PALEOZOIC FOSSIL SPORES 



probably a good many specific determi- 

 nations have not been rendered critically 

 enough and this also tends to diminish 

 the value of stratigraphic ranges which 

 can be given now. Nevertheless, some 

 general information may be gained from 

 the ages listed. It has been observed that 

 a good many of the distinctive forms ap- 

 pear in the same relative positions in 

 America and in the European Carbonif- 

 erous (Schopf, chiefly unpublished data) 

 which gives promise of future assistance 

 in long distance correlation. 



Ninety-five species are included here. 

 Many of them are referable to the sections 

 of Triletes already proposed (Schopf, 

 1938) ; others are less definitely assigned. 

 Certain relationships between species have 

 been noted when these seemed particu- 

 larly evident. Triletes is by no means 

 an exclusively Paleozoic genus and Meso- 

 zoic forms have also been included for 

 sake of completeness. Several new names 

 have been proposed here, in addition to 

 the considerable number of new combi- 

 nations required in order to follow a 

 consistent and relatively uniform tax- 

 onomic policy.
