is divided by a median and two lateral 

 incisions into four lobes, of which the two median are broad and 

 truncated, and the lateral (or inner orbital lobes) are small and denti- 

 form. On the upper orbital margin are three small obtuse teeth 

 (including that of the outer orbital angle) ; the tooth at the inner 

 and lower orbital angle is rather prominent. The merus-joint of the 

 outer maxillipeds is rather small and transverse ; and this joint has a 

 shallow pit on its outer surface. The anterior legs (in the male) are 

 rubust, smooth ; arm or merus-joint with a series of spinutes on its 

 upper margin ; carpus smooth, with an antero-internal tooth ; peuulti-
