Note 143 — SUPPLEMENT TO TRAP-DOOR SPIDERS.

This spider was described by Mr. Pickard-Cambridge at p. 101 in Ants and Spiders, under the name of N. meridionalis, Costa. This name has now to be abandoned for reasons given in full by Mr. Cambridge at p. 283, below. It would appear that a spider discovered by M. Simon in Corsica corresponds more closely with the N. meridionalis of Costa than our spider of the Riviera does. Moreover, since Ants and Spiders was written I have had the good fortune to obtain at Mentone four male examples of our supposed meridionalis, and these prove to possess the same characters as those assigned by Prof. Ausserer to a male spider which was captured at Nice, and named by him N. Manderstjernæ. This specimen is now in the possession of Dr. L. Koch, to whom I am much indebted for having kindly entrusted it to me for examination. This enabled Mr. Pickard-Cambridge to assure himself of the specific identity of his N. meridionalis with N. Manderstjernæ, which latter name it must for the future bear.
