' Åccording to Stuxberg and, after him, Saes, this species should be 

 ideutical with tlie tirst Cuniacean described, viz. Oniscus scorpioides Lepechin 

 1778. As I have had uo opportunity of Consulting the paper in which Le- 

 pechin described his OniscM-s, I can prononnce no opinion as to the correct- 

 ness of Stuxberg'8 identification, but I retain for this form the name given 

 by Kröyer.
