*) Haller's name of simplex was preoccupied in the genus Oribata by Gervais' 

 species (in: Gay, Hist, Chile), which Haller apparently overlooked; I have therefore 

 renamed the species in honor of Haller. A. D. Michael. 



**) Nicolets name 0. ovalis being preoccupied in this genus; and Berlese's name 

 0. Nicoletii which was intended to cure the difficulty; being, in my opinion, applied 

 to a different species, I have renamed this species. A.D.Michael.
