prosoiit in no position to undortiilve, liifking characteristic material of tlie foreign 

 species, and tlic same is true of Sjj. ociojjlicata, which is of the same type as Sjj. 

 cainpestris and which the latter seems to resemble closely. 



The shape :uul surface ornamentation of Sj:). oampestris simulate those of 8p. 

 spiiiosa in the closest manner. In fact, after studying the available material of both 

 forms I find no constant or considerable differences by which they are to be distin- 

 guished. The evidence seen certainl}' indicates that Sp. cmnpmtris White is the same 

 as Sp. spinom N. and P., but I retain a distinct name for the Coal Measure species, 

 fearing lest comparisons of more abundant or more favorable material will disclose 

 differences which have escaped mj' notice. I believe, however, that the Chester species 

 will be found to range into the Pennsylvanian and that these citations of Upper Car*- 

 boniferous representatives will come to rest in the synonymy of 8p. spinosa.
