witb the Italian specimen, while for instance the inner branches of 
the anal plate present a sliape intermediate between those found 
J n the specimeus from the two countries. 
Locality. I have captured six specimens (together with nurne- 
rous specimens of P. vulgaris ) in „Dyrehaven 11 , a wood near C o- 
penhagen, under rottening leaves in a damp place in June and 
July 1891; but later on I never met with the species again. 
Furthermore I have examined two specimens taken at Marburg 
(H esse) b} r Mr. C. Borner, three not adult specimens secured by 
Dr. F. Meinert at Tu bi ngen and one specimen found by Dr. F. 
Sil vestri at Bevagna (Italy). 
Distribution. The figures drawn by Lubbock prove that our 
species is identical w T ith P. Huxleyi established on specimens captured 
at London. Furthermore I think that the form from Austria de- 
scribed by Latzel as the typical one is this species, but his variety 
filiformis is a mixture of at least two other species which are very 
distant from P. Huxleyi. The description and figures given by 
Berlese are imperfect (his figure of the anal plate is as bad as 
possible and exceedingly misleading), but as no other large species 
of this genus has been discovered in Italy I suppose that he has 
examined this species. It is impossible to decide if the specimens 
captured by P. Schmidt at St. Petersburgh and Narwa belonged to 
P . Huxleyi. C. v. Porat communicates that he has captured this 
species at Sanna near Jonkoping (Sweden) and that Tullberg had 
taken it about 1866 (I believe near Upsala). The species is thus 
widely distributed in Europe, but all statements on its occurrence 
in America are incorrect (see below). 
Remarks. P. Huxleyi is rather remote from all other species 
of the genus hitherto found in Europe. But it is closely alljed to 
tour American species, three of which are described below, while the 
fourth is that described by Kenyon (op. cit.) as P. Huxleyi. Jud- 
ging from fig. 42 in Kenyon’s paper this North American species 
has the inner branches of the anal plate divided by a transverse 
suture or articulation, but their shape indicates that the species can
