The Notostigmata, a new suborder of Åcari. 
By 
th. 
(Copenhagen.) 
With Plates IV—VI, 
Introduction. 
The following studies on this new suborder have been made 
on material included in the famous French Arachnologist E. Simon's 
rich collection and lent by him to Drs. H. J. Hansen and W. Søren- 
sen. Through the kindness of the two Danish Zoologists and the 
great liberality of M. E. Simon I got the animals (two species) to 
study; the third species, Eucarus Italicus, has been received from 
the German naturalist Dr. €. Bårner. Here I take the opportunity 
of tendering my best thanks to these four gentlemen, chiefly. to 
M. E. Simon. I thank Dr. H. J. Hansen especially, because he 
has followed my studies with interest and "good assistance, letting 
me draw from his full zoological experience; these thanks are still 
more natural when taken into consideration that he has troubled 
himself by verifying and correeting a good deal of my observations 
and has given good drawings of the more difficult objects. 
I communicated some preliminary studies about the Notostig- 
mata at the ,,Congrås des Naturalistes et Médecins du Nord tenu å 
Helsingfors 1902', and a short résumé has appeared in the ,,Comptes 
rendus" of this meeting. This résumé as most preliminary notes 
ought to be classed together with superfluous litterature, all its 
facts being included in this paper.
