1896.] SPIDERS FROM THE LOWHR AMAZONS. 747 
of legs, and pedipalps rich brown. Underside of legs clothed 
with sandy yellow-brown hairs. Inner margin of coxa of pedipalp 
and outer margin of fang-groove fringed with fiery-red hairs. 
Protarst and tarsi i. and ii. entirely, 3 of protarsus ii. and whole 
of tarsus, 4 of protarsus iv. and whole of tarsus, furnished with a 
dense pad of scopular hairs. Tarsi i., ii., ili., and iv. broad, 
spatuliform, but iv. much less so. Upperside of legs clothed with 
rich chocolate-brown hairs on femora, becoming more rufous along 
the four distal segments. Hair on legs short (not long, as in 
Avicularia). Patelle of legs i. and ii. and pedipalp slashed with 
four narrow lines of short, pale, sandy-grey pubescence, central 
pair confluent towards apex of segment. Tibia i. and ii. of pedi- 
palp with two widely separate pairs of pale lines of pubescence ; 
each pair very narrowly separate. Protarsi i. and ii. and of pedipalp 
with fine, short, central, pale basal line. Legs iii. and iv. exhibiting 
a somewhat similar but less conspicuous arrangement of pale lines. 
Femora of all four pairs with two faint dorsal and a pair of lateral 
yellow lines on the outer side, the latter obsolete on iv. 
Carapace longer than broad, narrow, in proportion of 20: 16, 
distinctly gibbous behind eye-tumulus. Central fovea deep, trans- 
verse, slightly procurved. Lye-tumulus twice as long as broad. 
Anterior row of eyes only a little procurved. Fang-groove armed 
with a single row of short conical teeth along outer margin, its 
floor towards base studded with minute granules. Sternwm with 
four pairs of sigilla visible: 1st at base of labial plate, 2nd marginal, 
3rd submarginal, 4th remote from margin. 
Labium quadrate, a little longer than broad ; distal third entirely 
studded with minute cuspules. Coxa of pedipalp almost twice as 
long as broad ; inner distal angle slightly produced, obtusely conical ; 
inner basal angle studded with minute cuspules ; inner basal disc 
with a few more scattered cuspules. Legs of fourth pair shorter 
than those of first pair. Patella and tibia i. equal to length of 
carapace. Tibia and patella iv. shorter than carapace. Tarsus of 
pedipalp with one, of legs i.,ii., iii., and iv. with two small stout 
hooked claws, their inner central edge armed with five minute 
denticles. Spinning-mamille four; posterior pair trisegmental, 
second segment shortest; the whole three segments taken together 
not longer than width of sternum. 
The habits of Santaremia pococki are well known and have been 
for years. So long ago as 1879, Mr. Bates mentions the large 
spiders found near Para, forming long silk-lined tubes in the sandy 
soil near Nazareth. 
I was unable to secure any specimens from Para myself, but met 
with abundance at Santarem and at several other places on the 
river, Monte Alegre. 
At Santarem, their burrows, eighteen inches long, were most 
numerous along the banks of the waggon-track running across the 
sandy campos to the forest. Here at any time of day, though 
more especially at night, the females might be seen sitting at the 
entrance of the tube, which was trumpet-shaped and eee over-
