tibia and tarsus are shortly pubescent and very long, that on the 
tibia being three fourths as long as its joint. 
Copulatory Organs (fig. 1i). Seen from the front they are 
obliquely conical; the inner margin is straight; the outer somewhat 
convex and the apex blunt. 
Length. It is the largest species hitherto known. Adult fe- 
males from Denmark measure. 15 to 1-7 mm. in length. Speci- 
mens with the full number of legs from Italy varied from 1-4 to 
"7 mm. in length, and the smallest of these was an adult male. 
Variation... The Danish specimens are on the whole larger 
than several from various localities in Italy, but it must be added 
that Berlese mentions the length 1-75 mm. I have found small 
variations in several structural features, but all are gradually, and 
I think it impossible to discern a large Italian specimen from a 
Danish one. The most important difference is found in the anal 
plate, and my two figures; 1f and 1h, exhibit the highest degree 
of difference observed; in the small animal from Italy the plate 
is somewhat longer in proportion to its breadth than in the Danish 
specimen, the inner branches diverge distally and are tapering, 
while they are parallel and cylindrical in fig. 1f, the outer branches 
are a little longer and less diverging in the Italian specimen. But 
in a rather large specimen from Scilla the plate and its branches 
are shaped almost as in Danish specimens, only the outer branches 
being less diverging than in my figureulf, but agreeing with those 
in a smaller specimen from "Denmark. Furthermore small differences 
are found in the length of the setæ on the anal segment; on the 
head the sublateral setæ in the fourth row are sometimes clavate, 
and the submedian ones in the såme row vary somewhat in length. 
Locality.; Im Denmark I have captured the species two 
times, In July 1891 numerous specimens — all females and young 
ones — were taken in the Island of Bornholm; they lived in the 
forest ,, Almindingen" "under stones and lumps of dried clay in a 
cleft.. In July 1892 I found numerous specimens (likewise females 
and young ones) in the Island of Møen, partly in ,,Klinteskoven"
