In Nos. 1 , 2, and 8, Spider was sitting in centre of web, head downwards ; in 
No. 6 on the under side ; and in Nos. 4, 5, and 7 it had a nest under a leaf ; and in 
5 and 7 there was an open segment in the snare and a trap line to the nest. However, 
in No. 7, 1 believe the open segment must have been caused by an accident, as there 
were 28 rays on the upper side and only 26 on the lower, and some of the spiral threads 
were carried partially across open segment up to a leaf ; also, Spider was in centre of 
web when I first saw it. 
The rays mostly meet in a central ring, {-^^ inch in diameter, but in two snares, 
Nos, 5 and 8, they met in a reticulation. The snares were made near the ground in low 
bushes. The Spider in No. 8 snare when disturbed stretched out its legs after the manner 
of Titragnathti txUnm Liim. I also noticed that this species of Spider has the power 
of darkening dow^n its brilliant colouring when frightened. The colour returning 
when it is dead. 
When living it is of a brilliant golden-green colour, and is found in all parts of the 
Malaysian Archipelago.
