to the spinners; down its centre runs a narrow dusky 
band, resolved into chevrons, to the spinners. Vulva 
consisting of an anterior transverse-oval area, half its 
diameter distant from the genital rima, with a pair of larger 
oval adjacent dark discs transversely situated on the rima, 
with another pair of small adjacent dark discs longitudinally 
situated and slightly overlapping the larger pair; at this 
point is a pair of dark spots connected with a circularly 
curving duct which bounds the anterior transverse-oval 
area. we we ee ee ee ee we ew ee «eCOndita, Peckh. 
a*, Cephalic area very distinctly yellow, margined round the 
eyes with black; carapace with a broad patch of white 
scales on the posterior-lateral margin. Abdomen very 
similar in pattern to that of S. recondita. Vulva also 
very similar ; forming a transverse-oval area divided by a 
narrow septum into a pair of circular-oval areas, half a 
diameter distant from the rima, with a pair of large dark 
adjacent oval discs transversely situate, and a small pair 
of adjacent oval spots obliquely situate in front of the 
former and slightly overlapping them; these are, however, 
much smaller than in S. recondita, but are similarly con- 
nected by a black spot with a circularly curving duct . . festiva, Peckh.

Legs and palpi pale yellow, with dusky apical and basal annu- 
lation on each segment. Abdomen very pale olive-green, with a 
pale central dorsal scalloped band, broadly dilate behind, above 
the spinners. Vulva consisting of a broad transverse-oval area, 
with a pair of large circular adjacent transverse-oval dark discs, 
each connected by a broad duct with a dark spot near the 
anterior margin of the area; beneath each spot lies an indistinct

2. Carapace brown, cephalic area black, with a broad pale band 
behind the posterior eyes and continued to the anterior margin 
on each side. Legs unicolorous yellow. Abdomen rich brown 
or black, mottled, with a broad pale band encircling the anterior 
margin and continued obliquely down the sides ; posteriorly is a 
large transverse-oval black spot with a pair of pale spots in its 
centre, cut out by a pale band which broadens to the spinners, 
bearing one or more central black spots. Vulva consisting of a 
pair of white auriculoid areas confluent on the central line, with 
a pair of dark oval adjacent discs behind, not quite one diameter 
distant from the rima, connected by aslender duct with a dark spot, 
each spot also connected with the duct which encircles the area . nigriventer.
