seen; on the margin itself a few forwardly directed spines are 

 visible. On the innerside of the hand there is along the outer 

 margin a deep furrow, and here also a row of small spines occurs. 

 The greater part of the innerside has however been inaccessible 

 for examination. Along the inner margin of the immoveable 

 finger, which is slightly concave , is found a row of oblong, 

 jagged teeth or nodes whereof two are much larger than the rest. 



The moveable finger is long (25 mm.) and narrow (at the 

 utmost 6 mm. broad). The upperside is flat, the underside I 

 have not seen. The outer margin is slightly convex, and has 

 a row of small, forwardly directed spines; the inner margin is 

 almost straight, and has, like the immoveable finger, oblong 

 teeth or nodes, whereof one at any rate far exceeds the others 

 in size. At the base of the moveable finger is a small point 

 or node, and opposite to this, on the hand, another but larger 

 node is seen. Whether or not these nodes formed a kind of 

 joint cannot now be determined. 



The surface of the chela seems to have been of the same 

 nature as the surface of the carapace. 



Of the rest of the walking feet I have only seen indistinct 

 remains; they seem to have been long and rather thin. 



The specimen here described has only the four first seg- 

 ments of the abdomen preserved. The first segment is only 

 8 mm. long, while the others measure 10 — 12 mm. On the 

 sides it runs into two rounded plates; about 1,-5 mm. from its 

 posterior margin is a furrow which , on the sides , retreats 

 more and more from the posterior margin, and at last ends 

 on the epimeral plates. On the following segments the epimeral 

 plates end in backwardly directed falcate points. Also these 

 segments have a transverse-furrow, but here it is found nearest 

 the anterior margin, on the sides it approaches still more the 

 anterior margin, but reaching the epimeral plates it forms a 

 backward curve, and at the same time it gets very deep; 

 however it soon disappears after having united itself with an
