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. 

 Protarsi and tarsi i. and ii. entirely, | of protarsus iii. and whole 

 of tarsus, | of protarsus iv. and whole of tarsus, furnished with a 

 dense pad of scopular hairs. Tarsi i., ii., iii., and iv. broad, 

 spatuliform, but iv. much less so. TJpperside 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). Patellm of legs i. and ii. and pedipalp slashed with 

 four narrow lines oE short, pale, sandy-grey pubescence, central 

 pair confluent towards apex of segment. Tibice 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 

 j'ellow lines on the outer side, the latter obsolete on iv. 



Oarapace longcjr than broad, narrow, in proportion of 20 ; 16, 

 distinctly gibbous behind eye-tumulus. Central fovea deep, trans- 

 verse, slightly procurved. Eye-tumulus twice as long as broad. 

 Anterior row of eyes only a little procurved. Famj-groove armed 

 with a single row of short conical teeth along outer margin, its 

 floor towards base studded with minute granules. Sternum with 

 four pairs of sigiUa visible : 1st at base of labial plate, 2nd marginal, 

 3rd submargiual, 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-mamillm 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 usually over-
