NEW AND LITTLE-KXOWN WAVERLY FOSSILS. 43 



lapse, but upon what form Phillipsia lodiemis may have been founded re- 

 mains to be seen. Collectors are generally agreed that the species as char- 

 acterized by Meek does not occur at Lodi or elsewhere on that horizon. The 

 evidence is strongly suggestive that the specimen forming the basis of the 

 species was imperfect and distorted. It will also be very interesting to 

 rediscover the Dalmanites described by Professor Clay pole from this horizon. 

 Fhaethonides spinosus is reported from Missouri, though I have not seen 

 specimens. 



PHILLIPSIA (?) CONSORS, HERRICK. 

 {Plate \, fig. 12.)* 



Additional specimens seem to indicate that the numerous pygidia upon 

 which this species chiefly rests do not belong to the same species as that 

 represented by the associated glabellje, but that the latter pertain to imma- 

 ture or slightly variant forms of Proetus prcecursor, the resemblance to which 

 was noted in the original description. Pygidia obtained at Akron and Lodi 

 can be identified certainly with that species, though the glabellse exhibit 

 minor points of diflference which may perhaps be correlated with the small 

 size. The glabella of P. consors being, therefore, unknown, it cannot be at 

 present determined whether it represents a Phaethonides, as is quite possible, 

 or a Proetus. 



Figure 12 (plate 1) gives a greatly enlarged view of the pygidium of P. 

 precursor as seen in the shales 40 feet below the Carboniferous conglomerate 

 at Cuyahoga Falls. 



PHILLIPSIA MERAMECENSIS, SHUMARD. 

 {Plate \,flg. 14.) 



This, for the purpose of determining the stratigraphical equivalence of the 

 upper part of the Waverly, is one of the most important species. Until 

 recently the only specimen seen was that figured in the Bulletin of Denison 

 University, volume IV, plate I, fig. 6, which was derived from an isolated 

 exposure immediately below the Chester. More recently other specimens 

 have been found in Scioto county which are derived from the uppermost 

 layers of the Waverly. Some slight variation is observable, but the smooth 

 surface, evenly rounded ribs, and almost obscure margin prevent confusion 

 with other forms. It does appear, however, that Phillipsia serraticaudata 

 becomes gradually modified, in passing from lower to higher strata, in the 

 direction of this species.
