terior ventral setæ on the last segment, long legs and long po- 
sterior tactile setæ, but even in the organs named differences are 
found, and in several other respects it is very distant from P. 
Hualeyi. The other species, P. armatus, is even more aberrant. 
But in spite of various difficulties both species are more properly 
inserted here than in any other place.

Material. Only a young contracted male with eight pairs 
of legs. 
Head (fig. 5a). 'The eyes are somewhat shorter than the di- 
stance between them. — All dorsal hairs are cylindrical and thin, 
those in the three anterior rows and the submedian pair of the 
fourth row are "short, partly even very short; the intermediate setæ 
in the fourth row are slightly more than half as long as the eyes 
and a little longer than the sublateral pair. 
"sAntennæ (fig. 5a).. The two front hairs on the fourth joint 
are proportionately short, the lower one about as long as the joint 
and a little longer than the upper one. The upper branch is three 
and a half times longer than broad, scarcely as long as the two 
distal joints of the peduncle;- its flagellum "is comparatively short, 
a little more: than two times longer than the branch and only å 
little more than half as long as the breadth of the head. The lower 
branch is slightly shorter than the upper, widening considerably 
from the base to the insertion of the anterior flagellum, two and a 
half times longer than broad, and the anterior angle is broadly and 
very obliquely cut: off. The posterior flagellum is a little longer 
than the anterior and slightly shorter than that; of the upper branch; 
all three flagella are rather slender, not thickened towards the end. 
The globulus is large, almost as broad ag the upper branch; its 
stalk is slighily shorter than the transverse diameter of the globulus. 
Trunk (fig. 5%).  Moderately robust. — Only four pairs of 
Falk: setæ are present, the specimen being immature. The last
