Whether Dolophones notacanthas (Quoy et GAIN.) ?) really belong to the 
Orbitelarie and Epeiroide, as SIMON thinks,?) appears to me tolerably doubtful. 
The New-Holland genus Celenia 'THOR.,?) distinguished by its high 
clypeus and its long slender anterior pairs of legs developed into a sort of pe- 
des raptorü, the two upper tarsal claws of which are of very different size, 
ought certainly to form a separate sub-family (perhaps a particular family). This 
genus bas 3 claws upon the tarsi, which is said not to be the case with the, as 
it seems, else so nearly related genus T’hlaosoma CAMBR., the species of 
which, according to CAMBRIDGE,*) have only two tarsal claws, and make 
no web, but live "beneath folded leaves.” CAMBRIDGE assigns Thlaosoma 
to the Thomisoide, to which family  Celenia at any rate cannot be 
aggregated. 
WuitE has 5) under the name of Linyphia (Leucauge) argyrobapta 
described a spider taken by DARWIN in Brazil, whieh probably belongs to the 
Epeiroide; at least there is reason to suppose so, in consequence of the 
following notice of the remarkable method pursued by this species in the 
construction of its web, which WHITE communicates from DARWIN'S MSS. 
"Web very regular, nearly horizontal, with concentric circles: beneath, but 
sometimes above, the concentric web, there is an irregular or thin tissue 
of network; the animal rests in the centre, on the inferior surface.”
