CHAMBERLIN: ARACHNIDA of PERUVIAN ISLANDS. 37 
e3'e tubercle with two long submedian setae and a shorter one each side of 
this pair in the type. Mesal surface of chelicerae with strongly develop- 
ed stridulating ridges which extend below the middle. Third tooth of 
dorsal finger of chelicera greatly reduced, the fifth tooth as large as or a 
little larger than the fourth. Lateral plates of the rostrum shorter than 
the dorsal. Metatarsus of palpi beneath with numerous furcate setae 
and also with furcate setae above with fewer long and short ordinary 
setae. First legs without claws. Tarsi of all legs only one-jointed; with 
long paired spines beneath which project out laterally. Metatarsus of 
legs II and III with a series of three long, slender spines above in dorso- 
caudal position. Tarsus IV six or more times as long as thick, and distal- 
joint of femur IV more than four times longer than high. Plate of ectal 
malleoli typically near two and two-third times as wide as high. Last 
abdominal segment circular, the anus a symmetrical vertical slit. 
Falls in the group Daesiinae, apparently near the genus Gnosippus 
of Palestine and Egjq^t.

PI. 4, fig. 3. 
Cephalothorax dusky brown with a median longitudinal pale stripe. 
Ocular tubercle black, with no median pale line. Chelicerae fulvous, 
smoky above and over upper part of ectal side; tips of fingers and teeth 
dark. Lower finger of chelicera with two large teeth and an intermediate 
much reduced one, the first tooth larger than the third. Upper finger 
with ten teeth along outer edge; of those the third is much reduced and 
the fifth a little larger than the fourth; the sixth, eighth and tenth teeth 
much larger than any others, the seventh and ninth reduced and of near- 
I3' same size as the intermediate tooth of the lower finger. Metatarsus of 
palpus armed along ventral edges with spines; with rather sparse long 
and short setae above and below and also with very numerous furcate 
setae of which the ventral ones average somewhat longer than the dorsal. 
Metatarsi II and III with three spines on caudal side above, one at distal 
end beneath, between which and the distal one of the dorsal series there is 
a third distal spine, on the second legs at least. Metatarsus IV with i -{- 
1+2 spines. Legs bearing simple and furcate setae, the latter longer 
and more numerous on proximal joints as usual, and on tibiae and meta-
