TuRXER, Notes Upon the Gallery Spider. 99 



in the web are very suggestive. Why may not bits of white- 

 wash falUng into such a web as is described in example X, have 

 such so stretched that web as to produce the one described in 

 example XL This possibiUty is strengthened by the following 

 fact : By dropping bit after bit of wood into a web of the type 

 described in experiment X, I was enabled to produce a web of 

 the type described in example XI. 



I have, however, seen a few webs where the funnel shape 

 was something more than a transformation by stretching of an 

 originally slightly bagging web. The following example is an 

 illustration. 



Ex.AMPLE XII. — Between two vertical and one horizontal 

 log. Main sheet funnel shape, the apex of the funnel being 

 vertical. Gallery vertical, at the apex of the funnel. Guard 

 web absent. Snares very abundant, forming a loose horizontal 

 network. 



Next in number to the triangular webs come the rectangu- 

 lar webs. The rectangular webs vary in shape from perfect 

 squares to very long rectangles. The sides are sometimes 

 straight and sometimes curved. Occasionally more remarkable 

 variations are encountered. 



Example XIII. — Location : crack in an old tree trunk. 

 Main sheet nearly horizontal, attached on all sides to supports. 

 A short distance above the main sheet there was a parallel sec- 

 ondary sheet. This sheet completely hid the gallery from above. 

 This secondary sheet was nearly as large as the main sheet. 

 Gallery at one corner in a crack. Guard well on one side only, 

 high near the trunk. Snares abundant. 



This secondary sheet is an interesting feature. Unfortu- 

 nately I had no opportunity to see the inhabitant of this web. 

 Therefore I cannot say whether it was an individual of the same 

 species as the spiders of the neighboring webs or not. None of 

 the other webs of that vicinity porsessed a secondary sheet 

 above the main one. 



As in triangular webs, so here the main sheet often departs 

 a great deal from the horizontal. Among my notes is recorded 

 one of these inclined webs which contains a noteworthy modi- 

 fication. 



Example XIV. — Location : ledge in stone wall in front of
