ON SOME RARE ARACHNIDS 77 



T. Cajubridgii also differs from the present species in the 

 fact that its palpi and fourth femora are slenderer, the latter 

 being more than two and a half times longer than broad 

 (deep). A further difference exists in the trochanter of the 

 palpus, which in Thorell's species has the anterior part of its 

 inferior border produced into an angular prominence. In the 

 present species this is obHquely truncated. It is unfortunate 

 that the males of neither species are known, as in that sex the 

 flagellum is much modified and extremely different in closely 

 allied species. As regards the present species I hope soon to 

 obtain, describe, and figure the male.
