very unpleasant sensation in his throat. One very re- 

 markable species (Gasteracantha arcuata, Koch) has two 

 enormous, recurved, conical spines, proceeding upwards 

 from the posterior part of the body, several times longer 

 than the entire Spider. The Drassi are gloomy Spiders, 

 haunting obscure places, and their garb is dark coloured

 mostly pale brown, black, dull red, or grey. The Thomisi 

 are varied in their colour, in harmony with their usual 

 abiding places. Thus, those that spend their lives among 

 the flowers and foliage of the trees, are delicately and

 the vegetation among which it lives, is not agile in its 

 movements, but drops, when alarmed, among the foliage ; 

 it is of a pale delicate semi-transparent sap-green, with 

 the eyes and chelicera red ; there is a large mark on the 

 surface of the abdomen, beautifully variegated with 

 yellow, pink, and black, and margined with dead-white 

 spots; the under surface is green in the middle and 

 opaque white on either side ; the spinneret is pink.
