Tlio Myrinpodsi of the rnitctl Stag's were first stiulit'd by Tlioinaa

 Acadfiiiy of Scieiici's* he (U's<'iil»o(l cijjlitt'en siu'<i«'.s, mostly from the 

 S<»utherii States, wliich he urranp'd in tha '^vnor.i ffulus, Pnlifilrtoniis, 

 l'ol}/.icims^ Cennatia, LHImhiiiM, (hfiptops^ and (hitfthihis. Scatterini^ 

 spciies had already been (h'scribed l)y the earlier Kuropeau naturalists, 

 and even in America one species had been described in ISi'O by Kalin- 

 es(pie under the name of Selista forceps. Yet Say's work will stand as 

 the first of hnportance, reco{,Miizinj;, as it «h)es, a c<msiderable number 

 ot si)ecies. 



After Say's time no species were added to our fauna for twenty years, 

 when lirandt (1841) published from St. retersburj; his Kecueil, consist- 

 inj»: of a re])riiit of a series of papers relating to the Myriapods which 

 he had issued since 1831). Four species from our territory are here 

 des«iil)ed. After Brandt came Newport, who i)ul)lished in 1844 a 

 monograjih of the Chilopoda, in wliich live species were added to our 

 fauna and the genera T/icatops and Scolopocryptops were founded, to 

 which he referred some of Say's species. Three years later (1847) Koch 

 published his "System der Myriapoden", in which a c<uisiderable num- 

 ber of American species were described. The same year ai)peared 

 volume IV of "Apteres," by Baron Walckenaer and I'aul (Jervais, iu 

 which the latter describes tw(j new species from the riiited States and 

 includes descriptions of the species of Say, Brandt, and Newport, iu 

 all amounting to twenty-six species. 



During this period two other papers appeared. In 1853 Charles 

 Girard ]>ublished iu an appendix to the Eeport of Marcy's Exploring 

 Expedition a description of Scolopindm hcros^the large "centipede" of 

 the Southwest, with plate, together with two species of Juliiii supposed 

 to be new. Three years later Sager published brief and indetinite de- 

 scriptions of three new species, giving neither distinguishing characters 

 to his species nor the localities from which he obtained his specimens. 

 The lirst four decades since Say's first publication thus found us with 

 a known Myriapod fauna of about thirty nominal species. 



*An alphabetic list of the literature relating to the Aiiieriean species is appended 



to this lutrodiii'tiou.
