the anterior part of the protogastric areas are distinctly rugose and 

 granular ; the front is higher, — 3 mm. broad, i mm. high ; the chelse 

 are granular on their outer surface and the five or six acute teeth 

 on the proximal half of the upper margin of the dactylus are nnicn 

 larger than in S. thelxinoe. The abdomen has a different shape, 

 resembling that of S. moeschii (de Man in Max Weber's Zoolog. 

 Ergebn., 1892, tab. xx, fig. 14a) ; the penultimate segment, in- 

 deed, is much less enlarged, its posterior margin is rg2 mm. broad, 

 while this segment is 0*9 mm. and the antepenultimate 0*72 mm. 

 long. Both species are therefore considered as different, but an 

 examination of younger individuals of S. thelxinoe will be useful 

 in order to see whether they show the same characters as the adult. 

 Sesarma (Sesarma) amphinome, de M., of which a female from 

 Sintang, described in 1899, is lying before me, is a more different 

 species.
