On EUROPEAN SPIDERS. 135 
As regards our limitation of this genus, we refer to what has been 
said of the preceding genus, or Histopona. — The superior tarsal claws 
in 7. denticulata or lycosina are of the form usual in the family, but not 
particularly strong, pretty regularly curved, with about 10—12 comb-teeth 
gradually increasing in length, the outermost pointing forwards and diverging. 
The inferior tarsal claw has only ‘wo teeth. In a few other species (among 
which is 7: vestita or ferruginea C. Kocn) I have also found only 2 teeth 
on that claw. 
Gen. 14. HADITES Keryseru. 1862. 
Deriv.: (ys, Hades. 
Syn.: 1862. Hadites KExsERL., Beschr. ein. neuen Spinne aus d. Hóhlen v. Lesina, p. 3 (541). 
Type: Hadites Tegenarioides KEYSERL. 
Of this remarkable, blind spider, which has hitherto been found only 
in the subterraneous caverns of the isle of Lesina, Count KEYSERLING has 
kindly presented me with a female specimen. — The superior spinners are 
very long, two-jointed: the first joint is more than double as long as it is 
broad, and somewhat longer than the inferior, thicker spinners; the 2™ joint 
is not so thick as the first, but equally long, conically pointed at the ex- 
tremity, covered on the underside with very long spinning-tubes; on the 
apex of the joint a similar, very coarse spinning-tube is situated. Such a 
tube is found also at the apex of the slender intermediate spinners. — The 
palpal elaw is weak, pretty regularly and slightly curved, with about 8— 
10 gradually increasing, pointed comb-teeth directed forwards. The tarsal 
claws are of the form usual in the Agalenine, somewhat weak, with about 
12 long, pointed comb-teeth directed forwards; the inferior claw is small, 
with 3 long, pointed teeth. — KEYSERLING has found only 7 or 8 teeth on 
the superior and 2 on the inferior tarsal claw (loc. cit., p. 5).
