are the only ones provided with tactile hairs, seems to indicate 
that in this animal as well as in Amdlypygi (Phrynoide) and 
Uropygi (Oxopoei — Thelyphonoide — and Tartarides), these 
limbs serve the anımal as feelers, while walking. 
Lyriform organs we have not been able to detect, and as 
one of us is tolerably familiar with the appearance and occur- 
rence of these organs in other Arachnida'*, we think we may 
be allowed to say that they are wanting in Koenenza. 
The Abdomen is »stalked». Is consists of eleven segments, 
the first of which, forming the stalk, has been overlooked as a seg- 
ment by Grasst, who consequently only counts ten abdominal 
segments. Grassi has probably confounded it with the connecting 
membrane between the thorax and the abdomen. This mistake is 
natural enough, the first segment being very sligthly chitinized and 
therefore lacking the range of setæ which adorn the other ab- 
dominal segments. We therefore think we ought to point out 
that this segment is separated from the hindmost thoracic seg- 
ment and from the second abdominal segment by a groove which, 
though narrow, is very distinct and almost similar to the fur- 
rows which separate the other segments of the abdomen. These 
are adorned with a series, or rather a belt, of setiform hairs 
which are pretty equally distributed all round the segment. As 
usual in those Arachnida whose anterior abdominal segments 
can be distinguished from each other, the second is the genital 
one, viz. the one in which the genital organs have their ori- 
fices!?. As shown in fig. 2, the posterior margin is curved 
greatly backward (as in Zhelyphonord@) and besides the median 
part protrudes considerably (fig. 3), forming a kind of process 
which is emarginate in the middle so as to form two short down- 
14 We refer to the above-mentioned paper by one of us (H. J. HANSEN) 
about these and other organs in other Arachnida. 
15 We know quite well that this statement disagrees with the general 
belief, A few years ago R. I, Pocock even asserted that the genital segment 
was the first one in all Arachnida. — However, embryological researches by 
BRAUER in reference to Scorpions, and by PURCELL with regard to Aranec, 
have led to the result that the genital segment is the second, For further 
details we refer the reader to the above-announced paper in »Oversigt over
