Fam. I. OXYOPOIDÆ. 
The spiders of this family, as is known, exhibit certain analogies 
with both Attoide and Philodrominæ, and seem to form a connecting link 
between the Zycosoidæ and these groups. ‘They resemble the Attoide in 
their, comparatively with the Lycosoidæ, broader back of the cephalothorax, 
and frequently display a remarkable similitude with the Philodromin« in their 
whole general appearance, and even in the position of the eyes (compare 
e. g. Peucetia and Eripus). But the Lycosoide are, as is generally admitted, 
their nearest relations, and it is also with them that they most closely agree 
in the structure of the claws. The tarsal claws are however usually longer 
than in the Lycosoidæ, with a shorter extremity and more teeth; the inferior 
claw has, in the species that I have examined, two or three teeth. The males 
have no claw at the end of the palpus. — To this family I refer two Eu- 
ropean genera, Peucetia and Oxyopes.

Type: Peucetia viridis (BLACKW.). 
The type of this genus is Oxyopes littoralis Sim. (loc. cit), but this 
species appears to me to be identical with Pasithea viridis BLACKW. (loc. 
cit), which was first by BLACKWALL aggregated to the Laterigrade, but 
afterwards ?) rightly to the Citigrade. — P. viridis differs from Oxyopes, 
to which genus it is referred by SIMON, not only in the position of the eyes,
