. American spiders and their spinningwork. A natural history of the orbweaving spiders of the United States, with special regard to their industry and habits . mber of radii crossed at regular intervals by con-centrics after the manner of the common orbweaving spider. The radiiwere about one-sixteenth inch apart at the bottom or circumference of thedome. The concentrics extended entirely and with equal regu-larity to the summit. They did not cross the radii in circularlines, but presented that notched appearance which characterizesthe notched zone in the ordinary webs of Orbitelarite. The meshes formedby the radii and spirals had thus much the shape of the meshes in a fish-ermans net. The diameter of the dome was from seven to eight inchesat the base, and the height nearly the same. It was suspended in themidst of the retitelarian TheDome like character, which thor icate structure, and per Beneath the dome, removed, was a light sheet meshed by wavThe Cur- j^ jj.^.j .^ ^^^i^tamed , , Floor. ^^?^^ supported, and of which itcurtain, by silken threadsexactly to meet this purhave been simply the colweb, which had been stripdoned in order to con.

Of the many specimens of spinningwork which I have studied, I havenever seen one quite so beautiful as this. It was with real regret that sucha rare piece of spider architecture was destroyed, after it had been sketched,in order that the architect, herseK one of the most beautiful of herkind, might be collected for the cabinet.
