Other genera not before recognized in a fossil state, but here recorded from American strata, are Titanoeca, Tetragnatha, and Nephila. To enter into details, seventy-one genera of spiders have been described from the Tertiaries, sixty-six from Europe, and thirteen by Scudder from America, eight genera being common to both. Of these seventy-one gen- era, thirty-seven are counted extinct, thirty-five from Europe, and two from America, none of these extinct species being found in both countries. The European genera are, as may be supposed, largely composed of amber species, no less than fifty-two, including thirty-two distinct genera, being confined to amber deposits, besides others which they possess in common with the stratified beds.^ Palpipes priscus ^ has been so long regarded as a Jurassic spider that I have alluded to it in this chapter, but that it is not a true spider, but ' Thorell, Kuropean Spidei-s, pages 223-233. ^ Scudder, Tertiary Insects of N.
