Amongst tlie Jiiateiial collected by Di-. Tliog. Bancroft, at Eidsvold, 

 Queensland, there is a very pretty male spider, wliicli, whilst being a 

 true Ctenizid, differs from all Australian forms included in that series 

 liitherto examined and studied by us. It has a rastellum and three 

 claws, but like species of (he genus Jhtchios, Sim. (Brazil), and ScnJidoy- 

 natJius, Karsch (Ceylon), there is no tibial apophysis on legi.; again, 

 like liermacha, Sim. (Central America and South Africa) the inferioi' 

 tarsal claw is very rudimentar}'. It would seem, therefore, that a new 

 genus is necessary foi- its leception. It may also be necessary heieafter 

 to establish a new group for its convenience since it dilfei-s from all 

 Nemesids in having the thoiacic fin'ea straight instead of recurved. 

 However, until such time as additional matei-ial, including male and 

 female examples, shall have been collected, it will be bettei' to include it 

 in the Nemesiae group. Accordingly it is there so placed.
