428 Dr. Heinekeu on the Reproduction of 



1. 



Epeira fasciata. The first limb was removed on the 23d of July, and 

 the last on the 3d of August. The remaining legs were, then, the second 

 and last on the left side, and the last but one on the right side. 

 Aug. 4. Full two-thirds of the web torn away. 



5. Web thoroughly mended.* The spider maintains the same 



position and attitude as before mutilation, and has in every 

 respect the manners of a weaver. 



9. Disappeared. 



2. 

 Ep. fasciata. First limb removed July 24, last August 1. 

 Aug. 3. Web torn. 



4. The spider has disappeared. The web is not mended. It had 



frequently during the progressive mutilation mended the 

 web, and always maintained the character of a weaver. 



3. 



The same in every respect as 2. 



N. B. The above were in a garden and at liberty. "The following 



were in the house and confined. 



4. 



July 10. A tube-making spider caught with two middle legs off". On 

 the 24th the number of legs was reduced to three, and it 

 was put into a large clean goblet with a flat bottom and a 

 cover. On the afternoon of the same day a sufficient num- 

 ber of filaments were drawn across the bottom of the glass 

 to hamper, but not to catch, a lively unmutilated fly : the 

 spider remaining quiet and crouched like other web- 

 makers, and instead of facing, or attempting to spring 

 upon the prey like a hunter, running from it when they 

 accidentally came in contact. 



25. Fly entangled and killed. 



26. Another fly introduced : still no attempt at hunting. Is un- 

 able to climb up the glass — A twig put in. 



* The Ep. fasciata makes a very large, firm, geometrical web, of laborious 

 construction.
