OF THE ORDER ARANEIDEA. 245 
July, 1846, one of them was pierced by the fangs 
of her opponent on the underside of the abdo- 
men, near the spinners. A transparent colourless 
fluid oozed from the wounds for many minutes, and 
ultimately coagulated ; but the spider seemed to ex- 
perience little inconvenience from the injury, being 
lively in its motions and preying eagerly upon the 
insects with which it was supplied. The tempera- 
ture at the time was 76°, and the atmosphere was 
highly electrical. 
A female Ciniflo atrox was bitten by an exasper- 
ated female Zycosa agretyca near the middle of the 
cephalothorax, on the 29th of July, 1846, the tem-

retained its hold for many seconds, and on quitting 
it voluntarily a transparent colourless fluid flowed 
from the punctures and coagulated. The wounded 
spider, apparently regardless of the injury it had re- 
ceived, spun a web with which it long continued to 
ensnare its victims. 
On the same day, the mercury in the thermometer 
denoting a temperature of 75°, a female Epeira 
diadema, in a violent struggle with a female Celotes 
saxatilis, pierced her abdomen in the medial line of 
the dorsal region, about a third of its length from the 
spinners. The wounded spider did not exhibit any 
marked symptoms of distress and speedily resumed 
its accustomed habits.
