DUTCH BORNEO-EXPEDITION. 125 



but flattened at the base and covered with small, acute, little 

 pi'ominent granules, that are more crowded on the lower 

 margin than on the outer surface. The dactylus is also 

 covered with similar granules, especially above, and under 

 a lens rows of very fine puncta are moreover observed, 

 but the fingers are not grooved. Both fingers carry 

 some small teeth, two of which on the index are somewhat 

 larger than the others. The inner surface of the hand is 

 almost smooth. 



The smaller chela measures only two thirds the width of 

 the cephalothorax, the palm is a little less high than long, 

 and the fingers that are slightly longer than the palm, 

 are distinctly grooved longitudinally, each groove presenting 

 a row of puncta. The fingers are more slender than those 

 of the other hand and more feebly toothed. 



The ambulatory legs are long and slender, so are e. g. 

 those of the penultimate pair three times as long as the 

 cephalothorax. The meropodites of this pair, just as long 

 as the latter, are three times as long as broad ; the 

 propodites of this pair, half as long as the cephalo- 

 thorax, are 2'/2-times as long as broad in the middle and 

 the dactylopodites are a little longer than the pro- 

 podites. 



The dactylopodites are slender, straight and quite 

 narrow, tapering but very slightly towards the extre- 

 mities, so are e. g. those of the penultimate pair about 9- 

 times as long as broad at the base; they are armed with 

 several small spinules along their edges. The posterior 

 margin of the propodites, that are covered with small 

 depressed granules arranged partly in a longitudinal row, 

 carries also 6 or 7 spinules, the anterior margin of the 

 meropodites is quite unarmed, without a tooth at the distal 

 end and their outer surface is covered with a few small 

 rugosities, except those of the last pair that are smooth. 

 For the rest the ambulatory legs are glabrous.
