as long as thick distally, second and third each 0,17 mm. long, fourth 0,31 mm.; chela 

 0,68 mm. long, a little longer than the second to fourth segments taken together; palm 

 slightly longer than the fingers. Proportion between the length of the carpus and the width of 

 the fourth article 8. 



The legs of the third pair agree as regards their relative dimensions with those of the 

 other specimen, the small tooth at the end of the merus appears a little less acute. Propodus 

 with 10 spinules, dactylus as in the other specimen.

The ova of the female from Stat. 78 are numerous, small, 0,6 — 0,63 mm. long, those 

 of the other specimen are a little larger and less numerous. 



The female from Pulu Pasi Tanette may, as was already remarked, once prove to belong 

 to a species different from that collected on the Borneo-bank ; it differs especially by the joints 

 of the outer antennular flagellum being longer than thick and few in number, by the second 

 and the third segment of the carpus being equal, by the less strongly arcuate carapace, by a 

 smaller size and by larger ova.
