The length of the male of this dark, sombre-coloured spider 

 is four lines, the fomalo being rather larger; it may be recognised 

 easily by the abdomen being thickly covered with mouse-black, 

 silky hairs, which give it a somewhat shining and greasy 

 appearand ; a few coarser, oroct hairs aro also mixed with tho 

 others. It is, so far as I am aware, exclusively a house spider, 

 and is not rare at the Rectory, Bloxworth, where it is found 

 roaming about at night on the walls of tho entrance-hall, stair- 

 case, and passages, as well as in the outbuildings. I havo mot 

 with it in several other localities in Dorsetshire, and havo 

 received it from various parts of England. 



Brassus serioeus Walck, with which Mr. Blackwall supposed it 

 to be idontical, is quito another species.

This spider is of a dark yellowish-brown colour, and tho 



abdomen has often ashiniug, coppory huo imparted to it byits hairy 



clothing. The hinder part of tho abdomen has a longitudinal series 



of indistinct, pale, angular bars on tho upper side, and in front of 



these bars, on the fore part, aro six short linear spots, forming two 



longitudinal, curved, parallel rows, of three spots each; tho con- 



vexitios of the curves are directed inwards towards each other. 



The eyes of the hind-central pair aro placed obliquely, and very 



near to each other, nearer than in almost any other of our
