part tapering; it is densely and very shortly plumose almost to the 
base. — The four posterior setæ on the penultimate segment are 
moderately long and" slightly tapering. The six setæ on the last 
segment are either all tapering and about one third as long as the 
posterior breadth of the segment, or the two submedian: pairs are 
cylindrical and only one fifth as long as the breadth mentioned, 
while the lateral pair is more normal. 
Anal -Segment (fig. 3b, 3c, 3d and 3f). The tergum is pro- 
duced backwards into a low protuberance, the hind margin of which 
is generally shaped as a small portion of a circle and rarely some- 
what angular (fig. 3f); the setæ are tapering, the two outer pairs 
always "subequal, much shorter than the longest setæ on the last 
segment of the trunk and at least a little longer than, often almost 
twice as long as, the submedian pair; the distance between the 
submedian setæ is considerably longer than between a submedian 
and an intermediate seta, while the distance between the lateral 
and the intermediate setæ is rather short. — The  styli are con- 
siderably thicker than the outer branches of the anal plate, cylin- 
drical and about half as long as the submedian setæ. — The ster- 
num with the posterior setæ tapering and a little more than half 
as long ås the breadth of the segment; the lateral setæ are tape- 
ring and about as long as the lateral dorsal pair; the anterior pair 
is more than half as long as the posterior pair, robust and clavate. 
— The anal plate is cleft in the median line ålmost to the base, 
and near the basal lateral angle projects the outer thin, cylindrical 
branch which is directed backwards and outwards, while the inner 
branches are shaped as exceedingly elongate triangles, which are 
two and a half times to four times longer than broad at the base; 
these inner branehes have their outer margins slightly concave, they 
are much longer than the outer ones and without any transverse 
division; all four branches are situated in the same plane. 
Legs:' They are not quite as long as in Stylopauropus ; they 
increase considerably in length posteriorly. The last pair (fig. 3 e) 
is long and slender; the femur is slightly longer than the trochanter,
