destitute of teeth; the palpal claw has 3 or 4 small comb-teeth close to 
the base. In 7: (A.) picta the claws are somewhat shorter, with about 8 
teeth on the superior tarsal claws, in 7! (A.) leopardus with 7: in this last 
species I have seen one tooth on the inferior claw, and a very small point 
just behind it, at least on the 4" pair of legs. — Also in 7. intricaria C. 
Koch the free extremity of the claws is very long; the superior tarsal claws 
have but 4 parallel teeth, of which the three outer are very coarse; the palpal 
claw has also 4 teeth, the innermost much smaller than the others. This 
species is also distinguished by the trapezoid formed by the 4 posterior 
eyes being twice as broad behind as in front, whereas in the typical spe- 
cies of the genus it is only 14 time as broad behind: moreover the anterior 
row of eyes is longer in comparison with the middle row than in the other 
species of the genus. But it does not appear to me necessary on account 
of these deviations to form a new genus for 7. intricaria. | 
T. ruricola has 5—6 comb-teeth on the superior tarsal claws; the 
inferior claw is without teeth; the palpal claw has four gradually increasing 
teeth. In this species the spine, which is so frequently met with among the 
Lyeosoidz at the end of the male's palpus, is pointed and somewhat curved 
at the extremity, and thus very like a toothless claw; it is absent in 7. 
terricola 'THOR., in which species the female’s palpal claw is generally 
furnished with 2 coarse teeth, and a 3" small tooth behind them.

Type: Pirata piraticus (CLERCK). 
The name Pirata SUND. has right of priority in preference to Po- 
tamia C. KocH, which latter moreover had been already several times ap- 
propriated, before KocH in 1848 applied it to the genus before us.— Vid. p. 37. 
P. piraticus has about 7 long teeth on the superior tarsal claws, and 
one fine tooth with the rudiment of a second on the inferior claw. The
