Turner, Notes Upon the Gallery Spider. loi 



Gallery horizontal, located in the angle between the logs. 

 Guard sheet absent. 



Here again we meet one of those basket-like webs. [cf. ex- 

 ample XL] In this case, however, the depression was empty. 



Example XVIII. — Location : weeds and logs, near the 

 ground. Main sheet is horizontal and consists of three rect- 

 angles arranged like the lobes of a clover leaf. Gallery in a 

 hole in a log. Guard web absent. Snares abundant. 



Example XIX.— Location : two adjacent vertical posts. 

 Main sheet double. As the posts stood there were two angles 

 between them. These angles were opposite each other. In 

 each angle was located one division of the main sheet of the 

 web. These two divisions were not counterparts of each other. 

 Sheet number one was horizontal and attached to the two logs 

 and a neighboring log. Sheet number two was inclined and 

 was attached to the two logs and to neighboring weeds. Gal- 

 lery common to the two webs, hour-glass shaped and located 

 between the two logs. 



With one exception, this appears to be the most remarkable 

 web that I have ever encountered. It seems as though the 

 builder had been animated by thought similar to those which 

 prompts a school boy to fish with two lines instead of one. It 

 seems as though the spider has learned to kill two birds with one 

 stone. Among the piles where this web was found there were 

 hundreds of webs. There were also numerous places where 

 double webs of the above type might have been constructed. 

 Yet the above example was the only one observed in that place. 

 That spider appeared to be the master mind of the locality. 



About the posts of ancient rail fences, I have occasionally 

 thought that I observed other webs of the kind described in ex- 

 ample XIX. But in no case was I certain of this. 



Next to the main sheet, the gallery is the most conspicuous 

 portion of the gallery webs. Like the main sheets, the gallery 

 is subject to great variation. But usually these varations do not 

 consist of changes in the form of the gallery. I have noticed 

 one case where the gallery was hour-glass shape, [see Ex. XIX] 

 but as a rule the gallery departs but little from the usual conical 

 shape. The variations here are of a different sort. They con- 

 sist in variations in the location of the gallery.
