Observations. Much as the sexes differ from each other, 
I cannot doubt their constituting one species, having repeat- 
edly found them enclosed. quietly in the ‘same silk tube, and 
having always found the males and the females with the 
characters given above. The spots and markings of these 
Spiders are formed by hairs or scales, which have certain 
metallic reflections. The motions of this spider are slow, 
and exhibit caution; it is found usually on trees, and often 
nates under the bark of decaying trunks. The m e 
remarkable for his enlarged, nearly horizontal cheliceres, is” 
à very bold little fellow, always ready for action, and det : j 
ined: to see all things for himself, raising and turi ng h 
„ad towards the object that approaches him, and usually 
Tus "pon his enemy instead of ingloriously retreating.
