I had never raised the thought of a "community" to Account for these groupings, for I knew that the species represented therein had the solitary liabit characteristic of Orbweavers. Another example fell under my observation, which more closely resem- bled those cited by Darwin and Azara. I once found on the slopes of Brush Mountain, Pennsylvania, just above the banks of the Juniata River, a large colony of the young of Uloborus plumipes. Their pretty horizontal webs were spread over the toi)s of a clump of low laurel bushes covering an area ten or twelve feet in diameter. It needed onty increased size and more vigorous spinningwork to establish a close correspondence between the appearance of this brood's en- campment and the " community " of La Plata. A case somewhat similar to this is recorded by Vinson as in the African island of Reunion.' In the great net of the Epeiroids, stretched between trees of Panda- nus, one might count the inmates living in colony (en famille), and in real harmony. There were found spiders of all ages and sizes; there were Nephila nigra and N. inaurata, messmates so hearty; and there came the Linyphia) to estab- lish themselves upon these huge snares in order to glean the petty prey. It is Vinson's opinion that these little aranead parasites sought the protection of the largo Orb- weavers by suspending themselves thereto in innumerable quantities, in order to avoid the birds and other enemies. Probably the " seeking" consists in the simple and natural fact that the young were bred in the neighborhood of the webs, and continued where they were hatched, avail- ing themselves of the spare spaces in the webs of their gigantic kindred, precisely as the little Furrow spiders of our f
