WEsTtwooDp has much later, in his Thesaurus Entom. Oxon., 
p- 201, P1. XXXVI, fig. 5 (1874) described and figured a spe- 
cies from the Amazones, which is nearly related to Crypto- 
stemma Westermanni, and to which be has given the name 
Cryptocellus foedus, thus creating a new genus for it, and uni- 
ting the two genera in the family Cryptostemmoide [-mide]. 
WeEstwWoop's description is very full and detailed; but when 
he says that the palpi are fixed on the coxe of the 1:st pair 
of legs, he commits, I think, an error. The palpi are in 
Cryptostemma, GUER.. nob., a sin other Opiliones, and doubtless 
also in Cryptocellus, fixed on the maxille: the coxe of the 
1:st pair are, however, in these animals easily overlooked. 
being almost concealed by the palpi: thev are wedge-shaped, 
with the pointed, inwardly directed base »ot reaching the 
middle line of the »sternal surface» formed by the cox&e and 
the maxille, with which latter they are intimately grown 
together, and which thus may easily be taken for the coxe 
in question. 
In a paper with the title: Sopra alcuni Opilioni (Pha- 
langidea) d'Europa e dell'Asia Occidentale, etc.,' I have, on 
the strength of the characteristics alleged by WESTWOOD, ex- 
pressed the opinion that his Cryptostemmoidae diverged so 
much from other Öpiliones, that it was necessary to create 
for them a separate Suborder, which I called Kieinulei. The 
differences pointed out by me were principally these: The 
abdomen consists only of four segments, besides a small anal 
one; the cephalathorax forms in front a moveable, downwardly 
directed hood (>labrum>), which covers and conceals the man- 
dibles; the cox& are united with each other along the middle 
line of the under side of the cephalathorax, and the palpi 
consist of only four joints. But to these characters the follow- 
ing must be added: the maxille are grown together with 
each other and with the cox&e of the 1:st (and 2:nd) pairs of 
legs; they are immoveable, like the coxe, which are all devoid 
of a maxillary lobe. The mandibles are directed downwards 
and are formed of two joints only, of which the second has 
the form of a long and rather slender claw directed inwards, 
so that the mandibles in these animals resemble very nearly 
those of the true Spiders, though they may be called didac-
