 which the city stands. We subsequently found these nests in tolerable abundance in a deep shady lane near a restaurant called Mon Répos, on the same side of the river, but rather farther up.

Here the hedge banks were high, and the soil was composed of a fine even-grained loam of great depth, which permitted the spiders to carry their tubes very far down, some of them attaining a length of 15 inches.

This made it very difficult to follow them throughout their whole course and so to assure oneself of the real structure of the nests, but I succeeded in doing this in twelve instances.

In every one of these I found the tube cylindrical and unbranched throughout, and destitute of any trace of a lower door.

This deficiency alone distinguishes the present type from that to which the nest of Nemesia Eleanora belongs; the latter being of the double-door and the former of the single-door, unbranched wafer type.

But perhaps it may be asked whether it is safe to assume that because twelve examples of this nest were found to correspond in structure, and were tenanted by the same occupant, that therefore all the Bordeaux nests in which this particular spider might be found would present similar peculiarities.

I greatly hope that other naturalists will put this question to the test of actual investigation on the spot, but I do not hesitate to assert my conviction that this will prove to be the case.

The result of my experience among the nests of the other Nemesias, scores of which I have carefully examined in many widely separated localities, shows
