results of my study that it must now be taken as granted that we 
are only acquainted with a very small portion af a moderately rich 
order. Of the family Pauropodidæ only two European species had 
been described, viz. those discovered and made known by Lubbock 
thirty five years ago, while I have captured seven species on a 
small number of excursions and five of them in Denmark. I sup- 
pose that at least between twenty and thirty species of. this family 
live in Europe, and that the order contains in all several hun- 
dreds of species. 
At least the family Pauropodidæ has in all probability an al- 
most world-wide distribution, and will be found in all countries 
with exception of the arctic and subartice regions. C. 0. v. Porat 
writes (Entom. Tidskrift, Stockholm, Årg. 10, 1889, p. 67) that 
he has taken Pauropus Huæleyi near Jonkoping (in Sweden), a town 
situated about at 58? lat. N.; he also mentions that T. Tullberg 
had diseovered the same species almost at the same time as Lub- 
bock, and I believe that he captured it near Upsala, about at 60” 
lat. N. In Denmark, Germany, Austria and Italy the animals are 
not rare; in North America some species have been discovered. In 
this paper species from Chile, Paraguay, Argentina in South America 
and from Siam in tropical Asia have been described ; especially the 
discovery in Siam of proportionally numerous species shows that the 
family is even richly developed in a tropical country, and the col- 
lector, Dr. Th. Mortensen, complained of that he arrived to Koh 
Chang months after the cessation of the rainy season, therefore to0 
late for colleeting a rich material of such animals which live on damp 
places. — The Eurypauropodidæ and especially the Brachypauro- 
podidæ seem to be more rare, and on their distribution little can 
be said at present. — Finally I wish to emphasize that none of 
the European species have been found in America, and below it 
will be proved that specimens captured in North and South Ame- 
rica and stated in the literature to belong to the European Pau- 
ropus Huxleyi, are in reality other species.
