In other words, the Theraphosid cocoon is, first, round or ovoid; second, is carried about with the mother, attached to her body, or kept under her care; and, third, the young for a period longer or shorter remain with their mother. The affinity between these two great groups of araneads is also marked in their nesting habits; both burrow into the ground a cylindrical tunnel or shaft, within which they domicile, sometimes lining it more or less completely with silk. IV. Passing now into the group of Wandering spiders, we reach the co- coonery of the Citigrades, and here find little variety in structure, with scarcely an exception. The cocoons of this tribe are round balls without any interior furnishing, which are carried by the moth- er within her jaws, as in the case of I)ol- omedes, or lashed to the spinnerets, as with the Lycosids and most other species.
