ANCESTRAL SPIDERS AND THEIR HABITS. 453 



fact may be readily seen by comparing Berendt's numerous figures of the 

 well preserved amber spiders with examples from corresponding genera. 

 (See Fig. 373, compared with Figs. 376 and 377, and the full page cut 

 further on.) 



The Florissant fossils are of course not so well preserved, but some of 

 the specimens retain their characteristics with sufficient distinctness to 

 compel the same conclusion. Scudder's figures, as they are displayed upon 

 his plate, might well stand for good drawings of a miscellaneous collec- 

 tion of damaged specimens of our living spiders. Compare his figure of 

 the fossil Orbweaver Epeira meekii, for example (Fig. 375), with our familiar 

 Epeira strix (Fig. 376) or Epeira insularis (Fig. 377).

Turning to the oldest known fossil aranead, Protolycosa anthrocophila 

 R(')iner, we are brought face to face with a si)ecies closely related to exist- 

 ing fauna. (Fig. 378.) Protolycosa belongs to the Carbonifer- 

 Oldest Q^^,g^ being found in the argillaceous slate of Kattowitz, upper 

 Known giiggj., i pjg 379 jg an enlarged drawing, and Fig. 380 is an 

 Fossil" outline restoration by the author. Rt'imer placed the fossil near 

 the genus Lycosa of the Citigrades, which rank among the highest 

 of the araneads. Thorell, on the ground of the extremely coarse and short, 

 strong legs and palps, assigns it to the Territelaria3, which puts it within 

 a closely related group, in which we have found the largest existing spiders, 

 Thcraphosoidaj, the Tarantulas, and such also as possess the highest me- 

 chanical instincts, as Trapdoor spiders. The first apparition of the spider 

 is therefore by no means that of a low example, but one rather which 

 presents a plenitude of faunal characteristics, and gives the possibility of 

 high industrial skill. 



Moreover, Protolycosa is nearly related to a living species. Thorell 

 points out its marked resemblance to Schiodte's wonderful East India genus
