There seems to be much confusion respecting this 
species ; I believe it to be a collection of tolerably "well- 
marked forms, including G. minax, jlavomaculata, &c., 
which may perhaps be varieties of one species ; Koch says 
that he formerly believed it to be a Javanese form (Arachn. 
Austral. l,p. 8), and Doleschall identifies it with a species 
which I believe to be the G. kelva of Blackwall.

We have one shrivelled example of Avhat may be tliis

much in colouring.
