 one or two special distinctions observed between the two male examples examined. It should however be noted that in one (the one captured behind a stone wall) the ocular area was slightly narrower in proportion to its length, and the interval between the eyes of each lateral pair rather less.

Adult male, length 6-3/4 lines (14 mm.), female adult, length 10-1/2 lines (22 mm.).

The examination of an adult example of each sex of this spider received from M. Simon, by whom they were found in Corsica, leads me to conclude that we have here the true N. meridionalis, Costa, as certainly at least as it is possible at present to identify the species by the insufficient description and figures given by this author.

The eyes appear to be less closely massed together than in N. Manderstjernæ, but in other respects no particularly tangible difference is to be noted; the interval however between the eyes of each lateral pair is perhaps rather greater. Between the male and the female of the present species there is a decided difference in the relative position of the eyes. In the female the fore-centrals are nearer together than each is to the fore-lateral on its side, while in the male, the
