326 Mr. R. I. Pocock on Arachnida and 



A single female example was obtained by Prof. Sollas. 



The only other species of this genus, namely T. elongata, 

 was described from Sumatra by Silvestri. The description of 

 elongata applies to Sollasii except so far as colour and size 

 are concerned, T. elongata being described as rufo-ferruginous, 

 with pale antennae and legs, and as being 28 millim. in length. 

 Thus, whatever may be the value of the colour-differences, 

 there can be no doubt that elongata is, at all events, twice 

 the size of Sollasii.
