Length. Ihe adult and moderately extended male measures 
*72 mm. 
Variation. An adult specimen from Dønmark is *69 mm. long; 
of two adult spøcimøns from Germany one is a little shorter, while 
the other, whicli is somewkat contracted, only measurøs *55 mm. 
As to the characteristic anal plate (with its two branches from 
the postørior angles as long as the plate and considerably diverging, 
while two other branches are rudimentary and placed rather distant 
from each other) and in the structure of the third pair of tactile 
setæ these specimens agree rather well with the specimen described 
above, but especially in the German specimens the tactile setæ of 
the last pair are somewhat shorter, and in one of the specimens 
with the eyes distinet enough for observation these areas are con- 
spicuously longer and more approximate to each other than in the 
specimen figured on pi. V. Nevertheless, these specimens must be 
considered as belonging to the same species. 
Locality. One specimen was captured (by the author) in a 
wood of olive trees at Palmi, Calabria, May 17. 1893. A 
specimen has been secured (by the author) in the Danish Island 
of Møen, another at Hellebæk near E ls i nor e, Se aland (Dr. 
Th. Mortensen). Mr. C. Borner has taken some specimens at Mar¬ 
bur g (Hesse, Germany). 
Remarks. The species is very closely allied to P. vulgaris, 
but it is easily and sharply distinguished by the anal plate and 
the third pair of tactile setæ; furthermore it is smaller than al¬ 
most all specimens of P. vulgaris. I did not find any specimen 
piesenting a transition pr connecting link between P. vulgaris and 
P. gracilis in the two essential characters mentioned, and I must 
therefore consider them as two distinet species.

Material. Two adult specimens, male and female, have been 
examined; both were rather well preserved.
