Note 108 — EXPLANATION OF PLATES.

While these pages were passing through the press (Hyères, Oct. '74), I have had an opportunity of examining 17 additional specimens of N. congener. I learn from this that the pattern represented on the caput in fig. A 5, does not accord with that in the majority of adult specimens, being usually less defined and composed of three converging bands. Mr. Pickard-Cambridge's description (p. 293 below) is, however, quite correct. I may mention that three spines were present on the patella (genual joint) of legs III in 16 specimens, the 17th specimen having but a single spine.
