Although no Spiders have been yet discovered in any rocks so ancient as the Carboniferous series, the presence of Insects in this series, and also of Scorpions, renders it highly probable that the cognate family of Spiders was coordinate with Scorpions, in restraining the Insect tribes of this early epoch, and that it will ere long be recognised among its fossil remains.

The existence of Spiders in the Jurassic portion of the Secondary formations has been established, by Count Munster's discovery of two species in the lithographic limestone of Solenhofen. M. Marcel de Serres and Mr. Murchison have discovered fossil Spiders in Freshwater Tertiary strata near Aix in Provence. (See Pl. 46″, Fig. 12.)
