ACARINA FROM ALGERIA. 



417 



monodactyle ; a specie;? very similar to it, and erroneousl)' supposed 

 by some to be identical with it, has been found in Italy by Prof. 

 Canestriai, and called by him N. anauniensis. This creature has 

 the strong central claw and an exti'emely weak and small lateral 

 cluw on one side only, so that it becomes didactyle with very unequal 

 claws. In Algeria I find a creature which I have, with some doubt, 

 considered to be a variety of JV. anauniensis, and which does not 

 differ from Prof. Canestrini's species in any respect that I can see, 

 except that it has the weak lateral claw on each side of the central, 

 thus becoming tridactyle and completing the series.
