fix feet formed for running ; a mouth fur nifhed with four 
palpi ; two of which are fetaceous, and two capitated. 
The body is covered with imbricated fcalcs ; and the tail 
is terminated by briftly appendices f .

and damp houfes. In the former, they retreat under 
mouldy boards or ilag-ftones ; and in the latter, they aie 
feen about window fafhes, and old boxes that have re- 
mained for i'otne time in a humid fnuaticn. When their

ty, that they are but feldom caught ; and when that hap- 
pens, they are often deftroyed, being, from their foftnefs, 
ealily crufhed.
