Two adult females of a Spider, which I feel pretty certain must 
be referred to this species, were taken by myself at Breves and 
Para, and are now in the British Museum Collection. The spines 
on the legs are very long in comparison with those of allied 
genera.

canta apical spine beneath. Tibia i. with four paired spines

the diameter of the segment. Posterior row of eyes recurved ; 
eyes subequal, centrals one diameter apart, two and a half from 
the laterals, which are set on a low tubercle. Anterior row

3 2 .—Colouwr. Carapace dull yellow-brown, with two longi- 
tudinal dark brown bars on each side of the pale central line, the 
whole being almost entirely clothed with yellow-grey scale-like 
hairs. Margins of carapace reticulated with fine dusky lines. 
The anterior portion of the brown bars presents within their 
margin a narrow elongate accent-like pale mark. Abdomen pale 
yellow ; ; dorsal avea with a broad longitudinal dark brown (some- 
times paler) foliated band, becoming narrowed towards the 
spinners, from the centre of whose lateral margin, on both sides, 
issues an oblique interrupted lateral bar. The centre of the 
foliated band is occupied by a pale lanceolate band, much attenu- 
ated towards the spinners, its basal portion again occupied by a 
broad lanceolate dark band, scarcely reaching the centre of the
