Caput qiiam segmenta duo priora peraäi brevius. Processus tibialis pedum joerwi primi paris 

 basin processus carpalis attiugens vel superans; margo anterior processus carpalis serratus, 

 mai-gine posteriore metacarpi longior. Carpus pedum tertii ac quarti parium valde dilatatus, 

 margine posteriore convexo. Pedes triuiii parium ultiinorum pedibus tertii ac quarti parium 

 multo longiores; femur dilatatum; metacarpus valde elongatus, metacarpo pedum tertii ac 

 quarti parium multo longior. Latera segmentorum p/fi rotundata. Pedes uri primi paris

The head is shorter than the first two peraeonal segments. The tibial process of the first 

 pair of perceopoda reaches to the base of the carpal process or farther; the front margin 

 of the carpal process is serrated, longcr than the hind margin of the metacarpus. The 

 carpus of the third and fourth pairs is very dilated, the hind margin convex. The last 

 three pairs are much longer than the next preceding two pairs; the femur is dilated; the 

 metacarpus is very elongated, much Icmger than the metacarpus of the third and fourth 

 pairs. The lateral parts of the pleonaJ segments are rounded. Tlie first pair of uropoda 

 are far from reaching to the apex of the last pair; the outer ramus is shorter tlian the 

 inner. The inner ranuis of the last pair is longer than the breadth of the peduncle. The 

 telson equals a third of the length of the peduncle of the last pair of uropoda.
