shaped almost as in P. Huxleyi ; its setæ as in that species, only 
the tu o outei paiis a little longer. — The styli are somewhat 
sorter and thinner than in P. Huxleyi, about half as long as 
the outei bianches of the anal plate. — The sternum and its setæ 
present no differences from the preceding species. — The anal 
plate (fig. 3 c) is considerably larger than in P.robustus ; the urner 
branches with their proximal portion narrow in the whole length, 
cylindrical, cut off transversely, and 011 the end is inserted the di¬ 
stal portion which is cylindrical, exceedingly siender, not half as 
broad but about half as long as the proximal portion; the outer 
branches are very diverging and reach to the middle of the distal 
portion of the inner branches. 
Legs. They are a little shorter and more robust than in p. 
robustus ; the last pair (fig. 3 d) is even rather shorter and thicker 
than in P. Huxleyi, and the tarsus is less elongated, but as to the 
relative length of the joints and the length of the setæ it does 
not present any essential difference from the last-named species. 
Length. The single adult female specimen measures *92 mm. 
Locality. The specimen was captured at Temuco in Chile 
(see page 360). 
Remarks. Especially by the slight difference in length be- 
tween the flagella of the lower antennal branch this species is 
sharply distinguished from P. robustus ; the dimension of the glo- 
bulus and the anal plate present other distinctive features. As to 
the differences between this species and the following one I refer 
to the „ remarks “ on page 365.

PI. II, fig. 4 a—4 h. 
Material. An adult male is examined, it has been flattened 
to a certain degree by the pressure of the glass-cover. 
Head (fig. 4 a). It is shown in the drawing as it has been 
found: obliquely flattened and deformed. The only difference worth 
mentioning between it and the head of P. robustus seems to be
