It was made be- neath a stone, and when that was lifted up the spider, Lycosa saccata, showed within as at Fig. 175. The roof of her den was broken off by lifting and is shown in inverted position at Fig. 176. The use of this special eocooning den is common with Lycosids; but some species, and probably all at times, live within the home burrow while carrying their cocoons. This is the habit of Lycosa arenicola, which may often be seen on her turret with her egg ball at her .spinnerets. (See Vol. I., page 314, Fig. 289.) There is no flossy wadding within tlie cocoon case of Lycosids, as is common with Orbweaving spiders. Indeed, such a provision for the com- fort and safety of the brood appears wholly unnecessary in the case of younglings whose egg life is so brief, and of a mother who carries her young about with her, and thus gives them the advantage of her personal protection and care. The Orbweaving mother generally dies within a few days after ovipositing. Personal protection of her offspring is therefore im- possible, and the period of development is often greatly prolonged. Nature lias taught her to provide for them the necessary covering of a warm, flos,sy, silken blanket beneath which they may outlive the changes of weather. In the case of Dolomedes, the cocoon is carried by the mother until shortly before the period of hatching, when it is generally deposited within a pretty nest composed of leaves drawn together and lashed at the edges into the form of a tent. (See Fig. 177; also Vol. I., Fig. 339.) Within this a mass of in- tersecting lines is spun, upon which the cocoon is hung. After hatching the spiderlings occupy the
