which, was displayed in the tube of N. Eleanora. I regretted that I was unable to continue my observations on this captive spider, as it would have been interesting to know how long she would have lived contentedly and in good health under the conditions described above, but I left Mentone at the end of April, and was unable to take her alive with me to England. When removed from her nest in the pot on April 12, she appeared in perfect condition, and I placed her in a hole which I made for her among some stones in a garden at the back of the house, hoping to find her again on my return to Mentone in the autumn; this hope was, however, not destined to be realized.
I shall, however, have occasion to speak again of the young captives of this species (N. Eleanora), in the concluding remarks which will follow these detailed accounts of the nests and their occupants, when the behaviour of captive trap-door spiders generally will be treated of.
The next type of trap-door nest is one to which I have found it difficult to assign a descriptive name, and I am compelled for the present to speak of it as the Hyères double-door branched wafer nest.
One of its most distinctive features is found in the shape of the lower door, fig. F 1, Plate XIV., and figs. A 1, A 2, Plate XVIII., which may be said to be double, presenting two crowns, one of which fits into the main tube and the other into the branch, but I could not see my way to employing this character in naming the type. The nest is, however, quite distinct from all the others, and is inhabited by a new species of
