LYOOPODIALES— SIGILLAEIEiE— STIGMARIA. 245 



synonymy ^ of Stigmaria ficoides, as are also the rednced figures given by Mar- 

 tin and Steinhauer. We appear, therefore, to have had in use for this Stigmaria 

 a sufiiciently defined and illustrated binomial appellation of earlier date than 

 the name proposed by Sternberg. Hence, if this'is true, we should, in the con- 

 sistent observance of laws generally just and tending to imiformity and preci- 

 sion in paleontologic nomenclature, employ the earlier name of the species, 

 although conscious of the annoyance or disadvantage to geologists and others 

 not in close touch with paleobotanical literature resulting from the reference 

 to this most familiar fossil imder an entirely unfamiliar specific name. 



Among the specimens in the present collection is one with rather dis- 

 tant pits, the intermediate surface being rugose and irregularly wrinkled 

 longitudinally. It is difiicult to say, however, to what extent these charac- 

 ters may be due to the pressure the fragment has evidently undergone.

 the same region, transmitted by Dr. J. H. Britts.

"I have not thought it necessary to reiigure the common aspects of Stigmaria ficoides with its 

 attached rootlets. Every geologist is familiar ivith these forms. Such figures have been well sup- 

 plied by Martin under the name of Phytolithus verruooaus; by Artis as FicoicUtes furcatus, I'errucosus, 

 and major; by Lindley and Hutton and by Corda as Stigmaria ficoides." (Williamson, Monograph of 

 Stigmaria ficoiden, 1887, p. 2.)
