genera have been proposed on very slight grounds, so that 

 it is sometimes difficult to be sure as to which of several genera 

 a new species should be referred. All the new species here 

 described, however, may be placed geuerically by the 

 appended table, which, as far as possible, is based on charac- 

 ters previously used by Baly. As rfegards the dentition of 

 the claws, with most of the species whose claws are truly 

 armed, if these can be seen at all clearly there is usually no 

 difficulty in noting the armature, but where the claws are 

 very feebly armed, or are unarmed, closer examination is 

 necessary, and in such it is usually necessary to examine 

 several claws, as with old, greasy or dirty specimens a small 

 amount of dirt may easily cause a claw to appear armed 

 when it is really simple.
