line with the posterior end of the anterior lateral shields, and 
near the edge. A third pair more inward and on a line with 
the proximal ends of the trochanteres III; a fourth pair ditto 
of trochanteres IV. Inside of the foremost pair of long hairs 
(on the omoplatal shields II) a pair of short fine hairs. Finally 
each horn ends in a hair a little shorter than the prosoma ; 
outside of the pedestal of this hair a very small pedestal with 
a hair as long as the width of the abdomen ; inside of the 
horn a much longer pedestal with a hair as long as the whole 
body, and inside of this pedestal you observe on the velum 
a short and very thin hair. 
Ventralside (Fig. 49). Epimera I joined nearly in 
their whole length, so that only their foremost free parts 
surround the throat as a collar. Epimera II as long as epimera 
I. Epimera II like in the nympha exactly marginal, exten- 
ding to the line of demarcation between prosoma and meta- 
soma. Epimera IV slightly bent S-like, long, even longer than 
_epimera I or II. Behind legs IV there is a »fifth epimeron«, 
short, as long as the trochanter IV.Shieldsabsent. Epian- 
drium small, horse-shoe-shaped, on a line with the proximal 
ends of trochanteres III. Penis small, rodlike. Anus term- 
inal, i.e. touching the so-called ineision. This is a proof 
of the fact that the velum is a secondary organ, and its cleft 
a tertiary one. Anal suckers oval, or better circular, but, 
standing against a slope, simulating ovals, with their centres 
on a line with the top of the so-called incision. H airs. 
Inside of the distal half of epimera I a pair of short thin 
hairs. Outside of the proximal half of epimera IV a pair of 
ditto. Outside of the so-called epimera V a pair of ditto. On 
the enlarged proximal end of epimera IV a pair of long hairs, | 
much longer than the width of the body. Outside of the ends 
of the abdominal lobes, on short pedestals a pair of thin hairs 
as long as the width of the abdomen. Lateral hair longer 
than the width of the body, in fact dorsal (fig. 48); its accom-
