distinct fi-om any of its congeners. My friend, Di-. R. Piilleine, 

 of Adelaide, being in Sydney on a visit, I sliowed it to liim, and 

 his conclusion coincided with mine. Dr. Pnlleine lias collected 

 more Australian Aviciilaridae than anyone else, and certainh' 

 possesses the largest and best collection of our native trap- 

 door spidej's that has ever been brought together, so that liis 

 advice and support upon questions in respect of species of tliis 

 family is of decided value. 



The studei^.t upon perusing the description given below, 

 together with the accoinpanying fignres, will readily detect the 

 points wherein this beautiful and strikingly mai'ked spider 

 differs from species pi'evionsly described and known. 



Mr. H. H. Burton Bradlej' was the first Australian natural- 

 ist to study our endemic Araneidae, and I have therefore much 

 pleasure in dedicating the species under discussion in liis 

 honoui'.
