 has the lower back angle obliquely rounded off, and is furnished with a smooth 

 and peculiarly long claw, which when pressed in reaches with its point back 

 to the middle of the hand. It might therefore be veury well considered as 

 the type of a separate genus. It is also remarkable for the 3 rd caudal- 

 segment's lower and back angles, which are carried out into a very, long 

 sharp point bent upwards, and for the mandibulae which have the cutting 

 or eggbearing end very small and the tuberculum molare very large hard and 

 prominent. The 1 st pair of maxillae have no side-teeth on the large spines 

 at the end of the outer branch, and their palp has a great number of den- 

 ticles at the point. The second pair of maxillae have the branches very
