species has l)een familiar for some time ; but, unless 

 some fault attach to the work of the original nominator — 

 such as the giving of no figure, or of a flagrantly incorrect 

 description, which would excuse the mistake of subsequent 

 writers, the notoriety obtained by any particular form 

 under an incorrect name cannot become an excuse for its 

 ])ermanently retaining a designation rightly belonging to 

 another. A case in point calls for rectification now. 



Among a series of Brachiopoda sent to me some years 

 ago for identification by the late Mr E. Wilson, F.G.S., 

 was a specimen from the Fullers' Earth Rock of Nunney, 

 near Frome. On comparison I found that this example 

 agreed exactly with what Sowerby had originally figured 

 as " Terebi^ahda emai^ginata — discovered at Nunney, near 

 Frome."* But for many years we have been giving the 

 name eniarginata to a more elongate and flatter species 

 found at a much lower level, namely, in the Inferior 

 Oolite. The mistake had arisen in this way. Davidson 

 re-figured Sowerby's types in 185 i,t and said that they 

 came from the Inferior Oolite — in other words., that the 

 rock which yielded these specimens at Nunney was 

 Inferior Oolite. With them he figured another specimen 

 which may have been from the Inferior OoHte, but it is 

 admittedly a malformation, and is in any case not like the 

 Nunney specimens of eviarginata. 



Not improbably the assumption that the rocks of 

 Nunney were Inferior Oolite may be traced to continental 

 authors, for in 1849 d'OrbignyljI had put Terebratula 

 eniarginata as a species of his " lO'-' Etage : — Bajocien," 

 which would be translated in English as Inferior Oolite. 



Then, in 1877, Davidson^ figured from the Inferior 

 Oolite of Broad Windsor, two specimens as Waldheimia
