Doleschail says that "This spider is common in Amboina, constructing a large regular 
snare in dark places in the vicinity of buildings, in the middle of which it holds itself, and 
to which it firmly fastens its flat angular cocoon," 
The snares that I have found in Singapore are perpendicular, and from 5 to 7 inches in 
diameter. 
Rays .., 40—60. 
Inner spiral .,, 7 — 1 1 turns. 
Free zone ... % inch 
Outer spiral ... 40 — ^50 turns. 
Spider seems never to place itself perpendicularly in the centre of snare, but always 
more or less stdeiA'ays, and sometimes has a leaf in the web to which it attaches itself, 
appearing like a bit of dt-bris. As the webs I found were very small and contained no 
cocoons, though most of the spiders were mature, I am inclined to think there mnst be 
two species.
