ADDITIONAL PSYCHOLOGICAL NOTE UPON THE" 

 GALLERY SPIDER. 



Bv C. H. Turner. 



Example XXXV^ E. — After my last paj^er had been print- 

 ed, this spider made a unique addition to its web. At a hei.i^ht 

 of about five inches above the main sheet of the web [see Ex. 

 XXXV, D, supra, p. 107], the spider constructed a funnel- 

 shaped web. The circumference of this web was attached to 

 the sides of the jar and the apex was directed downwards. In 

 form this accessory web was a true cone. It was a sort of pyra- 

 mid-shaped body, composed of several unequal flat surfaces. 

 It was fastened to the lower web by tension cords. Its apex 

 was about an inch above the lower web. Snares were abund 

 ant, but there was no gallery This addition to the web con 

 verted it into a miniature model of a lobster pot. The spider 

 usually rested in the gallery of the lower sheet. Every fly that 

 fell upon this upper sheet was doomed to die. Every struggle 

 carried it nearer the apex of the funnel. Sooner or later, it was 

 sure to fall into the trap below. There it was at the mercy of 

 the spider. 



There was no obstructions to prevent the flies escaping by 

 the same opening which they entered ; but I have observed nu- 

 merous flies tumble into the web and not one thought of escap- 

 ing by that opening. Whenever a fly was so fortunate as to be- 

 come disentangled from the lower sheet before being captured 

 by the spider, it was sure to make for the highest portion of the 

 trap. There, hemmed in by the web on all sides, it became an 

 easy victim. 



There is another point I wish to add here. In many of the 

 webs constructed by my imprisoned spiders, the gallery hid two 

 openings. One of these openings led on to the main sheet, 

 while the other led to the sand below. 



Eor a long time I was at a loss to know what the spiders 

 did with the remains of the dead flies. Although the spiders
