. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. SPINNING ORGANS OF EVAGRUS. IO9 place and fifteen feet away not a spider is to be found, from which we may conclude that the young do not scatter much. The web is a very primitive structure, containing no viscid threads and is hardly more than a thin irregular sheet woven on the ground and attached to twigs, leaves or the rock itself. There seems to be no definite form of nest but simply an irregular sheet of threads. The cocoon of Evagriis is somewhat conical or cup-shaped as shown in Fig. 5, which figure also gives the relation of the. s size of spider to that of cocoon, being a sketch of a spider only a short time after she had finished her cocoon. The cocooning process was seen only once and that time the basal piece had been woven before direct observations began. The base, which was woven first, consists of the cup-shaped lower portion. A short time after it was finished, the spider was closely observed during the remainder of the process. At 2:55 P. M. May 4, the spider placed her epigynum across this base, and discharged from her genital aperture a large yellowish drop of viscid fluid, which remained attached to her for some time, while the ova were dropping into it. At 3:15 P. M. she freed herself from this drop and immediately began to spin the cover. She did this, in which process both pairs of spinnerets were used, by standing with her legs and palpi on the margin of the base, and sweeping her spinnerets from side to side over the egg-mass, never at any.
