neiii Australian Spiders. 309 



specimens have come to hand at the British Maseura, from 

 Western Australia and Tasmania respectively, of this inter- 

 esting family, which, as they are both new, I propose \o 

 put on record. 



I have already described several species of Aganippe, from 

 South Australia and one species which — partly from a distinct 

 modification in tlie shapeof theeye-spxce, but more particularly 

 from an alteration in the shape of the spurs at the anterior 

 end of the tibia of the first pair of legs (this being a character 

 which is usually very persistent) — I rather thought should be 

 placed in a separate genus (Blakistom'a). 



In the present specimen (a male from Roebourne, on the 

 N.W. coast of Western Australia) the eyes are distinctly 

 intermediate between the two above genera : the apophyses ou 

 the tibial joint of the palp are of an Aganippe character, while 

 the tibial spur of the first pair of legs conforms more nearly 

 to the Blakistonia pattern. Until we have more material I 

 add it to the Aganippe series. 



The specimen from Tasmania was sent to Dr. Peckham in 

 America, and by him forwarded on to the British Museum. 

 It is an associate of the New Zealand forms of the genus 

 Arham'fin, L. Koch, but, from the difference between their 

 tarsal claws and those depicted by L. Koch of his type species 

 from Queensland, the type specimen of which is not known, 

 I have always had considerable doubts as to whether they 

 can be considered to come within the bounds of that genus, 

 to which their eyes conform.
