ON THE NAMES OF AMERICAN FUSULINAS 239 



the statements of the author are liable to afford but inadequate 

 means for determining which was the authentic species. 



Very large, very elongated Fusulinas are found in inconceivable 

 multitudes in the Guadalupe Mountains. It is possible that 

 specimens occur which are one-fourth larger than the largest seen 

 by me, but it does not follow that they necessarily belong to a 

 different species. Even if there is a larger form which is a distinct 

 species, it is, humanly speaking, impossible that Shumard could 

 have obtained specimens from this region without much the greater 

 portion of them belonging to the smaller type. It is also, humanly 

 speaking, absolutely certain that even if he had any of the larger 

 shells at all, the smaller ones were included along with them as 

 F. elongata. By implication I restricted the name F. elongata to 

 the smaller form, if, indeed, there is any specific difference. By 

 implication von Staff would restrict F. elongata to the larger form 

 whose existence is hypothetical. Which restriction has priority, 

 if either is valid at all, is a matter of record. Which is the more 

 conservative and reasonable needs no argument. I have really no 

 doubt that the form which I figured in 1908 is the true F. elongata 

 of Shumard, while the status of F. secalica is much less certain and 

 F. centralis has almost no standing at all. Consequently, F. elongata 

 is the proper name for the species; the "new variety" calif ornica 

 is a straight synonym ; and the European or Asiatic form for which 

 Schellwien intended to use the name extensa will be a new variety 

 or species as is subsequently determined. 



Furthermore, von Staff has "emended"^ F. secalica so as to 

 make it include a different species from that identified by me and 

 also probably a different species from that originally described by 

 Say. As to the first statement there can be little doubt, since von 

 Staff's F. secalica is a much more inflated form with much more 

 strongly folded septal walls, and since von Staff himself identifies 

 my Triticites secalicus with his F. centralis Say.^ (Nevertheless, 

 in 191 2 he placed my citation in the synonymy of F. secalica.) 



My Fusulina {Triticites) secalica agrees very closely with Say's 

 description, so that von Staff's F. secalica differs from Say's Fusulina 

 (Miliolites) secalica in the same particulars in which it differs from
