dorsal row of the patella consists of clumsy pointed hairs, the inner 
marginal row of clumsy pointed hairs and the outer one of fan hairs. 
Along the sides there are rows of clumsy pointed hair. The tibia 
bears an inner dorsal marginal row of pointed hairs and an outer 
row of fan hairs and pointed hairs. Along the sides there are 
pointed and fan hairs, below at the inner side both fan hairs and 
pointed ones, but at the outer side only pointed ones. The arrange- 
ment .of hairs in the metatarsus is like that of the tibia with the 
exception of the inner marginal row of pointed and fan hairs and the 
outer marginal row of fan hairs as well as of the usual median dorsal 
row. The tarsus bears two inner proximal fan hairs and a single 
outer one, but the cloven hair is missing. The claw joint is like 
that of the second pair of legs. 
Inner anatomy. Ås far as I have been able to see through 
the skin, the inner anatomy does not seem to be quite similar to 
that of Eu. segmentatus. The intestine is — at least behind — 
twisted to the left towards the vent; it is filled with the same 
round bodies. Especially the structure of the accessory glands of 
the male differs very much, as seen in pl. VI fig. 19. In front 
of the indistinct genital opening the two usual ,,copulatory suckers" 
(s) are seen and a transverse ,,vestibulum" (v). This is continued 
into a large sac (g) the median unpaired gland which is very 
much enlarged behind and laterally. Seen from below the sides of 
this median sac are covered in front by a large sac on each side (%), 
the paired median gland and are placed themselves above a pair of 
rather short sacs (7), paired lateral glands; the posterior paired 
median glands seem to be missing, if not corresponding to the 
lateral hindmost part of the median sac (i); it will thus be seen 
that there are so great differences between the systems of the two 
species, that even the comparison seems doubtful. 
Colour. The colour is most like that of Eu. segmentatus. 
The median triangular spot of the head is well developed and 
reaches to the front margin of the head; on account of that the 
front marginal spot has been divided into a right and a left irregular
