is observed between the former and the articulation , some- 

 what closer to the latter than to the tooth on the middle 

 of the finger. The immobile finger presents two similar 

 teeth ; the distal one has the same size and form as the 

 middle tooth of the dactylus and is situated immediately 

 behind it, the proximal just behind the proximal tooth 

 of the other finger. A sharp cutting-edge unites on each 

 finger the distal tooth with the pointed curved tip. The 

 upper surface of the palm is closely covered with small 

 thorny spinules that occur also on the outer surface; on 

 the lower surface these spinules are somewhat larger and 

 stand not so close together and on the inner margin 

 they form two longitudinal, parallel rows of 

 larger spines, between which the surface is smooth. 

 The fingers are somewhat hairy. The carpus is covered 

 with similar spinules, rather closely set, except on the inner 

 surface, where larger spines form two longitudinal rows 

 and these spines have the same size as those on the inner 

 surface of the palm. Similar spinules are everywhere placed 

 on the merus, and they are larger on the lower surface 

 than on the upper. 



The left leg is 6 mm. shorter than the right and exceeds 

 the end of the antennal scales by the hand and two thirds 

 of the carpus. The latter is likewise a little shorter than 

 the merus and both joints have the same shape as in the 

 other leg. The chela is 2^1^ times as long as the carpus 

 and the fingers have the same length as the palm ; the 

 form of the palm is the same as in the other leg but it 

 appears scarcely broader than the distal end of 

 the carpus. The proportion of the width and thickness 

 of the palm is the same as in the other leg. The fingers 

 present also the same toothing, but the index is armed 

 with a third tooth just behind and contiguous to the 

 proximal one; they are likewise slightly hairy. As regards 

 the spinulation of the surface of the joints, both legs agree 

 with one another.
