Heteropoda, Micrommata, ete. The thick scopula under the tarsus and meta- 
tarsus of these genera is absent in Selenops, which genus thus is distinguished 
not by its peculiar position of the eyes alone. 
It is possible that this genus may have been created already by 
LATREILLE, in the 2™ Edit. of Nouv. Dict. d'Hist. Nat., which I have not 
had the opportunity of consulting (Conf. Durour, loc. cit). In his later 
works however LATREILLE calls it: ” Selenops DUFOUR."

Artamus being the well known and accredited name of a genus of 
birds, so named by VIEILLOT as early as 1816, I have been obliged to give 
the spider-genus Artamus a new appellation. 
In this and the two following genera, the hairs of the claw-tufts 
have an appearance quite different from that presented in any of the genera 
of the family, we have as yet described: these hairs are in fact beyond all 
comparison shorter and broader, flattened, spade-like or feather-like, and far 
less numerous (especially in Thanatus). The claws are often shorter, espe- 
cially in Thanatus, but of the same form; the teeth usually far more nu- 
merous on the inner than on the outer claw, in Philodr. aureolus, for inst., 
about 5 on the outer and about 14 on the inner claw; in Thanatus oblon- 
gus about 3 on the outer and about 10 on the inner; but in Zh. formicinus 
about 5 on the outer and 8 on the inner. The number of teeth on the 
claws is here, as usual, frequently very different not only on the different 
pairs of legs of the same individual, but on the same pair in different in- 
dividuals of the same species, and accordingly the number observed by me 
in the various specimens that I have examined, frequently differs considerably 
from that given by OHLERT.
