into terrestrial and aquatic. Although M. Walckenaer has 
made of the last his final family of araneides, that of nayades, 
they have so much relation with the other tubiteles that, not- 
withstanding this disparity of habits, they must be placed 
with them. In those which are terrestrial, the tongue is 
almost square, or but little narrowed, very obtuse, or truncated 
at the summit. The jaws are straight, or almost straight, and 
move or less dilated towards their extremity. The two eyes 
of each lateral extremity of the ocular group, are in general 
tolerably distant from each other, or at least are not grouped 
in pairs, and borne on a particular eminence, like those of the 
aquatic tubiteles. 
Clubiona, Latr., 
Are scarcely distinguished from the following subgenus, ex- 
cept in this, that the length of the external spinnerets are but 
little different, and the line formed by the four anterior eyes, is 
straight, or almost straight. They form silken tubes, serving 
them as an habitation, and which they place either under 
stones, in clefts of walls, or between leaves. The cocoons are 
globular. 
The Spiders, proper. (Aranea), 
Which we had at first designated under the generic name of 
tegenaria, preserved by M. Walckenaer, and to which we 
reunite his agelena, and his nyssus, have their two upper 
spinnerets remarkably longer than the others, and their four 
anterior eyes disposed in a line curved backwards. 
They construct in the interior of our habitations, at the 
angles of walls, on plants, hedges, and often on the edges of 
roads, either in the earth, or under stones, a large web, nearly 
horizontal, and at the upper part of which is a tube, where 
they remain without making any motion. 
Now come the nayades of M. Walckenaer, or our aquatic 
tubiteles, and which compose the genus
