hairs, glossy, and brownish black. Plates of the spiracles dull brown. 
Some individuals have an obscure series of angular lines of a brownish 
hue, whose vertices are directed forwards, extending along the middle of 
the upper part of the abdomen. 
Males of this spider, in a mature state, were found on rails in the township 
of Crumpsall, in November 1836.
