the stylocerite reaches to the distal third part of mediau article 

 and the carpocerite is 3,35-times louger thau wide, in stead of

 middle of 3rd autenuular article. 



Posterior margin of the telsou wider with regard to the length 

 thau that of Syn. streptodactylus, the length being 2,375-times 

 the width of the posterior margin ; spinules of upper surface small, 

 the anterior pair before the middle, but the spinules nearer to the

 height 1,5. Anterior margin of the palm, uear the articulation of 

 the finger, with an acute, spiniform tooth. 



Relative dimensions of the small chela: fingers 1; total length 

 3,1; height 1,1. Meropodites of both chelipedes with a spiniform 

 tooth at the end of the upper margin. 



First carpal article of 2nd legs as long as the chela, but one 

 fifth shorter than the sum of the four followiug. Relative dimen- 

 sions of 3rd pair: meropodite 2,61; carpus 1; propodite 2,72. 

 Meropodite 4-times, propodite 7,3-times longer than wide, mero- 

 podite with four spinules on the distal half, propodite with nine. 

 Dactylus 74 of the propodite, of a less sleuder form than in Syn. 

 streptodactylus, the dactylus being 2,5-times longer than wide, 

 in stead of 3-times; ventral hook also stouter.
